| 摘 要： | 不可调固冲发动机在飞行中常处于非设计工作点,为改善该类发动机工作性能,目前大多采用燃气流量调节法.若同时调节冲压喷管,则可大幅改善固冲发动机的适应性.基于一维气动理论,建立了可调冲压喷管变流量固冲发动机的数学模型,计算得到了其工作特性.分析表明,与不可调固冲发动机、燃气流量可调固冲发动机相比,可调冲压喷管变流量固冲发动机具有工作域大、阻力低、溢流少、进气道总压损失少及比冲高等优势.

| Abstract: | Nonadjustable solid ducted rocket is usually unable to operate at the design point all the time.In order to improve the performance of this kind of motor,flux-adjustment is adopted currently.Adaptability would be improved if ramjet nozzle is adjusted at the same time.Based on one-dimension aerodynamics,the math model of flux-adjustable and ramjet-nozzle-adjustable solid ducted rocket was built,and its performance was obtained during simulation.Analysis shows that compared to nonadjustable solid ducted rocke... |
