  1. 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

    為了深入研究希勒伺服旋翼對直升機穩定性和操縱性的影響,本文首先分析了希勒伺服旋翼的功能和工作原理,推導了伺服旋翼的揮舞運動方程,建立了帶有希勒伺服旋翼直升機的飛行動力學模型,然後以yamahar - 50無人直升機為例,分析該直升機在懸停和前飛時的平衡、穩定性和操縱性,在此基礎上進一步研究希勒伺服旋翼設計參數變化對直升機穩定性和操縱性的影響。
