结合某典型飞机研究了推力矢量控制对飞机纵向和横航向操纵性、稳定性的改善作用,分别确定了俯仰推力矢量控制和偏航推力矢量控制与常规气动操纵面之间的交联关系,并且利用此关系和推力矢量飞机的动力学模型在过失速区域内进行了仿真计算分析。结果表明,推力矢量控制可使飞机的飞行包线有较大扩展,在大迎角情况下使飞机的操稳特性得到明显的改善;鸭翼与推力矢量控制能够很好地配合对飞机进行有效的控制。
The effect of thrust vector control on the maneuverability and stability of the aircraft in both longitudinal and transverse directions is studied with a typical aircraft. The relationship between pitch thrust vector control and yaw thrust vector control and the conventional aerodynamic control surfaces are determined respectively. Using this relationship and the thrust vector aircraft dynamics model in the stall area of the simulation calculation and analysis. The results show that the thrust vector control can greatly expand the flight envelope of the aircraft and significantly improve the handling characteristics of the aircraft at high angles of attack. The canard and thrust vector control work well with the aircraft control.
