Abstract
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 coaxial main rotors and propeller,engine fuel flow under different operating conditions are revealed.Then,an integrated control method with gain self-regulating function is proposed.It consist of the collective pitch of coaxial main rotors and propeller simultaneously.The numerical simulation is carried out under different operating conditions.The results demonstrate that when the high-speed helicopter operates at medium and high speed,compared with the conventional collective pitch feedforward,the proposed integrated control method can decrease the overshoot and drop of power turbine speed by about 36%and 70%respectively,and the fast control quality is superior,which further improve the control quality of the integrated helicopter/engine system.关键词
