The invention discloses a stratospheric airship with a pressure maintaining device. The stratospheric airship mainly comprises an airship main bag body, a nacelle, pressure adjusting air bags and a pressure maintaining module. A pressure regulating air bag structure is adopted, and the pressure maintaining module is controlled by the control system to regulate the pressure in the stratospheric airship bag body. A propelling device is mounted on the rear portion of the airship main bag body to provide power. A solar cell array is combined with an energy storage system to supply power. Meanwhile, a variable-pitch propeller is mounted at the head of the airship, so that the yawing and pitching postures of the airship are controlled at the same time, and double-margin control over yawing and pitching of the airship is jointly formed by the airship and the propelling device. The stratospheric airship effectively solves the problem that the stratospheric airship cannot maintain good appearance and keep constant pressure due to day and night temperature difference and gas leakage. The number and the positions of the pressure regulating air bags can be selected according to various factorssuch as air staying time and airship loads, and certain flexibility is achieved.

    本发明公开了一种含有保压装置的平流层飞艇,主要包括飞艇主囊体,吊舱、调压气囊与保压模块。采用调压气囊的结构,通过控制系统控制保压模块调节平流层飞艇囊体内压力。飞艇主囊体后部安装推进装置提供动力;由太阳能电池阵结合储能系统供电。同时飞艇头部安装变距螺旋桨,实现飞艇偏航及俯仰姿态的同时控制,与推进装置共同形成飞艇偏航和俯仰的双裕度控制。本发明有效解决了平流层飞艇因昼夜温差与气体泄露而无法维持良好外形,保持恒定压力的问题。本发明可根据驻空时间,飞艇载重等多种因素选取调压气囊个数、位置,具有一定的灵活性。
