据NASA的飞行试验表明,在F/A-18 大迎角研究机(HARV)上装了可动式头部边条后,可大大提高飞机在大迎角飞行时的机头指向及攻击机动性,如果与机上的推力矢量系统配合使用,效果更佳。目前,NASA还在进行一些飞行试验,以验证这种前体控制装置对改善飞机大迎角飞行偏航控制能力及机动性所起的重要作用。可动式前体控制装置的飞行试验比推力矢量系统飞行试验的 According to NASA’s flight tests, it is shown that the installation of movable headliners on the HARV of the F / A-18 greatly improves the nose pointing and attack maneuverability of the aircraft at high angle of attack flight , If used with the on-board thrust vectoring system, the effect is better. At present, NASA is also conducting some flight tests to verify the important role played by this precursor control device in improving the aircraft’s yaw control ability and maneuverability at high angles of attack.
