| 摘 要： | 本文对筋斗和横滚机动飞行的运动学问题进行了分析。所建立的数学模拟方程、边界条件以及非线性迭代求解方法,可以用来计算该机动科目的飞行轨迹、速度(或角速度)、加速度以及载荷因数等随时间的变化。最后,文中给出了实际的算例。这一工作可以为机动飞行动力学的研究提供基础,对武装直升机的战术使用具有实用意义。

| Abstract: | The kinematics of helicopters in loop and roll maneuvers is analysed in this paper. The mathematic model equations,boundary conditions and nonlinear iterative algorithm established herewith can be used to calculate the variations of flight path,velocity (or angular velocity),acceleration as well as load factor,etc,with time for the said maneuvers. Finally, a sample calculation is shown. The study accomplished in this paper not only can lay the foundations for the studies of flight dynamics of helicopters during maneuvering flight,but also be of practical significance in the aerobatic application to armed helicopters. |
