New Rolls-Royce Small Engine Set To Begin Tests To Advance Hybrid-Electric Flight
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the first two paragraphs.
Rolls-Royce today announces its new small gas turbine that has been specifically developed to power hybrid-electric flight is set to begin testing. The engine is part of a turbogenerator system that is being developed for the Advanced Air Mobility market. This includes electrical vertical take-off and landing (eVTOL) Aircraft for Urban Air Mobility and Commuter Aircraft applications up to 19 seats.
The turbogenerator system will complement the Rolls-Royce Electrical propulsion portfolio by delivering an on-board power source with scalable power offerings between 500kW and 1200kW enabling extended range on sustainable aviation fuels (SAF) and later, as it becomes available, through hydrogen combustion. This will open up new, longer routes than electric battery powered aircraft can support as of today.
The press release also lays out these design targets.
- Power – 600-1200 kW
- Voltage – 850 Volts
- Power to Weight Ratio – 4 kW/Kg
- Noise – 62 dbA
- Specific Fuel Consumption v in-service products – 15% better
- MTBO – 10,000 cycles
- Length – 1,500 mm.
- Diameter – < 500 mm.
Note.
- At first look, it appears to be small and powerful.
- If they can meet the Power to Weight Ratio of 4 kW/Kg, this would mean that a 1200 kW engine will weigh just 300 Kg.
- The engine has been designed to run on sustainable aviation fuel and hydrogen.
I wouldn’t be surprised to see this engine used in non-aviation applications.
Electra.aero
I have signed up to FutureFlight‘s weekly newsletter and this week it gave two articles about a new nine-seat airliner called an Electra.aero.
It must be the first airliner named after its web site or vice-versa.
The first article is entitled Electra.aero Gives A Glimpse If Its eSTOL Technology Development Aircraft.
It says this about the aircraft and the company.
As it works on plans for a nine-passenger eSTOL blown-wing aircraft, Electra.aero has posted a short video teasing followers with a glimpse of what it describes as a technology demonstrator. The video shows what appears to be a subscale model of the larger hybrid-electric design, but the Virginia-based company is giving very little away for now.
This week, the U.S. start-up announced the appointment of former Boeing Commercial Airplanes president and CEO James Albaugh to its board of advisors, along with the former Airbus America CEO and FAA Administrator Allan McArtor, and aircraft finance expert Kristen Bartok Touw.
You can also watch a video.
The second article is entitled Electra.aero Uses Truck To Test Gives A Glimpse If Its eSTOL Aircraft Propulsion System And Wing.
It says about more the aircraft.
Electra.aero’s planned nine-passenger eSTOL aircraft is expected to be able to operate from landing strips as short as 300 feet. The company’s blown-wing design and hybrid-electric propulsion system will be key factors in achieving this breakthrough performance for regional air services. At its base in Manassas Regional Airport in Virginia, the company is using a technology demonstrator and a truck to conduct ground testing key systems in preparation for anticipated test flights later this year.
You can also watch a video.
The home page also shows a visualisation of a flight between Washington DC and New York.
Note.
- Blown-wing and blown flaps have been used before on aircraft like the Lockheed F-104 Starfighter, the Boeing C-17 Globemaster and the Blackburn Buccaneer.
- Blown flaps’ use on the Electra.aero, seems to be the first application on a small propeller-driver airliner.
- Electra.aero seems well-connected, which helps in the aviation industry.
- Power seems to come from a hybrid-electric design.
- Being able to operate from landing strips as short as a football field is a unique characteristic.
- Pictures on the web site show the aircraft has eight propellers, with those close to the fuselage being larger.
- A 400 nautical mile range with a 45 minute reserve, a cruise speed of 175 knots and a quiet take-off are claimed.
As someone, who has over a thousand hours in command of a twin-engined Cessna 340A, this aircraft could be the real deal.
- The field performance is sensational.
- The range is excellent.
- Except for the number of electric engines, it looks like an aircraft and won’t put off the passengers.
- It could fly between Washington DC and New York or London and Paris.
According to their web site, they already have a $3 billion order-book.
Rockton To Buy Up To 40 Heart Aerospace ES-30 Electric Aircraft
The title of this post, is the same as that of this article on Aviation Source News.
These are the first two paragraphs.
Swedish investment and aircraft leasing company Rockton has confirmed that it will acquire up to 40 of Heart Aerospace’s regional electric aircraft, the ES-30.
The purchase confirmation converts an earlier letter of intent with the Swedish aircraft manufacturer into firm purchase orders for 20 aircraft with purchase rights for 20 more.
It’s good to see a leasing company getting involved, as it probably means that the finances are viable.
The Wikipedia entry for Heart Aerospace, describes the range of the ES-30 like this.
The ES-30 is planned to have a 108 nautical miles (200 kilometres; 124 miles) fully electric range or a 215 nmi (398 km; 247 mi) range when also using generators powered by aviation biofuel. A range of 430 nmi (800 km; 490 mi) could be possible if only 25 passengers are carried.
These are some UK airport to airport distances.

- Stansted – Schipol – 335 miles
- Stansted – Wick – 472 miles
- Sumburgh – Bergen – 226 miles
- Sumburgh – Kirkwall – 85 miles
Note.
- I have included Schipol, as in certain areas of the UK, passengers sometimes fly long-haul from Schipol.
- I have included Haverfordwest, as it will be close to all the wind farm activity in the Celtic Sea.
- I have included Anglesey, as I think it has possibilities.
- The distances wee calculated using on of the Free Map Tools.
These are some more specific thoughts.
The Basic ES-30 And The UK
With a range of 124 miles, I don’t believe that the range is long enough for the UK.
But saying that there are some established routes, where it should be able to operate.
- Glasgow – Belfast
- Glasgow – Belfast City
- Glasgow – Derry
- Haverfordwest – Waterford
- Haverfordwest – Newquay
- Inverness – Kirkwall
- Liverpool – Haverfordwest
- Liverpool – Ronaldsway
- London City – Norwich
- Newquay – Cardiff
- Newquay – Scillies
- Ronaldsway – Belfast
- Ronaldsway – Belfast City
- Ronaldsway – Dublin
- Ronaldsway – Glasgow
- Ronaldsway – Leeds
- Ronaldsway – Manchester
These routes have the following in common.
- They are mostly between major airports with advanced facilities.
- Most airports served have access to renewable electricity.
- Some of the routes can support hundred seat airliners.
- Fifty percent go to the Isle of Man.
I can see several routes between the UK and the island of Ireland and to and from the Isle of Man using ES 30 aircraft.
The Extended Range ES-30 And The UK
The 247 mile range of the extended range ES-30, brings lots more routes into play.
Key routes could be the following.
- Aberdeen – Kirkwall
- Aberdeen – Sumburgh
- Anglesey – Cork
- Anglesey – Shannon
- Birmingham – Belfast
- Birmingham – Dublin
- Birmingham – Newcastle
- Birmingham – Newquay
- Glasgow – Kirkwall
- Glasgow – Stornoway
- Heathrow – Newquay
- Inverness – Sumburgh
- Liverpool – Belfast City
- Liverpool – Dublin
- Liverpool – Norwich
- London City – Haverfordwest
- London City – Humberside
- London City – Manchester
- Newcastle – Belfast City
- Newcastle – Cardiff
- Newquay – Brest
- Newquay – Cork
- Newquay – Deauville
- Newquay – Dinard
- Newquay – Dublin
- Newquay – Guernsey
- Newquay – Jersey
- Newquay – Nantes
- Newquay – Waterford
- Ronaldsway – Birmingham
- Ronaldsway – East Midlands
There will also be other routes.
The Extended Range With 25 Passengers ES-30 And The UK
The 490 mile range of the extended range ES-30 with only 25 passengers, brings a few more routes into play.
- Birmingham – Edinburgh
- Birmingham – Glasgow
- Birmingham – Inverness
- Birmingham – Kirkwall
- Birmingham – Schipol
- Birmingham – Wick
- Edinburgh – Schipol
- Gatwick – Edinburgh
- Gatwick – Schipol
- Glasgow – Sumburgh
- Humberside – Schipol
- Leeds – Schipol
- Manchester – Schipol
- Newcastle – Newquay
- Newcastle – Schipol
- Newquay – Orly
- Newquay – Rouen
- Norwich – Schipol
- Southend – Schipol
- Stansted – Aberdeen
- Stansted – Edinburgh
- Stansted – Inverness
- Stansted – Glasgow
- Stansted – Schipol
- Stansted – Wick
Note.
- All airports East of Birmingham and Manchester seem to be close enough to Schipol for an Extended Range ES-30 with 25 passengers to serve the route.
- Most major Scottish Airports can be reached from Stansted.
- Flying from Gatwick to Scottish Airports is around forty miles longer than flying from Stansted.
Liverpool Airport
Liverpool Airport could be a major destination for the ES 30, as it could be a key airport for flying between the UK and the island of Ireland.
Liverpool would obviously need the electric infrastructure, but I also believe it needs a better connection to the major railway station at Liverpool South Parkway, which has extensive rail connections.
This Google Map shows the area between Liverpool South Parkway station and the airport.
Note.
- Liverpool South Parkway station is marked by the red arrow in the North-West corner of the map.
- The airport is in the opposite corner, with the terminal to the North of the runway.
- The main railway between the South and Liverpool Lime Street passes to the South of the station.
- The A561 passes across to the South of the railway and to the North of the airport.
I suspect some form of people mover like the Luton DART can be built between the station and the airport.
It should be noted that as Hunts Cross has only one platform for Merseyrail Northern Line trains and this could be a factor in limiting the line’s capacity. So could a second platform be installed at the airport to both act as an airport station and to increase the frequency on the Northern Line?
I believe that in a couple of years, journey times between Euston and Liverpool South Parkway will be under two hours and they will only get shorter with High Speed Two. With a fast connection between the airport and the station, there could be a sub-three-hour zero-carbon route between London and the island of Ireland.
- Avanti West Coast Class 805 train to Liverpool South Parkway.
- People mover to the airport.
- Electric aircraft on the 140 miles to Dublin.
Dublin air traffic are usually efficient in getting planes in quickly.
Glasgow Airport
Glasgow Airport could be a major destination for the ES 30, as it could be a key airport for flying between the UK and the island of Ireland.
As with Liverpool Airport it needs a better connection to the rail network.
If Glasgow Airport is successful running zero-carbon aircraft to Ireland, this could change all previous thinking on a Glasgow Airport Rail Link.
Ronaldsway Airport
Geography and electric airliners could be very kind to Ronaldsway Airport and the Isle of Man.
- Electric airliners can easily reach much of the island of Ireland and the UK mainland between Glasgow and Birmingham, from Ronaldsway Airport with ease.
- The Isle of Man will in a couple of years be surrounded by wind farms.
- With other developments on the island, it could sell itself to the UK and Ireland, as a green holiday destination.
But what would the motorcycle enthusiasts say?
Anglesey Airport
I believe that Anglesey Airport could be brought to life in a big way by electric aircraft like the ES-30 or the Eviation Alice.
These are flight distances from Anglesey Airport.
- Anglesey – Belfast – 109 miles
- Anglesey – Belfast City – 109 miles
- Anglesey – Cork – 192 miles
- Anglesey – Derry – 163 miles
- Anglesey – Dublin – 71 miles
- Anglesey – Ronaldsway – 58 miles
- Anglesey – Shannon – 186 miles
- Anglesey – Waterford – 130 miles
All of these except for Cork, Derry, Shannon and Waterford would be possible in the basic ES-30.
This Google Map shows the airport, which is also labelled as RAF Valley.
Note that the North Wales Coast Line passes the site on the North-East side.
At present, Avanti West Coast trains take nearly four hours between London and Holyhead.
But later this year, new bi-mode Class 805 trains will replace, the current diesel only Class 221 trains.
- The current diesel only trains take two hours and five minutes between Crewe and Holyhead.
- The current diesel only trains take one hour and forty-three minutes between Crewe and London Euston.
- The fastest electric trains take one hour and twenty-nine minutes between Crewe and London Euston.
- High Speed Two trains will take 56 minutes between Crewe and London Euston.
When you consider that a lot of the North Wales Coast Line, is straight and flat, I can see the following times being possible, with some improvement and smart electrification between Crewe and Holyhead and a smaller number of stops.
- Crewe and Anglesey Airport – One hour and twenty minutes
- London Euston and Anglesey Airport – Two hours and fifty minutes
With High Speed Two Classic-Compatible trains, the London Euston and Anglesey Airport time could be below two hours and thirty minutes.
I believe that with a well-designed terminal at Anglesey Airport, this could be the fastest zero-carbon way between London and Ireland.
Haverfordwest Airport
This Google Map shows the location of Haverfordwest Airport in the East of Pembrokeshire.
This second Google Map shows a close-up of the airport.
This map from OpenRailwayMap shows the airport and the nearest railway station.
Note.
- Haverfordwest Airport is at the top of the map.
- Haverfordwest station is at the bottom of the map.
- There are rail connections to Cardiff, Fishguard, Milford Haven, Pembroke Dock and Swansea from the the station.
- Rail passengers for London would change at Swansea.
The road looks good between the airport and the station, so would an electric bus to handle transfers be ideal?
Consider.
- I have flown myself into Haverfordwest Airport and there were no navigation or operational problems that I can remember.
- With all the wind farm development planned for the coast of Pembrokeshire and the Celtic Sea, I feel that an airport in the area with regular flights to London and perhaps Waterford in Ireland could be essential.
- London City and Haverfordwest airports are 167 miles apart
- Waterford and Haverfordwest airports are 94 miles apart
- Quiet electric aircraft may ease any planning problems.
- Will a helicopter base be needed for serving wind farms in the Celtic Sea?
I believe, Haverfordwest Airport could be converted into a high-class airport for the Eastern tip of South Wales.
Haverfordwest Airport could also attract other services, given that the Welsh Government have a policy of not building new roads.
I have a feeling that quiet electric airliners will lead to the development of airports like Haverfordwest as feeder airports for the Heathrows and Schipols of this world.
Waterford Airport
Waterford Airport has recently been expanded and it appears from the Wikipedia entry, they are expecting more tourists.
This Google Map shows the position of the airport and the railway station in Waterford.
Note.
- The red arrow at the top of the map indicates Waterford station on the Northern side of the city.
- The airport is indicated by the blue dot in the South-East corner of the map.
- The airport is about ten kilometres from the City Centre.
In the past, Waterford has been quite a busy airport, but Covid-19 seems to have killed most of the traffic.
So could a zero-carbon service between Waterford and Haverfordwest be profitable?
- Those working with the wind energy in the Celtic Sea might find route useful.
- It would give a low-carbon route between Waterford and South Wales, which some might like.
- I also believe that the novelty of flying in an electric plane would attract passengers.
Waterford and Haverfordwest might be one of those routes, where electric planes might be worth trying.
This Google Map shows the Celtic Sea.
Note.
- Waterford Airport is indicated in red on the South-East corner of Ireland.
- Haverfordwest Airport is on the South-Western tip of Wales.
- Newquay Airport is in the South-East corner of the map on the North coast of Cornwall.
There could be as much as 50 GW of floating wind farms installed in this area.
I feel that there could be a case for a triangular Haverfordwest, Newquay and Waterford service.
Newquay Airport
Newquay Airport has been in the news recently because of the antics of Richard Branson and Virgin Orbit.
This Google Map shows the airport in relation to the town.
Note.
- The airport is in the North-East corner and boasts a long runway.
- The airport serves well over a dozen destinations.
- The town of Newquay is in the South-West corner of the map.
- Newquay station is by the sea.
All of these places would be suitable destinations for electric aircraft.
- Birmingham
- Brest
- Cardiff
- Cork
- Deauville
- Dinard
- Dublin
- Guernsey
- Heathrow
- Jersey
- Nantes
- Orly
- Rouen
- Scillies
- Waterford
Newquay Airport could get very busy with electric aircraft supporting tourism and the developing wind power industry.
This second Google Map shows the town centre and station.
Surely, having the station by Great Western Beach is good marketing.
In The Proposed Mid-Cornwall Metro, I talked about a plan to run an hourly Metro service between Newquay and Falmouth.
This article on Rail Technology Magazine is dated January 2023 and entitled Mid Cornwall Metro Secures £50m In Levelling Up Funding, where these are the first two paragraphs.
Following yesterday’s major Levelling Up funding announcement, the government has pledged an almost £50m grant to improve the railways linking Newquay, St Austell, Truro and Falmouth in Cornwall.
This financial aid to improve Cornwall Rail links represents the only successful bid out of four that were submitted to the Levelling up funding. The improvement scheme will be helmed by a partnership with Great Western Railway and Network Rail.
Note.
- I believe this means the Mid-Cornwall Metro will be built.
- Especially as looks like it will cost less than £100 million.
- As this Metro will serve Newquay, it shouldn’t be too difficult to link the plane with the train, with perhaps a zero-carbon bus.
- The Metro would then link Newquay Airport to the main population centres of Newquay, St Austell, Truro and Falmouth.
- If the Metro could be run using zero-carbon trains, that would surely put the icing on the cake!
The map from OpenRailwayMap shows the route.
Note.
- Newquay is in the North-West corner of the map.
- Trains spend around 6-7 minutes waiting at Newquay.
- The blue arrow in the North-East corner marks Par station, where a chord will be reinstated to allow trains to go between Newquay and St. Austell.
- Par is the nearest station to the Eden Centre.
- Newquay and Par is 20.6 miles.
- The route, then goes along the Cornish Main Line, through St. Austell and then on to Truro.
- Par and Truro is 18.9 miles.
- At Truro the Metro would take the Falmouth branch.
- Falmouth and Truro is 11.8 miles.
- Trains spend around 7-8 minutes waiting at Falmouth Docks
- The total route is just over fifty miles, which probably means that battery-electric trains could work the route with charging at each end, whilst the train is turned round.
This airport and metro combination could give a big-boost to zero-carbon tourism.
Inverness Airport
Inverness Airport has recently been expanded with a station on the Inverness and Aberdeen Line.
Consider.
- Electric aircraft like the ES-30 will be able to reach both Kirkwall on Orkney and Sumburgh on Shetland from both Inverness and Aberdeen Airports.
- Sumburgh would need an extended range ES-30.
- Flights would be a few miles shorter from Inverness than from Aberdeen.
- Kirkwall and Sumburgh is only 85 miles, so there may be possibilities for serving both Orkney and Shetland with one flight.
- Extended range ES-30s might be able to do return trips to Kirkwall without a major charge at Kirkwall.
- I once flew in my Cessna-340 to Kirkwall to see the original turbine, that was placed on the island. There is a lot of cold forbidding sea in the area. Perhaps the slightly shorter trip from Inverness, might be better for everybody’s nerves?
- Just as the oil and gas industry did in the last century, I can see the offshore wind power industry generating a lot of passenger traffic to the Orkney and Shetland Islands.
Both Inverness and Aberdeen can be reached from Stansted by an ES-30 carrying a reduced passenger load.
Birmingham Airport
Birmingham Airport could become a major base for electric aircraft.
The 247 mile range of the extended range ES-30 would allow it to be able to reach the following places.
- Belfast
- Dublin
- Newcastle
- Newquay
- Ronaldsway
Reduce the passenger load slightly to 25 passengers and the plane would be able to reach.
- Edinburgh
- Glasgow
- Inverness
- Kirkwall
- Wick
But Birmingham Airport is only 65 minutes from Euston and will in the future be served by High Speed Two, in under an hour.
The airport also has a large catchment area of its own, who might be tempted to choose flying zero-carbon.
Spokes From Speke
In the 1980s, I went to a presentation from Royal Mail in Ipswich about guaranteed next day delivery of parcels. It was important to me, as I was writing software that needed to get from Ipswich, where it was created to London, where it would be tested and installed on customers machines. We also needed to get copies to our customers in Edinburgh and Aberdeen.
The Royal Mail’s latest concept of Spokes From Speke was described.
- All urgent parcels and First Class mail would be collected from the local sorting office and taken to the local airport, which in our case would probably have been Stansted.
- These consignments would then be flown to Speke Airport as Liverpool Airport was known in those days at around midnight.
- They would then be sorted and reloaded onto other planes to complete their journey.
- The planes would then return home and the parcels and mail would be delivered by truck to the local sorting office.
Aircraft used included Short Skyvans and piston-engined twins. Some we’re the quietest of aircraft.
I have heard or read somewhere that in some airports, there were complaints about noisy aircraft flying in and out in the middle of the night.
Now fifty years on companies are looking to speed up deliveries.
- In the UK, companies are experimenting with 100 mph overnight parcels trains.
- This article on Railway Gazette is entitled Varamis Rail Launches Regular Express Light Freight Service.
- Eversholt Rail are putting money behind converting redundant electric multiple units into parcel trains.
But DHL in the USA are going another way and have ordered twelve Alice aircraft from Eviation.
It looks like the cargo Alice could have a useful load of just over a tonne and a range of around 290 miles.
I can envisage flights of near-silent silent Alices sneaking into and out of airports in the middle of the night to deliver and collect urgent parcels.
Techniques like Spokes From Speke will come again, but this time with electric aircraft.
How Would The ES-30 Compare With An Eviation Alice?
The Wikipedia entry for the Eviation Alice gives these figures.
- Passengers – 9
- Maximum Speed – 300 mph
- Range – 290 miles
- Take-off distance – 840 metres
- Landing distance – 620 metres
Note.
- These are figures that most pilots would expect from an aircraft of this size.
- My Cessna 340 was about the same and about eight percent slower.
- It also had a much longer range.
If you look at my list of flights, these will not be possible.
- Birmingham – Inverness – 363 miles
- Birmingham – Kirkwall – 451 miles
- Birmingham – Schipol – 402 miles
- Bimingham – Sumburgh – 513 miles
Birmingham – Wick – 418 miles - Edinburgh – Schipol – 473 miles
- Gatwick – Edinburgh – 356 miles
- Gatwick – Schipol – 374 miles
- Glasgow – Sumburgh – 300 miles
- Humberside – Schipol – 333 miles
- Leeds – Schipol – 386 miles
- Manchester – Schipol 413 miles
- Newcastle – Newquay – 346 miles
- Newcastle – Schipol – 395 miles
- Newquay – Orly – 351 miles
- Stansted – Wick – 472 miles
- Sumburgh – Bergen – 226 miles
- Sumburgh – Kirkwall – 85 miles
Note.
- Most routes that are too long are to Schipol or Scotland.
- Anglesey appears to have Ireland extremely well covered.
- Birmingham, Glasgow and Liverpool keep their Irish routes.
- Newquay is still a hub, that would promote tourism in Cornwall and only loses the Orly connection, although it keeps the flight to Heathrow.
- Ronaldsway still looks to be a possible zero-carbon airport.
I would suggest that a range of 290 miles, is an ideal one for an electric aircraft in the UK, as it can handle a large number of routes.
These are routes that I feel would attract a large number of passengers.
- Anglesey – Belfast – 109 miles
- Anglesey – Belfast City – 109 miles
- Anglesey – Derry – 163 miles
- Anglesey – Dublin – 71 miles
- Glasgow – Belfast – 106 miles
- Glasgow – Belfast City – 103 miles
- Glasgow – Derry – 121 miles
- Heathrow – Newquay – 212 miles
- Inverness – Kirkwall – 106 miles
- Inverness – Sumburgh – 190 miles
- Liverpool – Belfast – 153 miles
- Liverpool – Belfast City – 151 miles
- Liverpool – Dublin – 140 miles
- Liverpool – Norwich – 180 miles
- Liverpool – Ronaldsway – 89 miles
- London City – Humberside – 145 miles
- London City – Manchester – 161 miles
- Newcastle – Cardiff – 230 miles
- Newcastle – Belfast City – 168 miles
- Newquay – Brest – 140 miles
- Newquay – Cardiff 98 miles
- Newquay – Cork – 180 miles
- Newquay – Deauville – 241 miles
- Newquay – Scillies – 68 miles
- Newquay – Waterford – 150 miles
- Norwich – Schipol – 277 miles
- Ronaldsway – Belfast City – 62 miles
- Ronaldsway – Dublin – 80 miles
- Ronaldsway – Glasgow – 123 miles
- Southend – Schipol – 180 miles
- Sumburgh – Kirkwall – 85 miles
Alice may not be big enough for some routes.
But it will be a wonderful route-proving aircraft for the larger ES-30 and other zero-carbon aircraft.
Conclusion
There will be a lot of uses for battery-electric aircraft in the UK.
MONTE and Eviation Sign Deal For Up To 30 All-Electric Alice Aircraft
The title of this post, is the same as that of this press release from MONTE.
These are the first two paragraphs.
MONTE is delighted to announce that it has entered into a Letter of Intent with Eviation, a leader in clean-sheet, all-electric aviation, to purchase up to 30 all-electric Alice Aircraft.
The Alice is a clean-sheet design, 9-seater aircraft built with industry leading MagniX electric propulsion systems. It is the only flight proven all-electric aircraft of its size. MONTE will provide financing and leasing solutions for the Alice and its associated charging infrastructure to its global customer base of regional aircraft operators.
My experience includes.
- As an engineer, experimenting with battery-powered rechargeable instruments in the 1960s.
- As a pilot, I have over a thousand hours in command of a Cessna 340A, which was powered by two piston engines.
- As a driver, I have owned and driven some of Colin Chapman’s composite masterpieces.
- As a financier, I have owned half of a finance company that leased large trucks.
The Alice may look futuristic, but it is based on proven engineering, manufacturing and aviation principles.
My leasing experience, leads me to believe, that leasing these aircraft could be a sound business.
I am looking forward to my first flight.
Retired Alaska Airlines Turboprop To Get New life As ‘World’s Largest’ Hydrogen-Powered Plane
The title of this post, is the same as that of this article on KUOW.
It’s increasingly looking like, there will be at least a couple of viable hydrogen conversions of current turboprop aircraft to hydrogen.
Net-Zero Concept Aircraft: Which Designs Are The Current Front Runners?
The title of this post is the same as that of this article on Simple Flying.
The article is a good summary of what may happen in the field of Net-Zero aircraft in the next ten or twelve years.
Hail The Hercules
The title of this post was used on the front page to indicate an article in the Meccano Magazine about the arrival of the Lockheed Hercules in the mid-1950s.
The Wikipedia entry for the Hercules, starts with this sentence.
The Lockheed C-130 Hercules is an American four-engine turboprop military transport aircraft designed and built by Lockheed (now Lockheed Martin). Capable of using unprepared runways for takeoffs and landings, the C-130 was originally designed as a troop, medevac, and cargo transport aircraft.
The aircraft first flew in 1954 and nearly seventy years later they are still doing the same operations, they were designed for, with various reports of Hercules flying to the remote Wadi Seidna airstrip in Sudan.
This Google Map shows the airstrip.
Note.
- There appears to be two runways and some form of operational building or terminal.
- The River Nile is at the East of the map.
It looks like an airfield, where Hercules are intended to be used, even in circumstances, where severe damage has been inflicted to the runway.
When Metier Management Systems and Artemis were sold to Lockheed, I had several conversations with senior people and the company was and probably still is rightly proud of its long-lived design.
EU Co-Legislators Agree On SAF Blend Targets For Aviation
The title of this post, is the same as that of this article on Renewables Now.
These are the first two paragraphs.
The European Council and the Parliament on Tuesday reached a provisional political agreement on the ReFuelEU Aviation proposal, which will set new rules requiring fuel suppliers to blend sustainable aviation fuels (SAF) with kerosene in increasing amounts from 2025.
The European Commission, which made the proposal, welcomed this outcome on Wednesday and noted that the measure is expected to reduce aircraft carbon dioxide (CO2) emissions by about two-thirds by 2050 versus a “no action” scenario. The ReFuelEU Aviation initiative is part of the “Fit for 55” package.
Measures include.
- Aviation fuel companies to make sure that at least 2% of the fuel they supply at EU airports in 2025 is SAF.
- This share is supposed to gradually increase and reach 70% in 2050.
- A minimum share of synthetic fuels will be required from 2030.
- Aircraft operators departing from EU airports will be required to carry only the volume of fuel they need for a particular flight in order to avoid further emissions associated with extra weight or carbon leakage caused by tankering practices.
- Airports to ensure that their fuelling infrastructure is fit for SAF distribution.
Note.
- I can see some airlines complaining about some of these measures.
- I can also see the fourth measure about tankering having negative effects on airline costs and ticket prices.
Michael O’Leary’s comments will be interesting.
BAE To Produce Batteries For Electric Passenger Plane
The title of this post, is the same as that of this article on The Times.
This is the first paragraph.
BAE Systems is stepping back into the world of passenger aircraft manufacturing by partnering with a Swedish electric planemaker.
I must admit, that I’m not surprised about BAE Systems’s decision.
Aviation needs batteries for many purposes including drones, starting aircraft and auxiliary power sources, so I wouldn’t be surprised that BAE Systems know their batteries.
In The Big Beast In Your Electric Bus, I described the company’s involvement in providing batteries for electric buses in the United States.
As a former private pilot, I’m watching electric aviation with interest.
I am also an applied mathematician and control engineer and feel that electric aviation will always be playing catch up against planes powered by hydrogen and sustainable aviation fuel.
Look at some of Airbus’s ZeroE designs, which use hydrogen fuel.

Discover the three zero-emission concept aircraft known as ZEROe in this infographic. These turbofan, turboprop, and blended-wing-body configurations are all hydrogen hybrid aircraft.
Although saying that there are large numbers of orders for electric airliners like this Swedish design and the Eviation Alice.
Offshore Drone Challenge Takes Off
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
German energy company EnBW and its project partner, the German Aerospace Center (DLR), have published the conditions of entry and the specific flight tasks for the Offshore Drone Challenge (ODC) for the first time.
This is the first paragraph.
As part of the Offshore Drone Challenge, drone manufacturers and service providers are invited to demonstrate their technologies for transporting maintenance equipment to offshore wind farms.
It’s an interesting idea and would make a good television program.
But I suspect, that the winner will be a Ukrainian company, as recently, they’ve had a lot of practice delivering cargoes with a high level of precision into confined and difficult places.
