The fuel flow for any given thrust level can be found from .
This means that the design, while highly efficient, can produce thrust levels of perhaps 1.3 to 1.5 N, making them useful only for thrusters.
At this thrust level, we'll have deorbited within fifteen minutes - make it ten for safety.
The group plans to repeat the test with higher thrust levels.
Less efficient than a propeller at cruise (at lower thrust level).
We spent about half our time experimenting to measure the thrust levels we can achieve.
Dozens of ampules were thus sent back at various thrust levels and a calibration curve set up.
Test results demonstrated that the engine was stable over a wide variety of thrust levels and propellant ratios.
The same basic design was capable of much higher thrust levels after upgrading the turbopump.
The helm also displayed recommended thrust levels for each phase of the spiral.
