摘要
提出了一种固体火箭冲压发动机性能快速预估方法。在原有模型基础上,加入一维燃烧室热力计算模型和附加阻力计算模型,并以VC++6.0为平台,开发出通用的发动机性能估算模块。该模块以动态链接库为载体,支持Automation,既可以单独应用于动力系统性能估算,也可以作为通用模块,应用于导弹总体设计中,实现总体的快速设计及性能分析。初步使用表明,该方法可快速地预估发动机整体性能,大大缩短了设计周期,能够满足方案设计阶段的精度要求。
A quick-forecasting algorithm for performance of solid rocket ramjet was put forward. Based on the initial model, the one-dimensional chamber thermodynamic calculation model and the additional drag calculation model were taken into account. Taking VC ＋ ＋ 6.0 as platform, the general forecasting module was developed. Dynamic link of the module was used as carrier to support automation, which can not only be individually used for performance forecast of dynamic system, but also be used for general module in the system design of the missile so as to realize quick design and performance analysis of the system. The application results show that the method can quickly forecast integral performance of the ramjet ; in addition, the method can greatly shorten design period and meet accuracy demands at the project design stage.
