Method for acquiring and processing jet flame measurement data of scramjet engine

Abstract

A scramjet engine jet flame measurement data acquisition and processing method adopts a medium wave thermal imager, a long wave thermal imager, a high-speed visible light camera and other measurement devices to measure the whole jet flame of a scramjet engine to acquire jet flame multi-spectrum measurement data, and obtains the jet flame measurement data based on the measurement data. The nozzle temperature characteristics, the jet flame radiation characteristics and the jet flame morphological characteristics are extracted respectively, and the jet flame characteristics are comprehensively described in multiple dimensions. According to the invention, the operation state of the engine can be better monitored, and the accuracy and reliability of jet flame identification results of the scramjet engine are improved.
