Space Tourism … and Much More
@1:03 “Main engines at 108%?” as right engine flares up.
that’s normal. the Shuttle launched with engines at 109% rated thrust, and could be throttled up up to 111% in an emergency. the thrust increase was the result of upgrades and performance improvements on the engine design through its time of use in the Shuttle program.
Thankfully, they do not use toxic hypergolic fuels
Did you miss the first three falcon 1 launches?
the Cygnus does use hydrazine for its thrusters.
Yeah, but that was 6 years ago. Over the last 5, OSC has had 3 failures. However, with that said, this could still happen to anyone. Personally, I think what keeps spaceX safe, is their approach to QA which is to monitor everything, and stop on anything.
what could cause that flare? turbopump delivering too much fuel? rocket bell failure causing the thrust to fan out?
Breach of some sort. Joint or mechanically caused, something coming apart, allowing high pressure fuel flow that visibly continuously accelerated the fire and subsequent disintegration on that right engine, from the view of the above video. When SpaceX had their single engine failure, part of the nozzle fell harmlessly, the engine shut down and vehicle remained in flight. This has to have been in the turbopump, like you suggest, chamber or piping. May as well make use of this guessing season. 😉
