The dynamic rocket thrust measurement is set forth as a part of the overall ground test problem. Dynamic thrust data obtained with conventional thrust measurement techniques can be distorted because of the transient response of the thrust stand-rocket engine mechanical structure. Distortionless dynamic thrust measurement is shown to be possible if the transfer function of the measurement system satisfies certain criteria. Three independent techniques satisfying the distortionless measurement criteria were investigated both analytically and experimentally, and the results are presented and discussed. The development and use of several dynamic force calibrators are also discussed.
