I wonder if this was the “Huge News” Eric Berger was talking about?
Also RIP Aerojet.
Yes, this was what Eric Berger was talking about, huge validation of new space given the size and thrust level of this engine.
Yes, this is “huge news”, IMHO.
Not quite running a full pressure, and the mixture is a little rich, but a staged combustion LOX methane test is a great accomplishment.
I believe it’s a first in the US. Aerojet Rocketdyne has been talking about staged combustion LOX rich engines ever since the RD-180 bought for Atlas proved it was possible beyond a shadow of a doubt.
Nice-looking shock diamonds for what little view I got. Best of luck, Blue Origin. BTW, this does NOT spell the “doom” of AJR. There is plenty of room for different types of engines.
I am NOT a “rocket scientist”! I’m a retired “acid-on-the-hands rocket ENGINEER”! 😀
To quote Darth Vader, “Impressive!”. But what data is available about the test?
