本文用飞行力学的处理方法,对一种高空无人驾驶侦察机(以下简称无人机)的侧向制规律的特点进行了分析。重点是分析飞机不对称(因工艺误差,或重复使用时残存的不对称)产生的干扰侧力△C_z,干扰力矩△(?)_s和△(?)_y(均以无因次系数表示),以及在投放初始值β_(10),ω_(x0),ω_(y0),γ_0和ψ_0等的作用下系统的航迹偏角ψ_s和飞机重心侧向位移Z的静差。本文对加上侧向控制规律后,对飞机动态品质的影响也进行了分析,并提出了改进原控制规律的设想。其分析结果可供系统设计者综合方案时参考。
In this paper, the method of flight mechanics is used to analyze the characteristics of the lateral law of a kind of aerial unmanned reconnaissance aircraft (UAV). The focus is to analyze the interference side force ΔC_z, disturbance torque △ (?) _s and △ (?) _ Y (both of which are represented by dimensionless coefficients) due to the asymmetry of the aircraft (due to the process error or the residual asymmetry in repeated use) , And the static difference between the system ψ_s and the lateral displacement Z of the aircraft under the initial values β_ (10), ω_ (x0), ω_ (y0), γ_0 and ψ_0. The paper also analyzes the influence of the lateral control law on the aircraft dynamic quality and puts forward the idea of improving the original control law. The analysis results are available to system designers for reference.
