The revamp finds space for LAPCAT:

"During a 2008 EU-funded study called LAPCAT I, Reaction Engines found that a SABRE variant named Scimitar would be capable of powering a vehicle at cruise speeds of up to Mach 5. This was the first major government research contract and was worth €2 million. The LAPCAT I contract for the pre cooler represented the first opportunity to demonstrate its world-beating heat exchanger design and manufacturing capabilities."

It does look as if Skylon has been airbrushed out. That NASA analysis can't have pulled its punches!

This looks interesting:

Hmmm... can't see Skylon on the new website! Maybe it's time to rename this thread or start a new one and call it "Reaction Engines Ltd - Synergetic Air Breathing Rocket Engine (SABRE).

I started this thread nearly 11 years ago as a die hard Skylon fanboy who hadn't got around to reading all his books on space exploration and rocket development. Now I'm a little bit wiser on the technical difficulties and economics of single stage to orbit and full reusability it makes sense that Reaction Engines is concentrating on SABRE for multiple applications and seems to be making good progress.

It's great to see SpaceX leading the way with making space access more affordable. However, Skylon still looks awesome  :D

Too true about Skylon, when I first saw it I could not stop looking at it.

Looking very antiquated, the concept of the 3-engined transport wasn't absolutely
dead after WW II, as can be seen by the Northrop -23/25.
Here it was SNCAC, using again this old formula for the NC.300.
Some data : 3 Wasp Junior engines, max.speed 265 km/h, range with 2000kg payload
1000 km, with 2500kg 500 km, take-off run approx.500m to clear a 20m obstacle.

By the way,

there was also NC.301,but no details are known.

Awesome discoveries, RyanC and sienar, thanks for these!

It's annoying though that Hughes reused the H-1 designation which was already that of his 1935 racer...

My dear Hesham, the stuff I found is found here:

LINK

LINK 2

link 3

reprinted in the Truman Committee senate hearings; because Hughes was still butt-hurt over losing the P-38 competition to Lockheed, so for some reason these documents were entered into the congressional record.

I've been looking through these documents and found the 2 place design Hughes submitted to this competition under the H-2 designation.

Just found NASA's official LUVOIR site through a Google search. I thought it might be of interest.
