500lbf Rocket Engine Testing

Testing very small throttle movements with a 500 pound-force throttleable rocket engine on Masten Space Systems XA-0.1B rocket vehicle.

The engine runs on liquid oxygen and isopropyl alcohol, and was putting out about 240lbf during the tests.

Im assuming it isnt just the average store bought isopropyl alcohol, the 70% kind.

[bbrockert]

@TheDragonoxx It's 99.9% anhydrous isopropyl. Still the same chemical, and the engine would run on 70%, though at a lower level of performance.

Do you work on these rockets and what are these going to be used for?Cool video.I hope you guys are making commercial space travel soon lol :)

[bbrockert]

Yep, rocket science is my day job. We're working first toward launching suborbital payloads into space (100kg to 100km) and possibly flying people later.

poor metal plate

[bbrockert]

It's actually concrete blocks that are getting toasted. The engine will burn through a metal plate much faster.

@bbrockert I guess it hardly matters... if your buying liquid Oxygen... might as well go all-out with 99.9% alcohol!

[JuryDutySummons]

@bbrockert You can buy 99% stuff at the store... does that extra .9% make that much of a difference?

@bbrockert thats so cool bring me just kidding but sounds really awesome I only launch model rockets
