摘　　要：推力测量是高空模拟试验领域重要的研究课题.本文通过某高空台的推力测量,介绍其试验设备、测量方法及试验结果,重点讨论了该高空台的推力修正及测量精度问题.Thrust measurment is one of important research subjects in altitude simulation test. At present, the thrusts of turbojet engines in flight are always examined by means of simulation test in a altitude chamber. The technology in simulation and measurement, the facility, and the measured results are introducted in this paper by showing the thrust measurement conducted in some altitude chamber. Meanwhile, the correction on thrust measurement and the measurement accuracy are discussed emphatically.
