Description
Technical Field
The utility model belongs to the field of test temperature measurement of an attitude and orbit control engine, and particularly relates to a cooling device of a spectrum radiation thermometer for an attitude and orbit control engine.
Background
In the process of the attitude and orbit control engine test, the temperature of the outer wall of the engine combustion chamber is one of the important parameters measured in the test, and the temperature of the engine combustion chamber which stably works is as high as 800-2000 ℃. By measuring the temperature change of the combustion chamber, the working performance of the engine can be timely and effectively reflected, and an important criterion for emergency shutdown is provided for the test. Currently, a single point infrared pyrometer is typically used to make non-contact measurements of the high temperatures generated during the test. However, the emissivity of the engine surface varies continuously with the test process, and the infrared pyrometer cannot measure the true temperature of the combustion chamber wall in real time. Based on the above, the most advanced method at present adopts multispectral radiation temperature measurement, namely, according to the spectral radiation information under different wavelengths, the radiation brightness measurement information of the wall surface of the combustion chamber of the engine is acquired, and then the actual temperature and the spectral emissivity of the combustion chamber are obtained through data processing.
Since the attitude and orbit control engine test is performed in a vacuum chamber, the vacuum pressure is generally at (1×10 -3 Between 200) Pa, the heat generated by the spectrum radiation thermometer cannot be timely radiated, and if the heat is accumulated for a long time, the electric element exceeds the working temperature range of the device, so that the working state is abnormal. At present, a cooling device for a spectrum radiation thermometer does not exist. Therefore, how to effectively control the working temperature of the spectrum radiation thermometer and ensure the long-time working performance of the spectrum radiation thermometer under vacuum is a problem which needs to be solved at present.
