基于热发射技术的垂直发射装置燃气排导系统分析
|
摘要
为了研究正常发射及意外点火状态下燃气排导系统的受力情况,优化燃气排导系统,提高发射装置的使用寿命,建立了垂直发射装置燃气排导系统流体仿真模型。通过发射试验,获取压力室与排气道力学参数,得出三种不同耐烧蚀材料的烧蚀情况。将仿真数据与试验数据对比,得出压力室底部所受压强最大,压力室周围次之,排气道最小。对耐烧蚀材料的优化提供参考,为新型发射装置的工程设计提供有价值的参考依据。
In order to study the force condition of gas exhaust system under the condition of normal launching and unexpected ignition,optimize the gas exhaust system,and prolong the service life of the launcher,the fluid simulation model of the gas exhaust system of vertical launcher was built. Through the launching test,the mechanical parameters of pressure chamber and exhaust duct were got,and the ablative conditions of three kinds of corrosion-resistant material were obtained. Comparing the simulation data with the experimental data,it is concluded that the pressure at the bottom of a pressure chamber is the largest,the pressure around pressure chamber take second place,and the pressure at exhaust duct is the smallest. It provides references for the optimization of ablative materials and the engineering design of a new type of launcher.
