简要介绍了电点火具无损检测方法的原理，针对火箭弹发动机中电点火具的特点，利用电点火具的温升曲线，采用神经网络识别技术，对电点火具的质量进行判别，无损检测判别结果与实际发火试验结果基本一致。 A brief introduction to the principle of non-destructive testing method of electric ignition is given. According to the characteristics of the electric ignition ignition in the rocket engine, the temperature rise curve of the electric ignition is used, and the neural network identification technology is used to judge the quality of the electric ignition. Results and the actual fire test results are basically the same.
