挥舞运动 meaning in English
flapping action
flapping movement
up-and-down motion
Examples
- This setting could increase the damping of angular rates and improve the stability . based on bell stabilizer bar , bell - hiller stabilizer bar adds small wing on the two ends of bar . compared with main blades the aerodynamic forces and moments generated by the bar could be neglected
希勒伺服旋翼在贝尔稳定杆的基础上,于两个质量块处添加了小翼,与贝尔稳定杆相比,希勒伺服旋翼自身的挥舞运动借助机械耦合引起旋翼二次变距,起到改善操纵性的作用。 - 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。
