main rotor blade meaning in English
主旋翼桨叶
Examples
- The left skid was substantially damaged . the main rotor blades remained intact but were bent and twisted
主旋翼桨叶被折弯和扭曲，但保持完整。 - Examination of the wreckage trail indicated that substantial damage was inflicted on the aircraft , in particular the main rotor blades , within the first few metres after initial impact
坠机路线调查显示，直升机尤其是主旋翼桨叶，在首次撞击后的最初数公尺受损严重。 - Main rotor blades were severed within the first few metres through contact with small trees and rocks , and the underbelly and right side of the fuselage were damaged substantially
主旋翼桨叶在直升机冲前首数公尺处因碰触地面矮小树丛和石块而断裂，机腹和右侧严重损毁。 - 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。
