RAF Seeks Zero Emissions Trainer

RAF doing market exploration for military certified zero emissions light training aircraft ? Alert 5

RAF doing market exploration for military certified zero emissions light training aircraft

The U.K.’s Defence and Security Accelerator (DASA) has launched a Market Exploration called Zero Emissions Air System, on behalf of the Royal Air Force (RAF).

The RAF is searching for its next generation of light flying training aircraft that must be more environmentally friendly and produces a zero carbon emission at the point of use.

The light aircraft must have an endurance of around 90 minutes with a turnaround time of not more than 20 minutes. This will include replenishment of the powertrain energy source, which can be electric or hydrogen based.

The current EFT trainer, the Grob Tutor, isn’t producing much in the way of emissions at the moment...

I suppose we could bungy it off a ridge - that would be green but the pilot's trousers might be brown if the ridge isn't working.

The requirement says "zero carbon emission at the point of use". Unless you have a launch failure you should never be less than 1000' from the winch. Failing that, auto-tow with a Tesla?

Conservation of energy; you don't create heat, just shuffle it around.

That nasty glider is fibreglass so it isn’t really green, what you need is wood and fabric, here are some I took earlier.

Sorry if they are not as sharp as normal he was about 600ft to 1000ft above me and I was trying to heave a 500mm around above my head.

I'm afraid the bungy method produces carbon at the point of use, those hanging on and stretching the bungy. Detail, detail, sorry to be a spoil sport. Must be a way though, if a UK power station can go from burning coal to shipping in timber from the US and burning that and be considered carbon neutral........

No, just a pragmatic , and amusing,response from experienced people.
The idea that reducing emissions will be cheap and easy is delusional.
Lithium batteries have about a sixtieth of the energy density of JetA1.
Its called physics.
It trumps wishful thinking every time.
