鸭式旋转机翼飞机过渡段旋翼卸载特性分析

Analysis of unloading characteristics of the canard rotary wing airplane blade in transitional process

针对鸭式旋转机翼飞机在过渡飞行模式下的飞行品质与操纵性问题,首先定义飞机转换过程中的最低转换速度边界和最高转换速度边界,并制定相应的转换操纵策略,同时提出一种以旋翼总距和前飞速度为控制量组成转换边界的分析方法。最后以某40 kg级飞机为样机,计算得出该飞机过渡飞行模式下旋翼卸载过程中的转换边界,计算结果证明了所提出的分析方法的有效性。

Considering the flight characteristics and flight maneuverability of the canard rotor wing plane in transitional flight mode,the lowest and highest transitional velocity envelope for transitional process were defined and the corresponding maneuvering strategy was made firstly,meanwhile,an analysis method was presented in which the transitional boundary was formed by the control variables of blade collective pitch and flight speed. Finally,the transitional envelope for the helicopter unloading process during the transitional flight process of a 40 kg model plane was calculated which proved the effectiveness of the presented analysis method.
