Abstract:
The temperature measurement during the liquid rocket engine test is currently done with the contact measurement method.It has high accuracy,but the performance and life of temperature sensing elements are influenced by contact of the measured object,high temperature and corrosion propellant.According to the requirements and the characters of the liquid rocket engine test,an infrared temperature measurement system was designed and established in combination of the advanced distributed non-contact measurement and optical fiber transmission technologies.The nondestructive and wireless measurement,and optical fiber transmission are adopted in the system,which improves the pick-up rate of temperature parameters on the key parts of the liquid rocket engine in running test in severe environment.The establishment of the system has laid a firm foundation for the research on temperature field distribution of liquid rocket engine.
