Rolls-Royce Chief Warren East Spies Rebound For Air Travel
The title of this post, is the same as that of this article on The Times.
It is a must-read article.
This is the first paragraph.
Warren East, the outgoing chief executive of Rolls-Royce, has sounded a bullish note on aviation’s recovery from Covid-19, reporting increased demand from the jet-engine maker’s airline customers and expressing his belief that China will gradually open up to international travel.
Certainly, with all the chaos at the Channel this weekend, people are starting to travel again.
Support For The Military
This is a paragraph in the article.
Tom Bell, head of Rolls-Royce Defence, said the company was in talks with the US and UK militaries about supplying “deployable” reactors for military bases.
I’m sure that a reactor would have advantages to a large diesel or gas-turbine generator to power a military base.
- Military bases need a lot of power.
- It would not need refuelling every day.
- It could be connected to an electrolyser, to generate hydrogen for vehicles.
- It would be a lot quieter.
- I wonder, if it could be transported in a large transport aircraft.
But I feel, it might have other applications.
- It could provide power support after a large earthquake or natural disaster.
- It could provide power in remote or difficult locations.
- If the only power station for a remote community had a catastrophic failure, a deployable reactor could be brought in.
- It could provide power for a large construction site, which would help to decarbonise the construction.
- Power would be zero-carbon at point of generation.
The reactors might even be rail-transportable, so they could be moved to where they are needed safely and quickly.
But I don’t think they would necessarily be the same size as the Rolls-Royce SMRs, which are 470 MW.
A Scalable Reactor
This is a paragraph in the article.
Rolls also has a contract with the UK Space Agency to develop a “micro reactor” for space vehicles and satellites, Bell added. “These are really exciting opportunities for us to not only perpetuate our business undersea, at sea, on land, in the air, but also to go to space,” he said. East noted the advantage of nuclear reactors in space: “You can’t have air-breathing engines on the moon.”
Note.
- East is Warren East, who is the outgoing Chief Executive of Rolls-Royce.
- Nuclear power sources have been used in space before, usually by using an isotope, that gives out heat, as it decays.
- How small is micro?
- The US deployed a 1.75 MW nuclear power plant in Antarctica under the Army Nuclear Power Program. That reactor also provided heating and hot water. It is worth reading the Wikipedia entry, especially the section about the MM-1 reactor.
It does seem that Rolls-Royce are designing a reactor that can be scaled in size, to cover a whole spectrum of applications.
Repowering Zero-Emission Buses As An Alternative
The title of this post, is the same as that of this article on Digital Journal.
The article makes the argument for swapping out the diesel engine for a zero-emission powertrain.
I very much feel that this is a worthwhile idea, as do Ricardo.
I wrote about converting London’s New Routemasters to hydrogen in Could London’s New Routemaster Buses Be Converted To Hydrogen Power?.
The Channel Crossing Problem
My company provided the project management computer system; Artemis, that planned how both the tunnel and the rail link to London was built. So I heard numerous stories of inadequate infrastructure on both sides of the Channel.
I also for a time was a business partner of the man, who had been project manager on a previous attempt to build a Channel Tunnel, that was cancelled by Harold Wilson’s government in 1975, who had a lot of interesting input.
I have heard over the years of these inadequacies,
- The Dartford Crossing wouldn’t be able to handle the traffic generated at busy times.
- The Eurotunnel terminal in Folkestone wasn’t built large enough.
- The port of Dover is too small.
- The roads to the Port of Dover were inadequate.
- The rail terminal at St. Pancras doesn’t have the capacity to run services to the places that are better served by train.
The government only has one major improvement in place, which is a new Thames Crossing, but that will only make matters worse, as more traffic will be tempted to cross the Channel to get to Europe.
It is my belief, that we need more innovative services to provide more capacity.
- A German company called CargoBeamer, is developing a system, whereby unaccompanied freight trailers can be moved thousands of miles across Europe by rail. Their plans include services to Birmingham, Cardiff, Manchester and Scotland.
- I would also run a CargoBeamer service from Calais to Holyhead to create a direct freight service between Ireland and Europe.
- Ebbsfleet needs to be developed as a destination for the Elizabeth Line and an extra terminal for both daytime and sleeper trains to Europe.
- High speed freight trains, based on existing 160 mph EMUs could be used.
- Given the position of the new Thames Crossing on the Isle of Grain, perhaps a new ferry port could be built on the island to partially replace Dover.
- Could some Eurotunnel services start from Watford Gap?
We have to be bold.
The Grade II Listed Next-Train Indicators At Earl’s Court Station Are Back
This page on Rail News has a section, which is entitled Heritage Train Indicators Return To Service, where this is said.
Vintage train describers have returned to the platforms of Earl’s Court District Line station, which is Grade II listed. First installed in 1905 when London’s District Railway was electrified, they have been renovated and given replica destination name plates, which are highlighted as required by an illuminated arrow. The indicators had been switched off while they were connected to a new signalling system. Modern information panels showing the destination and the number of minutes before the next train is due from each of the four platforms have also been installed.
I went Earl’s Court station to have a look this morning and took these pictures.
They all seemed to working as they should.
Earl’s Court station is a Grade II listed London Underground station and Wikipedia says this about these indicators.
On each platform is an old-fashioned “next train” indicator board which had various routes shown, of which one is usually highlighted by an arrow to indicate that this is the route of the next train. As of March 2022, these have been temporarily disabled while signalling is upgraded to CBTC signalling, as part of the 4LM improvement works to the subsurface lines, although are expected to return in June the same year. These have not been replaced by modern electronic equivalents as they are Grade II listed.
There can’t be many next train indicators in the world, that are listed or given the local equivalent.
This does take me all back to the 1960s, when for two summers, I worked in the Electronics Laboratory at a company called Enfield Rolling Mills. The Electronics Laboratory developed control systems for the many machines in the factory. At that time, a lot of the work involved replacing relays and electronic valves with then-modern transistors. I learned a lot about industry in those two summers and it wasn’t all about automation and electronics.
Would a fifteen-year-old be allowed to do a job like that, these days?
I suspect that on that Earl’s Court indicator board, there is some interesting electronics connecting it to the CBTC signalling.
Minding The Gap – Barking Style
There are several ways of minding the gap between the train floor and the platform on railway systems.
- There’s the simple get the geometry right method used on the Elizabeth Line, parts of the London Overground and some other routes.
- There’s Stadler’s method where a gap filler comes out from the train.
But I’d never seen, this simplemethod that is used at Barking Riverside station on the London Overground.
Note the rubber strip, where all the doors on the train are by the platform.
This is a simple device and I’ve never seen it before.
But according to this article on Rail Technology Magazine, it has been in use on Heathrow Express for a year.
The devices are Australian and come from a company called Delkor Rail.
Schoolchildren Get First Glimpse Of Northumberland Line Train Services
The title of this post, is the same as that of this article on the Northumberland Gazette.
The title does say it all, but what a good idea to give the kids a ride first to build up enthusiasm for the new Northumberland Line.
High Speed Two Publish Rural Footbridge Design
High Speed Two have published their rural footbridge design on this page of their web site.
This image from High Speed Two shows an artist’s impression of the bridge.
This is High Speed Two’s own thoughts on the design.
Made of weathering steel, the sides of the lightweight bridges will lean outwards to maximise views of the sky and improve the experience of people crossing the railway.
Weathering steel – which ages naturally to a russet brown colour – was chosen to help match the tone of the surrounding countryside, while the plates that form the structure of the bridges will be angled to appear narrower and lighter.
To emphasise the sense of lightness, each span will be slightly higher in the middle so that they appear to leap over the railway. Most of the bridges will consist of just one 42m span, with extra spans added where necessary to create bridges of up to 102m long.
The design of the bridge would appear to be a good compromise between accessibility, cost, ease of construction and installation and practicality.
The article also covers other topics.
Step-Free
This paragraph explains how the bridges will be step-free.
In order to improve efficiency of manufacturing and assembly, all the bridges will have the same basic form, with the approach paths built into the earthworks on either side of the bridge. This also means that all the footbridges will effectively be step-free.
I can see bridges of this type being built at other rural locations.
A Single-Platform Station
These images show James Cook station in Middlesbrough.
High Speed Two’s rural bridge design could be used as part of a design for a step-free station on a rural line.
Bridleways
The footbridge can be used for a bridge on a bridleway.
Designed with guidance from the British Horse Society, the bridges which carry bridleways will follow the same basic pattern, with a recycled, non-slip rubber deck and the structure acting like a baffle to stop horses being distracted by passing trains.
Footbridges will be 2.5m wide, while bridleways will be 3.5m wide to allow two horses to pass comfortably and safely.
It should be remembered, that horses are flight animals and if they are startled they run, so if say a train went under the bridge, when they were on top, they would most likely go forward and cross the bridge quickly.
I would happily have ridden my stallion; Vague Shot over a bridge like this.
I also think, the design of the bridge in the landscape should allow riders to approach to a safe distance from the bridge and perhaps watch a train or two go through.
Other Animals
I can see other animals like badgers, foxes and hares using a bridge like this.
I also think, that on classic railways, bridges like these could be used to allow farmers to move sheep or possibly cattle over a railway, with some simple design changes.
Conclusion
This bridge has more applications, than the initial one, for which it was designed.
UK-German Energy Link Reaches Financial Close
The title of this post, is the same as that of this article on renews.biz.
These are the three introductory paragraphs.
A multibillion-euro 725 km interconnector between the UK and Germany has reached financial close, paving the way for construction works to begin in the coming months.
The £2.4bn (€2.8bn) NeuConnect interconnector will form an “invisible energy highway” with subsea cables allowing up to 1.4GW of electricity to flow in either direction between the UK and Germany and will help deliver a more secure and resilient energy supply, particularly as more renewable generation is added.
Independent analysis shows the project will create over £1.7bn in UK consumer benefits over 25 years.
Other points about NeuConnect include.
- It has been privately funded by a consortium of over twenty national and international banks.
- It will run between the Isle of Grain and a the new Fedderwarden substation in Wilhelmshaven.
- It should be operational in 2028.
Although, it is bi-directional, it appears that one of its major uses will be to provide Germany with UK wind energy to compensate for the loss of Putin’s bloodstained gas.
easyJet And Rolls-Royce Pioneer Hydrogen Energy Combustion Technology In H2ZERO Partnership
The title of this post, is the same as that of this press release from Rolls-Royce.
These three opening paragraphs outline the project.
easyJet and Rolls-Royce today announced a ground-breaking new partnership, H2ZERO, that will pioneer the development of hydrogen combustion engine technology capable of powering a range of aircraft, including those in the narrow-body market segment.
Both companies have committed to working together on a series of engine tests on the ground, starting later this year and have a shared ambition to take the technology into the air. The objective of the partnership is to demonstrate that hydrogen has the potential to power a range of aircraft from the mid-2030s onwards.
While Rolls-Royce will bring its expertise in engine development and combustion systems, easyJet will contribute its operational knowledge and experience to H2ZERO and will also directly invest in the test programme.
This to my mind is good news.
This paragraph gives details of some of the planned work.
Through H2ZERO, the companies will support an early concept ground test of a Rolls-Royce AE 2100 engine in the UK later this year. This will be followed by a full-scale ground test of a Rolls-Royce Pearl 15 jet engine – a range of location options are being assessed for this including the Rolls-Royce test facility in Mississippi, USA. The programme will build on initial hydrogen combustion and fuel system rig tests that Rolls-Royce is undertaking with both Cranfield and Loughborough universities.
Note.
- The Rolls-Royce AE 2100 engine, powers the Lockheed Super Hercules amongst others.
- Rolls-Royce Pearl 15 powers various business jets.
easyJet and Rolls-Royce certainly have ambitions, and as there is little about the route they are taking to decarbonise, I would assume, that the main purpose of the study, is to find the optimal route.
I have just found this paper on the German Aerospace Centre web site, which is entitled Assessment Of Hydrogen Fuel Tank Integration At
Aircraft Level.
It uses as a baseline aircraft, the Airbus A320neo, of which easyJet have a few!
I suspect that using some of the techniques outlined in this paper, Rolls-Royce could decarbonise an Airbus A320neo.
Aerospace Electrified By New Technology
The title of this post, is the same as of this article on the BBC.
The article is a good summary of the state of zero-carbon aviation.
