The Best Plane That Looks Like An Egg
The title of this post is the same as that of this article on interesting Engineering.
This is the sub-heading.
Celera 500L: Redefining aviation with its unique egg-shaped design, unparalleled fuel efficiency, and affordability.
These are the first two paragraphs.
In the world of aviation, where innovation meets the boundless sky, a groundbreaking aircraft is poised to redefine the future of air travel. Meet the Celera 500L, the brainchild of the Otto Aviation Group, an aircraft that not only boasts a distinctive egg-shaped design but also promises to transform the way we think about flying. Set to enter production in 2025, the Celera 500L is a testament to cutting-edge technology and forward-thinking design, promising to make air travel more cost-effective and eco-friendly than ever before.
One cannot help but be captivated by the Celera 500L’s futuristic aesthetics. Its unmistakable egg-shaped design is a departure from the traditional aircraft we’ve grown accustomed to seeing in the skies. However, this unique shape is not just for show; it’s the result of meticulous engineering aimed at reducing drag and maximizing efficiency.
I suggest you read the article and look at Interesting Engineering’s video.
After that have a good look at Otto Aviation’s web site.
Brief details of the business aircraft version are scattered through the pages.
- Passengers – 6
- Range – 5,000 miles
- Fuel-consumption – 33 miles per gallon.
- Power – Single pusher diesel engine.
The Otto Aviation web site, explains how it is done using laminar flow and advanced aerodynamics.
There is also this page on the ZeroAvia web site, which is entitled ZeroAvia & Otto Aviation Partner to Deliver First New Airframe Design with Hydrogen-Electric Engine Option.
Is a new world of aviation emerging?
Extending The Elizabeth Line – Could Open Access Services Use The Elizabeth Line?
In the February 2024 Edition of Modern Railways, there is an article which is entitled First Bid For Sheffield To King’s Cross Paths.
The article is mainly about FirstGroup’s proposal for a new Sheffield and London service, running under the Hull Trains brand.
But, this is the last paragraph.
Modern Railways understands First is working on a number of proposals for additional open access services, and this is an early statement of intent. Other existing open access proposals include Grand Union Trains’ plans for London to Stirling and Cardiff to Edinburgh services, along with an already approved London to Carmarthen service, and the recently submitted Wrexham, Shropshire and Midland Railway application for a London to Wrexham service. It is understood other organisations, including MTR and Virgin, are also working up plans for new open access services.
The respected Modern Railways magazine seem to think, that we’ll be seeing more open access services on UK railways.
These are my thoughts.
A Simple Example – London Crosslink
In Extending The Elizabeth Line – London Crosslink, I said this.
In the Wikipedia entry for the London Crosslink, this is the introduction.
London Crosslink was a passenger train service operated by Anglia Railways between Norwich and Basingstoke, using the North London Line to bypass central London. Class 170 Turbostar diesel multiple units were used, and the service operated between 22 May 2000 and 28 September 2002, supported by funding from the Strategic Rail Authority through its Rail Passenger Partnership fund.
As it was discontinued and it doesn’t seem to be sadly missed, I’m not advocating its reinstatement, but just looking how it might be run after the full opening of the Elizabeth Line.
But surely, there were good reasons, why the service was run in the first place and there might be a need in the future.
These are some characteristics of the service.
- There were about half-a-dozen services in both directions every day.
- At its full length it ran between Norwich and Basingstoke.
- Stops included Diss, Stowmarket, Ipswich, Colchester, Witham, Chelmsford, Ingatestone, Romford, Stratford, Highbury & Islington, Camden Road, West Hampstead, Brentford, Feltham, Staines, Woking and Farnborough (Main).
- Each service seemed to have a different stopping pattern.
- The timetable wasn’t very regular.
- The route wasn’t fully electrified.
It appears that it may have been a difficult service to timetable.
I lived North of Ipswich for some years.
I never used the London CrossLink service, as I had moved away before the service started in 2000.
- I would have found the change to the Central Line at Stratford station useful.
- I would have found the change to the Victoria Line at Highbury & Islington station useful.
- I would have found the change to Thameslink at West Hampstead station useful.
- Basingstoke would have given access to Greater South-West England.
- I could have got a bus to Heathrow from Feltham.
But getting to Marylebone, Paddington and Waterloo would have still been tedious.
Could a replacement for the London CrossLink be routed via the Elizabeth Line?
- The service would use the Elizabeth Line between Stratford and Reading.
- The service would use the Reading and Basingstoke Line between Reading and Basingstoke.
The route has some advantages over the original route.
- Except for the 13.6 miles between Southcote Junction and Basingstoke, the route is fully-electrified.
- Whitechapel will give access to London Overground services.
- Farringdon will give access to Thameslink services.
- There will be a lot of connections at Tottenham Court Road and Bond Street.
- Paddington and Reading will give access to Heathrow, Oxford and West of England services.
- Basingstoke will give access to Greater South-West England.
It is certainly an as-useful route as the original, if not more so.
The Trains
In Extending The Elizabeth Line – Will There Be A Need For Long Distance Class 345 Train?, I set out how a standard Class 345 train could be updated with faster running and a more appropriate interior.
As the Elizabeth Line is likely to need some more trains if High Speed Two is delayed, perhaps some extra trains should be ordered fairly soon.
The Routes
Consider.
- A terminal station would probably need to be electrified to the Elizabeth Line route.
- It would need the infrastructure to turn the trains.
These stations could probably be used as terminal stations.
- Basingstoke
- Bristol
- Cardiff
- Colchester
- Faversham
- Hoo – See Extending The Elizabeth Line – A Branch To The Isle Of Grain.
- Ipswich
- Northfleet – For European services at Ebbsfleet International.
- Norwich
- Oxford
- Rochester
- Southampton
- Southend Victoria
There will certainly be others.
Why Use Open Access?
Suppose an operator wants to run a service between Bristol Parkway and Northfleet to give the West Country access to European services.
- The operator takes all the risk and Network Rail get track access charges.
- Do Transport for London get track access charges for the Elizabeth Line tunnels?
- If they get their predictions and sums wrong, they lose the money.
But if they get it right, they probably sell it to an infrastructure company at a profit.
Conclusion
I think open access operation might work through the Elizabeth Line Tunnels.
South Korean Team To Develop SMR-Powered Ships
The title of this post is the same as that of this article on Neutron Bytes.
This is the introductory paragraph.
Nine South Korean organizations have signed a memorandum of understanding (MoU) to cooperate on the development and demonstration of ships and offshore systems powered with small modular reactors (SMRs). The partners will also develop marine systems and the production of hydrogen using molten salt reactors (MSRs).
These points are listed about nuclear-powered ships.
- Over 160 ships are powered by more than 200 small nuclear reactors.
- Most are submarines, but they range from icebreakers to aircraft carriers.
- In future, constraints on fossil fuel use in transport may bring marine nuclear propulsion into more widespread use.
- So far, exaggerated fears about safety have caused political restrictions on port access.
Note.
- When as a child, I used to watch the large container ships at Felixstowe, I thought then, that they could be nuclear-powered.
- One engineering lecturer at Liverpool University in the 1960s, was talking about nuclear-powered tunneling machines.
- Rolls-Royce to name just one company must have the reactor technology.
I just wonder, when the Korean President and his wife visited the UK, just before Christmas, that nuclear-powered ships were discussed.
