直升机智能旋翼后缘小翼参数研究

介绍了用于直升机减振的后缘小翼型智能旋翼相关设计参数的研究。建立了后缘小翼型智能旋翼的气弹动力学分析模型。研究了小翼的关键设计参数:小翼展长、小翼弦长、小翼径向位置、小翼重心布置以及前进比等对后缘小翼偏转角度、驱动机构需用功率以及桨毂振动载荷的影响。参数分析结果用于指导模型的设计并为后续的模型试验提供理论依据。

A Parameter Study for Trailing Edge Flapsof Helicopter Smart Rotor

: This paper presents a parameter study of smart rotor with trailing edge flaps used for helicopter vibration reduction. The aero-elastically dynamic analysis model of the smart rotor with trailing edge flaps is developed for the parameter study of the flaps. Parametric study about span, chord, radial centre, gravity and advance ratio has been conducted to investigate the impact of flap design on flap deflection, power consumption and control authority of hub vibration. The parameter study is used to guideSthe model design and test.
