The invention relates to a high-low pressure chamber folding wing unmanned aerial vehicle ejection test device based on gas fuel. Comprising a launching cylinder outer cylinder, a launching cylinder end cover, a high-pressure chamber, a launching load assembly, a pneumatic assembly, an ignition assembly, a gas film assembly, a testing assembly and a fixing and positioning assembly. An inner connecting ring and an outer connecting ring are arranged on the launching cylinder end cover, the launching cylinder end cover is connected with the launching cylinder outer cylinder through the outer connecting ring and connected with one end of the high-pressure chamber through the inner connecting ring, the other end of the high-pressure chamber is a throat part, an air film assembly is arranged at a port of the throat part, and a check block used for limiting the bullet support is arranged on the inner wall of the launching cylinder outer cylinder. And a low-pressure chamber is formed among the high-pressure chamber, the launching cylinder outer cylinder and the bullet support. Initiating explosive devices such as propellant powder are replaced with gas fuel, and the application range is wider; large overload, impact damage and high-temperature damage of high-temperature and high-pressure gas to the unmanned aerial vehicle are reduced through the high-pressure chamber and the low-pressure chamber.

    本发明为一种基于气体燃料的高低压室折叠翼无人机弹射试验装置。包括发射筒外筒,发射筒端盖,高压室,发射载荷组件,气动组件,点火组件,气膜组件,测试组件和固定定位组件;发射筒端盖上设有内、外连接圈,通过外连接圈和发射筒外筒连接,通过内连接圈和高压室一端连接,高压室另一端为喉部,喉部端口设有气膜组件,发射筒外筒内壁设有用于对弹托进行限位的挡块,高压室外、发射筒外筒内与弹托之间形成低压室。本发明通过气体燃料代替发射药等火工品,适用范围更广;通过高、低压室降低高温、高压气体对无人机的大过载、冲击损伤、高温损伤。
