某铯盐在丁羟推进剂中的应用初探

Preliminary Study on Application of a Certain Cesium Salt in HTPB Propellant

随着高科技的发展,等离子推进技术受到广大研究者的关注。采用高倍率扫描电镜分析了铯盐的微观形貌,按照国军标检测方法测试了铯盐的撞击感度、摩擦感度及其与固体推进剂主要组分的相容性。结果表明,在微观角度上,铯盐的颗粒粒径较大,表面不规则,这将影响其在推进剂药浆中的流变性;若将其球形化,其药浆的流变性将大大改善;铯盐及含铯盐推进剂药浆感度都较低,且铯盐与复合推进剂主要组分均相容,说明其在复合推进剂中应用是可行和安全的。

Plasma propulsion technology has been concerned by many researchers with the development of high technology.The microscopic morphology of cesium salt was analyzed by using high magnification scanning election microscope.The impact sensitivity,friction sensitivity of the cesium salt and its compatibility with the main components of solid propellant were tested according to the national military standard.The results show that from the microscopic view,the size of cesium salt particles is bigger,its surface is irregular,there will be influence on its rheological property in propellant slurry.If the cesium salt was spheroidized,the rheological property of the slurry will be greatly improved.The sensitivities of cesium salt and propellant slurry containing cesium salt are both lower,and the cesium salt is compatible with the main components of composite propellant.These verify the feasibility and security of the cesium salt application in composite propellant.
