Abstract

The integrated optimization of turboshaft engine/rotor was studied to analyze the relationship between power requirement of helicopter and the operating status of turboshaft engine

and the effect of the rotor revolutions per minute(RPM)

collective

longitudinal cyclic and lateral cyclic on the power requirement of the helicopter.Linear programming(LP) was used to optimize the turboshaft engine/rotor performance by taking the minimum power requirement of rotor as the objective function.Meanwhile

digital simulation test was conducted for optimization of turboshaft engines with variable rotor speed in cruising state.The simulation results show that

the fuel consumption could decrease by 1.5%5.5% and the turbine temperature decrease by 4.416 ℃ after optimization of turboshaft engine with variable rotor speed in cruising state.
