Research on Integrated Control Method of Coaxial High Speed Helicopter/Engine
针对常规的旋翼总距前馈方法难以有效实现共轴高速直升机/发动机快速交联控制的问题,本文提出并设计了适用于共轴高速直升机/发动机的新型交联控制方法.首先,基于共轴高速直升机/发动机综合仿真平台,揭示不同运行工况下,共轴双旋翼、推力桨操纵输入、发动机燃油输入变化规律;其次,在此基础上,提出了综合考虑共轴双旋翼、推力桨桨距的增益自调节交联控制方法,并针对不同的运行工况,开展了数值仿真验证.结果表明,在中等、高速度飞行时,相比于常规的旋翼总距前馈,新型交联…查看全部>>
In order to deal with the problem that the conventional collective pitch feedforward method is difficult to effectively accomplish the fast integrated control of coaxial high-speed helicopter/turboshaft engine,a novel integrated control suitable for coaxial high-speed helicopter/engine is proposed and designed.Firstly,based on the comprehensive simulation platform of coaxial high-speed helicopter/turboshaft engine,the variation laws of control inputs of coax…查看全部>>
