In-situ calibration of rocket engine thrust measurement system was studied. The principle and method of automating in-situ calibration are proposed and established. Based on the establishment and analysis of the mechanical model of the loading system for in-situ calibration, the mathematical expression of the force of the in-situ calibration loading system is deduced. The factors affecting the force are analyzed. Accurate control laid the foundation of mechanics and mathematics. Based on this, the automatic control theory is proposed and analyzed to realize the automation of the loading system and the data acquisition automation. The principle and application of the device developed by the author to realize the in-situ calibration automation are introduced. The proposed in-situ automatic calibration method and apparatus are suitable for in-situ calibration of thrust measurement of all jet powered engines.
