Abstract: 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.
