The invention discloses a loading posture adjusting device of a small aircraft, which relates to the field of aircrafts and comprises a posture adjusting parachute, a connecting rope, a mounting cabin, a snapping rope and a dividing assembly, the posture of the aircraft is adjusted through the posture adjusting parachute, a connecting rope between the posture adjusting parachute and the cabin body is cut regularly in combination with the segmentation assembly, and finally, after posture adjustment is completed, the aircraft enters a certain height again, as the height is reduced, the air density is increased, the flying speed is increased, and the dynamic pressure of the posture adjusting umbrella is increased, when the pulling force formed by the dynamic pressure exceeds the design value of the snapping rope, the cabin body and the attitude adjusting parachute are disconnected through the snapping rope, the aircraft reenters due to inertia, attitude adjusting control over the aircraft is completed, and the device is simple in structure, low in cost and small in needed space size; moreover, the device does not need extra energy requirements such as power supply, can complete all sequential actions from parachute opening, posture adjustment to separation, can effectively reduce the flight attack angle of the aircraft in the reentry process, and provides a simple, reliable and economical technical method for reentry posture adjustment of a small aircraft.
本发明公开了小型飞行器的载入调姿装置,涉及飞行器领域,包括调姿伞、连接绳、安装舱、拉断绳和分割组件;通过调姿伞调整飞行器的姿态,并结合分割组件定时切割调姿伞和舱体之间的连接绳,最后调姿完成后飞行器再入到一定高度后,随着高度降低,空气密度增大飞行速度变大,调姿伞的动压增加,当动压形成的拉力超出拉断绳设计值时,拉断绳断开舱体和调姿伞之间的连接,飞行器惯性再入,完成飞行器的调姿控制,该装置结构简单成本较低,所需空间体积较小;且装置不需要额外的供电等能源要求,自身能够完成从开伞、调姿到分离的全部时序动作,能有效减小飞行器再入过程中的飞行攻角,为小型飞行器的再入调姿提供简单、可靠、经济的技术方法。
