Abstract

The invention discloses a phase change engine tail flame temperature testing device and a control method. The device includes an engine combustion chamber, an air injection port, a temperature calibration sensor, an infrared thermometer and a controller. The controller is used to collect a plurality of gas temperature sensors to sense The initial temperature and instantaneous temperature of the exhaust flame of the phase change engine, the initial temperature and instantaneous temperature monitored by the infrared thermometer, and the corrected actual temperature are calculated; the phase change engine exhaust is recorded according to the time interval of the set sampling frequency. The temperature of the flame and draw the temperature-time curve. The invention can automatically calibrate the measurement data of the infrared thermometer, record the process change of the tail flame temperature in real time; accurately measure the tail flame temperature of the phase change engine; and can correct the design and adjustment of the phase change engine by analyzing and researching the measurement data Propellant fuel ratio, optimization of engine infrared radiation characteristics, etc.; the algorithm of temperature average can eliminate the human error in the installation process to a greater extent.

Description

technical field [0001] The invention relates to the field of phase change engine temperature testing, and in particular discloses a phase change engine tail flame temperature testing device and a control method. Background technique [0002] The tail flame is the high-temperature, high-speed airflow injected by the aircraft engine, which is of great significance to the study of the infrared radiation characteristics of the aircraft tail flame, and can provide reliable data for infrared protection. To study the infrared radiation intensity of the plume, it is necessary to know the temperature field, pressure field and composition of the plume. It is of great significance to study the temperature, pressure and composition of the plume for better infrared stealth technology of the plume. The engine flame temperature is one of the important thermodynamic parameters of the combustion process. At present, there are data showing that there is some research on missile flame temper...
