摘要
从飞行性能和控制效能两种优化角度,对三翼面鸭式旋转机翼(CRW)飞机的配平情况进行了研究。采用了物理意义明确的数学方法对CRW飞机进行配平计算,并用两种优化方法对配平状态进行了优化,以得到目标函数下的最优配平状态(最优配平点)。同时验证气动导数估算方法,为CRW飞机的进一步研究奠定了基础。
From the viewpoints of flighting qualities and control efficiency optimization,this paper studied on the longitudinal trimming of the three-surface canard rotor wing（CRW） aircraft.A mathematical method with clear physical meaning was applied to the trimming calculation.Two kinds of optimization method were used to optimize the trimming state so as to obtain the optimal trimming points under the objective function.Meanwhile,the estimating method of the aerodynamic derivatives was validated.As a result,the further research on CRW aircraft was supported.
