A slightly foggy day – BPM-5 engine test day

Video Caption: BPM-5 engine test day
the 4th of February 2017
As something new, we used our pressurisation 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.
