摘要
根据超声速自由旋涡气动窗口的实现原理以及相关气动设计理论,推导出气动窗口的质量流率公式,得到影响气动窗口质量流率的几个因素,研究了自由旋涡气动窗口喷管设计过程,利用特征线方法设计非对称喷管,得到气动窗口的喷管型面。最后对气动窗口喷管进行了初步数值模拟,模拟结果表明利用特征线方法设计喷管是可行的。
Based on the aerodynamic window＇s principle and aerodynamic theory, a method of nozzle design is presented. The factors influencing the mass ratio are obtained. The design of aerodynamic window is studied, and the curves of nozzle are obtained. Finally numerical simulation is presented to verify the method of nozzle design, and the results of flow parameters in the nozzle show that the characteristics method is feasible for design of free-vortex aerodynamic window＇ s nozzle.
