flapping motion meaning in Chinese
旋翼挥舞运动
Examples
- Many factors were considered in the algorithm such as the helicopter nonlinear flight dynamic model , the time delay of rotor wake , the air compressibility at advancing blade , the stall of retreating blade , the unsteady flapping motion of rotor blades and the aerodynamic interaction among rotor , fuselage , tail rotor and empennage
根据这一方法可以确定为完成直升机机动飞行所需的驾驶员操纵输入及直升机的飞行速度、角速度和飞行姿态的变化历程。 - But the variation of its aerodynamic forces will induce flapping motion and produce the cyclic pitch on the main rotor blades by the bell mixing mechanism . in order to study the effect of bell - hiller stabilizer bar on helicopter stability and control , this paper first analyze the function and the principles , give the flapping equation and a flight dynamic model with bell - hiller stabilizer bar . and then works over the stability and control of uav r - 50 in hover and cruise condition , and analyzed the influence from parameters of the bar to it
为了深入研究希勒伺服旋翼对直升机稳定性和操纵性的影响,本文首先分析了希勒伺服旋翼的功能和工作原理,推导了伺服旋翼的挥舞运动方程,建立了带有希勒伺服旋翼直升机的飞行动力学模型,然后以yamahar - 50无人直升机为例,分析该直升机在悬停和前飞时的平衡、稳定性和操纵性,在此基础上进一步研究希勒伺服旋翼设计参数变化对直升机稳定性和操纵性的影响。
