摘要
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。
In this paper, the effects of thrust vectoring on aircraft's stability and controllability are studied. The correlations between the deflection angles of pitch TVC, yaw TVC and areodynamic conrtol surfaces have been achieved. On the basis of the correlations, numerical simulations and analyses are carried out by using the equations of motion of aircraft in the poststall domain. The results show that the application of thrust vectoring control technology extends the flight envelope of aircraft, and improves aircraft's stability and controllability at high angles of attack. Canard and TVC cooperate with each other in controling aircraft effectively.
