X—31A飞机的设计特点和试飞情况

综述了为验证增强战斗机机动性(EFM)计划、衡量过失速机动飞行的可行性及其在近距空战中的战术价值,X-31A飞机在气动布局、大迎角抗偏离设施、推力矢量系统以及飞控系统方面的特点;介绍了X-31A飞机的有关飞行试验情况,特别是循序渐近的四种过失速机动动作以及空战效能评估结果。结果表明,X-31A飞机气动布局合理,能完成过失速机动飞行。且过失速机动技术和推力矢量组合,可以大大地提高飞机近距空战的作战效能。

On Design Characteristics and Flight TestAchievements of the X-31A Aircraft

Abstract A survey of the aerodynamic configuration , high a anti - departure devices , the thrust vectoring system and the flight control system of the X - 31A is presented, which was initiated to demonstrate the Enhanced Fighter Maneuverability (EFM) Program, i. e. to demonstrate the feasibility of recently emerging post stall technologies and assess their tactical value for close ?in air combat. The flight test program is then outlined, especially on the four step - by - step post stall maneuvers and the inflight tactical evaluation results.The results show that the X -31A aircraft's aerodynamic design is reasonable, it is suitable to fly at post ?stall area. PST and TV may greatly improve fighter's combat effectiveness at within visual range.
