The invention discloses a pneumatic ejection device and a method thereof. The pneumatic ejection device comprises a linear yin-yang ejection groove rail chain device and an inflatable wire drawing cloth ejection device, wherein the linear yin-yang ejection groove rail chain device is composed of yin-yang groove rails, an ejection push plate, an ejection chain and an ejection connecting device; the inflatable wire drawing cloth ejection device is composed of inflatable wire drawing cloth, a carrying shaft, a lifting platform and a wind tunnel air source device; under the air pressure effect of a wind tunnel air source, the section thrust of the inflatable wiredrawing cloth pushes a projected object, and the length direction of the orderly folded inflatable wiredrawing cloth restricts forward extension of airflow in a plate-shaped manner, so that the projected object obtains an ejection speed; the inflatable wiredrawing cloth pushes the ejection push plate and the ejection chain, the ejection chain converts thrust from the back face of the female-male groove rail to the front face of the female-male groove rail through the female-male groove rail, and the ejection connecting device pushes a projected object. The defects of an existing aircraft carrier catapulting device can be overcome, a ski-jump aircraft carrier can be provided with a catapulting boosting device, and a related universal missile catapulting frame can achieve cold catapulting and hot catapulting of various types of missiles; the structure is simple and practical, performance is excellent, and cost is low.

    本发明公开了一种气动弹射装置及其方法,包括阴阳槽轨、弹射推板、弹射链、弹射连接装置构成的直线型阴阳弹射槽轨链装置和充气拉丝布、担轴、升降平台、风洞气源装置构成的充气拉丝布弹射装置;在风洞气源气压作用下,充气拉丝布截面推力推动被投射物,有序折叠的充气拉丝布长度方向以板状方式约束气流向前伸展,使得被投射物获得弹射速度;充气拉丝布推动弹射推板和弹射链,弹射链通过阴阳槽轨将推力从阴阳槽轨背面转换到正面,弹射连接装置推动被投射物;本发明能改善现行航母弹射装置的弊端,能使滑跃式航母配置弹射助推装置,相关的通用型导弹弹射架能够实现各型导弹的冷弹射和热发射;结构简单、实用,性能优越,造价经济。
