Abstract:

Thrust test, especially micro thrust test, is often disturbed by the pipes or wires connected to the thruster. If the thruster being tested is not fixed on the test stand and only ejects towards a test probe, then the above problem can be avoided. But the probesensed force is different from the real thrust. The relation between the real thrust and the probesensed force by experimental and numerical methods are investigated, respectively. It is founded that they have a linear relationship. With this linear relationship, the real thrust force can be figured out by the probe-sensed force conveniently.
