| 摘 要： | 本文针对多发螺旋桨飞机的特点,推导出用于分析多发螺旋桨飞机动力失速动态特性的计算方程,并用此方程研究了此类飞机带动力的失速动态特性,计算结果与飞行结论相符。 文中提出的理论计算方法,较全面地考虑了螺旋桨飞机所特有的动力效应,因此较准确地反应了多发螺旋桨飞机的动力失速特性。所以,它除了能分析多发螺旋桨飞机的动力失速外,对于研究飞机动力失速的全数字实时仿真和研究失速/尾旋飞行模拟器也有一定的参考价值。

| Abstract: | In accordance with the characteristics of the multiple-engine propeller airplane, this paper derived the calculation equations for analyzing the power stall dynamic characteristics of the multiple-engine propeller airplane and studied the power stall dynamic character-istics of this airplane with these equations.Since the theoretical calculation method presented in this paper has more completely considered the particular dynamic effect of the propeller airplane, so the power stall characteristics of multiple-engine propeller airplane have been more accurately reflected. Therefore, in addition to analysis of the power stall characteristics of the multiple-engine propeller airplane, this calculation method is worth reference for the study of full digital real time imitation of power stall characteristics of the airplane and for the study of stall/spin flight simulator. |
