On Saturday, February 4th we tested our BPM-5 rocket engine.
As something new, we used our pressurization system actively by changing the engine chamber pressure along the way. We tried to keep the O/F ratio constant and change the feed pressure so the chamber pressure would increase.
We would then be able to map the O/F ratio and chamber pressure with just a few tests.
To characterize our BPM100 injector, we needed to go bigger than any other homemade project has gone before. The Spica rocket engine will burn through 50 liters of propellants each second. To simulate that on Read more…
