三升力面飞机扰动运动线性化模型

以一种新型运输机Ecolifter为参考模型，由飞机的一般运动方程，在扰动飞行条件下．对空气动力和空气动力矩、推力和推力矩进行线性化，结合稳态飞行运动方程，推导出稳态直线飞行条件下，Ecolifter的纵向和侧向线性化扰动运动方程。该方程是三升力面气动布局飞机飞行性能和动稳定性研究及一体化设计的基础。

Three-Lifting-Surface Aircraft Disturbance Motion Linearized Model

In this paper, being as the reference model of the novel cargo aircraft, Ecolifter with three-lifting-surface, under the disturbance flight conditions, by means of the linearized method, through the linearization of aerodynamics and aerodynamic moments, thrust and thrust moments, according to the airplane general motion equations, combined with the airplane steady state motion equations, the disturbance motion in longitudinal and lateral-directional linearized equations of Ecolifter has been studied so that the flight performances and flight dynamic stability, and the integrated design of the airplane with three-lifting-surface can be analyzed.
