As an important component of modern spacecraft, attitude-control rocket engines have been widely used in satellites, space shuttle and aircrafts. They play a very importance role in attitude adjustment, precision orientation, midcourse correction, docking, rendezvous, separation, braking. The thrust of attitude-control rocket engines is a small pulsed thrust. Accurately measuring the pulsed thrust has important significance to improving engine performance, promoting spacecraft control precision, saving limi...
