The invention discloses an airdrop dropping tube of a folding-wing loitering aerial vehicle and a dropping method of the airdrop dropping tube. The airdrop dropping tube comprises a tube body, a mounting assembly, a battery pack, a parachute opening control assembly, a parachute compartment box, a pilot chute, a main chute, a parachute compartment cover and a parachute opening actuator, wherein acontrol signal output end of the parachute opening control assembly is connected to a control signal input end of the parachute opening actuator; and the parachute opening actuator is mounted on the tube body and used for the locking control of the parachute compartment cover and the tube body. The airdrop dropping tube utilizes the parachute opening actuator to control the opening of the parachute compartment cover without the need for initiating explosive devices, and the airdrop dropping tube can be reset after being powered on and can be repeatedly used. The dropping tube is equipped withthe parachute opening control assembly so as to comprehensively determine a dropping state by acquiring a pressure altitude, an attitude, acceleration and other information through a barometer and anIMU sensor, and control parachute opening through time delay or by controlling the decrease of the pressure altitude, so that the dropping tube is ensured to be fully and safely separated from a carrier aircraft. In the parachute opening process, the pilot chute is firstly pulled out by the parachute compartment cover, and then the main chute is pulled out by the pilot chute to achieve parachute opening, so that the parachute opening success rate can be increased.
本发明公开了一种折叠翼巡飞器空投投放筒及投放方法,空投投放筒包括筒身、挂载组件、电池组、开伞控制组件、伞舱盒、引导伞、主伞、伞舱盖、开伞舵机;开伞控制组件的控制信号输出端与开伞舵机的控制信号输入端连接;开伞舵机安装在筒身上,且用于伞舱盖与筒身的锁定控制;本发明中,投放筒采用开伞舵机控制伞舱盖打开,无火工品,并可上电后复位,可多次重复使用;投放筒装载有开伞控制组件,通过气压计和IMU传感器采集气压高度、姿态、加速度等信息综合判断投放状态,并通过延时或控制气压高度下降量控制开伞,可确保投放筒与载机充分安全分离;开伞过程先由伞舱盖拉出引导伞,再由引导伞拉出主伞实现开伞,可提高开伞成功率。
