基于图像传感器的推进剂发烟量测试方法
Test Method of Propellant Smoke Density Based on Image Sensor
摘要
Abstract
A propellant smoke density test method based on image sensor was proposed.In this method, the halogen lamp was replaced by a collimator, the photoelectric diode or photosensitive resistance was replaced by an image sensor, and a lens hood with hollow stripes on surface was designed to modulate light source.The effect of environmental noise on test results was eliminated by image processing method.The combustion smoke densities of SQ2 propellant, Al-CMDB propellant and NEPE propellant were measured.The results show that the transmittance curves of SQ2 and Al-CMDB propellants are basically stable at about 50s after ignition.The transmittance curve of NEPE propellant is stable after 50s of ignition, but has a slow upward trend.The smoke transmittance of the above three propellants are 84.1%,65.9%,22.3%,respectively, which are consistent with those obtained using the traditional test method.关键词
