just musing, have there been any further information released showing the test vehicle in which the intended 'first flight' is to be achieved ?

Their website states that "There are three core building blocks to the SABRE engine, the pre-cooler, the engine core and the thrust chamber. ... We have demonstrated each of these independently over the last four years." Another page adds that "... will culminate in full system testing in 2020, at which point the world’s first air-breathing engine capable of accelerating from zero to Mach 5 will have been demonstrated."
That is all ground-based. The new funding takes off from there. There are certainly few if any unclassified airframes capable of sustaining Mach 5 flight for long enough without breaking up or melting, so likely we will see rather more pedestrian flights to start with and there are a good many opportunities there. I would hazard that whatever sponsors come forward in the new funding round might have something to say about whose plane/s they bolt it to and at what speed/s.
Yes, for the hypersonic tests, surely so. But for lower flight speeds there are plenty of existing candidates bumbling about the sky and running out of things to do. If I were Reaction Engines, I would want to flight-test SABRE's basic operation and low-level performance before I stuck it in an expensive one-off optimised for Mach 5. Much as R-R hung the civil Olympus under an old Vulcan before sticking it in Concorde.I thought they were going to build a purpose constructed flight demonstrator not use an existing airframe.
REL‘s new logo is like Marmite, you either like it or hate it.
Awful. Although might appeal to the gay community...
*without any disrespect. Just to pass the idea while avoiding vulgar language.
I wonder if it looks like this vehicle in their brochure? https://www.reactionengines.co.uk/media?folder=BrochuresConceptual study into hypersonic test bed for SABRE technology :: Reaction Engines

It doesn't look like there is much room for cryogenic fuel tanks in these concepts!

Not sure where the demonstrator puts its undercart either, unless the thing is disposable which seems to undermine the whole point of SABRE.
On the other hand the operational spaceplane presumably has its fuselage filled with hydrogen except for a teensy payload bay. Hope the canard foreplane doesn't melt.
Wonder why they designed it with canard foreplane's? it seems rather stupid (unless they can retract the canard's at some point during the flight)
I don't think that is a showstopper. Viable configurations are known and are evolving all the time and Reaction Engines have learned the hard way to stick with the experts.

Could they be looking at magnetic landing systems, like the Soviets were during the '80s?
Which configurations? So far nothing has worked e.g Skylon dropped.
Well, that would be a step ahead of the rubber trampoline the Royal Navy put up on an aircraft carrier and then landed a de Havilland Vampire on.Could they be looking at magnetic landing systems, like the Soviets were during the '80s?
