Re: SpaceX have turned rocket science into Spaghetti Engineering
"Look at SABRE and Skylon for the radical, new and innovative."
New as is conceived more than 40 years ago and so far only tested as discrete component stages and no integrated motor with pre-cooler has run yet? Reaction were formed in 1989. It has
Unfortunately, British R&D means British investors who are shit-scared to invest and therefore snail-pace development. The guy who came up with the idea retired 4 years ago, they've had 32 years already. There's no chance of a pre-cooled motor being in service in 8 years from now. I'll be shocked if one flies subsonic on a test airframe with three other turbofans to help it. Actually, I'll be shocked if an integrated motor runs on a test stand.
It was reported as something good when RR invested £20 million in RAL. I'm guessing one SpaceX Starship test launch costs more than that.
Unless somebody grows some balls and gives it real backing, RAL are nothing more than a long term academic study.
