The thrust characteristics of axis symmetry nozzle were mainly measured in test. For the nozzle having a vectoring angle, the deflection efficiency was measured too.
For the movable TVC, the thrust and lateral forces with respect to nozzle deflection angles and the depth of water were obtained.
对摆喷管推力矢量方式，获得了推力、侧向力、推力矢量角随发动机喷管偏角以及水深的变化规律。

The average thrust can be obtained by measuring the steady state deflection Angle, and then the total impulse can be obtained from the measured average thrust.
