摘要
首先给出了直升机机动性的定性解释,然后分析了桨盘载荷、桨叶载荷、装机功率、桨尖速度、挥舞铰外伸量和桨叶洛克数六个设计参数对直升机的悬停跃升、平飞加速、定常爬升、定常转弯、减速转弯、高速拉起等六种机动飞行的影响,进而得出了这六种机动性的设计准则,为武装直升机初步设计中的机动性设计提供了依据。
Firstly, the meaning of helicopter maneuverability are introduced. Then, the influence of design parameters on maneuverability are analyzed. These design parameters are disk loading, blade loading, installed power, tip speed, flapping hine offset and blade Lock number, and these maneuvers are hover bobup, acceleration, steady climb, steady turn, decelerating turn, pullup. Finally, based on the analysis above, we developed the design guidelines for improving helicopter maneuverability such as greater installed power, lower blade loading and reduced blade Lock number improve over all maneuverability for the least weight penalty.
