The invention discloses a two-stage injection aircraft back rapid separation device and method, and the device comprises a jet flow generator which is formed on a carrier aircraft and is used for providing upward jet flow for a separation surface of a secondary aircraft connected with the carrier aircraft so as to offset partial gravity of the second-stage aircraft. The device can provide upward jet flow for the secondary aircraft to form upward thrust, so that the secondary aircraft can rotate relative to the carrier aircraft to do head-up motion to form a first target inclination angle, the pitch angle of the secondary aircraft is increased, the local attack angle is increased, and lift force generated by the secondary aircraft is rapidly increased, and thus, the secondary aircraft can quickly rise to a certain height to avoid collision with the empennage of the aerial carrier. The jet flow generator does not have complex mechanical motion during working, so that the starting speed is high, jet flow can be provided for the secondary aircraft after starting, and the time required for the secondary aircraft to reach the safe height can be greatly shortened.

    本发明公开了一种两级入轨飞行器背部快速分离装置及方法,该装置包括形成于载机上的射流发生器,用于向与所述载机相连的二级飞行器的分离面提供向上的射流以抵消所述二级飞行器自身的部分重力。该装置可以向二级飞行器提供向上的射流形成向上的推力,使得二级飞行器可以相对载机转动做抬头运动形成第一目标倾斜角度,增加二级飞行器的俯仰角,以增加当地攻角使得二级飞行器所产生的升力快速增加,使二级飞行器可以快速上升至一定高度以免与载机尾翼发生碰撞。该射流发生器在工作时没有复杂的机械运动,因此启动速度快,启动即可向二级飞行器提供射流,可以极大地缩短二级飞行器达到安全高度所需的时间。
