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.
Dear readers, The first 100 days in the BPM-100 project has come and gone. And no, unfortunately we haven’t got a working engine here in the workshop. We’ve decided to be a little more thorough Read more…
