将适当简化的药浆涂在不燃带基上,快速固化后形成复合固体推进剂薄层。在此基础上,本文提出推进剂高效燃速仪的技术构想。该仪器由燃烧室、压强和温度控制系统、数据采集和处理系统等组成。燃烧室容纳1650 mm长的燃烧试件,试件上覆盖1051根相隔1.50 mm的熔丝。燃烧室压强控制有三种模式:手工的、台阶式的和线性的。利用手工控压模式可大幅度提高现有燃速测定效率,一次点火能测出燃速的压强指数或温度敏感系数。台阶式控压和线性控压模式相结合,便可能测出燃速的压强函数。
A properly simplified slurry is applied to the non-combustible tape base and rapidly solidified to form a thin layer of the composite solid propellant. On this basis, this paper puts forward the technical concept of propellant efficient combustion meter. The instrument by the combustion chamber, pressure and temperature control system, data acquisition and processing system and other components. The combustion chamber holds a 1650 mm long burning test piece, which covers 1051 fuses separated by 1.50 mm. Combustion chamber pressure control has three modes: manual, step and linear. The manual pressure control mode can greatly improve the existing combustion rate measurement efficiency, a firing can be measured the burning rate of pressure or temperature sensitivity coefficient. Combining stepped pressure control and linear pressure control mode, it is possible to measure the pressure function of the combustion rate.
