• Excuse me , are you one of constable hiller ' s trained killers
  请原谅，你是治安官赫勒训练的杀手吗？
• 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。
• Helicopter is hard to hover precisely for its bad stability . ordinarily , it is improved by flight control system , such like rotorcraft unmanned aerial vehicles which use bell bar or bell - hiller stabilizer bar . bell stabilizer bar , fixed across with teetering main rotor , consists of a bar and masses at two ends
  贝尔稳定杆由一杆与两质量块组成,它与贝尔直升机的跷跷板旋翼垂直交叉放置,这种旋翼装置有助于加大角速度阻尼,改善贝尔直升机的稳定性,但同时也降低了操作性。
