固体推进剂激光点火性能研究综述

Summarization of Laser Ignition Characteristics of Solid Propellants

激光点火的研究近年来已成为一个热门的研究课题,采用激光作为刺激源研究固体推进剂点火性能是因为激光输出能量高且可调、点火时间和能量可控制且不受环境因素限制,而固体推进剂点火性能的研究对揭示固体推进剂的燃烧机理,验证点火模型具有非常重要的意义。本文主要描述了固体推进剂激光点火性能研究的理论过程、表征方法以及试验装置,并对影响固体推进剂激光点火性能的诸多因素如激光能量、推进剂组分及含量、点火环境等因素进行了详细的阐述,最后对固体推进剂激光点火性能研究需要注意的问题进行了总结,并附参考文献50篇。

Laser ignition has been an active research topic in recent years, and laser becomes an attractive future alternative ignition source to study the ignition characteristics of propellants because of its advantages of high and adjustable energy,the ignition time and energy being controllable, and the ignition process unlimited by the surroundings. In addition, the studies of ignition characteristics of propellants contribute to explaining the combustion theory and demonstrating the related model. The brief theory, the characterization and the apparatus of laser ignition of solid propellants at home and abroad were described. And the factors affecting the laser ignition of propellants such as the laser energy, the components and contents of propellants and the circumstances including pressure and temperature, were discussed. In the end, several problems on the evolvement of the laser ignition characteristics of the solid propellants were summarized and concluded with 50 references.
