摘要
建立了四旋翼倾转飞行器旋翼、机翼、机身的非线性气动模型和飞行动力学模型,并在Matlab/Simulink环境下搭建了仿真模型,根据仿真模型计算各个操纵面的操纵效率,确定了不同状态下各个通道需要用到的操纵方式,结合飞行动力学模型和操纵方式,在纵向通道上进行了全包线的配平计算,表明了操纵策略的可行性。
Nonlinear aerodynamic model and flight dynamics model of the quad tilt rotor aircraft are developed by calculating the airframe forces and moments of each component,including rotor,wing and fuselage. A simulation model is built under the Matlab/Simulink environment,then according to the simulation model,the control efficiency of each control surface is calculated,and the control methods used for each channel in different states are determined. Combining the flight dynamics model with control mode,the trimming value with the whole envelope is calculated on the longitudinal channel. The feasibility of manipulation strategies is verified.
