Flight characteristic comparison of STS and DTSbased on mathematical model

  • 摘要: 研究了单级涡轮增压活塞螺旋桨推进系统(STS)的部件法数学模型,给出了STS的联合工作方程组,给出了STS的调节方式,计算了STS的高度速度特性.从总体及各部件的高度速度特性方面比较了STS和双级涡轮增压活塞螺旋桨推进系统(DTS).研究表明:选择的STS调节方式可满足其设计目标,相比于DTS实际功率保持高度为12.5km,STS的实际功率保持高度可达到5.5km;在选用相同的螺旋桨和发动机的前提下,STS和DTS中各部件特性的变化规律基本一致,但STS的推进效率、单位推力耗油率、推进系统总效率在高度速度特性图中的变化范围大大窄于DTS的.
