Reported in Flight, from a prestigious establishment as Cranfield, the latest in fuel cell engine design ...
At first I thought those "enormous" red things were just a picture, highlighting some internal "gubbings" ... but no ...
Surely, people can see the insanity of this design ? The losses from those heat exchangers must, Must, be massive. and given that the thermal demand (whatever that is, 'cause I don't know) will vary significantly with altitude and outside temperature, then "surely" a more sophisticated installation (more like a P-51 radiator, with a controlled outflow) would be more sensible.
And before people start in with ... this is just a demonstrator, the article crows about the fantastic design this embodies, how ...
"This integration required meticulous planning, iterative design, and close coordination with partner Reaction Engines, to ensure optimal performance,"
and "The decision was taken early on in the programme that before proceeding to ground and flight test, we had to ensure that we had solved the packaging and thermal management challenges that underpin the commercial viability of the technology. Now that this significant milestone has been achieved, ..."
sigh ...
"Hoffen wir mal, dass alles gut geht !"
