摘    要:针对共轴刚性旋翼复合式高速直升机构型,分析了其操纵特点,提出两种配平操纵方式:切换操纵方式和耦合操纵方式,并分析了两种操纵方式的优缺点。从多操纵面的冗余控制出发,对耦合操纵方式的操纵规律进行了配平分析,并根据配平情况评估了旋翼和尾推桨的载荷结果。研究结果表明,共轴刚性旋翼高速直升机旋翼的总距操纵、周期操纵与飞行速度、机身俯仰角有一定关系,旋翼载荷和常规直升机相比大幅增加,同时和机身俯仰角也密切相关。

关 键 词:共轴刚性旋翼  操纵  载荷  旋翼  配平

Control and Load Research of Coaxial Rigid Rotor Compound High Speed Helicopter
Institution:China Helicopter Research and Development Institute, Jingdezhen, 333001, China
Abstract:For the coaxial rigid rotor compound high speed helicopter configuration, two trim methods of operation manner are put forward by analyzing the characteristics of operation: the switching operation manner and the coupling operation manner. The advantage and disadvantage of two operation manner are analyzed emphatically. From the redundant command of multi-control surface, the control rules of coupling operation manner are acquired by trim analysis. At the same time, the loads of the main rotor and the rear propulsive rotor are evaluated according to the trim results. According to research results, the collective control and the cyclic control of main rotor of coaxial rigid rotor high speed helicopter are associated with flight speed and airframe angle of pitch, and the loads of the main rotor have a big increase from current helicopter, at the same time, are also associated with airframe angle of pitch.
Keywords:coaxial rigid rotor  operation  load  rotor  trim
