建立了线性与非线性两种分布式气动力模型,在弹性飞机模型上添加所建立的气动力模型,验证了整个系统的有效性。对所建立的模型进行着陆及突风扰动动力学仿真,对比线性及非线性气动力模型的飞机动力学响应的差异,结果表明非线性气动力模型能够更合理地计算飞机大迎角状态下的气动载荷及动力学响应。 Two kinds of distributed aerodynamic models, linear and nonlinear, were established. The aerodynamic model was established on the elastic airplane model to verify the effectiveness of the whole system. The dynamics and dynamics of landing and gust disturbance are compared with those of the established model. Comparing the differences between the linear and nonlinear aerodynamic models, the results show that the nonlinear aerodynamic model can more reasonably calculate the aircraft ’ Aerodynamic load and dynamic response.
