The invention discloses a helicopter fire-fighting machine gun and ammunition matched with the helicopter fire-fighting machine gun for use, which are used for emergency rescue of trapped persons in high-rise fire in urban communities. The core of the fire-fighting machine gun is a motor disc 1, an ammunition clamping device 2 and a launching controller 4; wherein the motor disc 1 rotates around afixed shaft o at a high speed to drive the N ammunition clamping devices 2 which are located on the disc edge and evenly distributed in the circumferential direction to rotate at a high speed to obtain kinetic energy, the launching controller 4 selects the ammunition clamping devices 2 to be launched and sends release signals to the ammunition clamping devices 2 selectively, and the ammunition clamping devices 2 generate release actions to throw out ammunition; wherein the ammunition fire extinguishing bomb 20, the oxygen inhalation bomb 21, the gas filtering bomb 22, the window breaking bomb23 and the rigging bomb 24 are used in cooperation. According to the fire extinguishing machine gun, the mechanical emission technology is adopted, the application of the electronic control technology is combined, continuous and quick casting is conducted after rotating disc acceleration, a large number of fire extinguishing materials can be cast into a fixed point area in a short time, recoil force is avoided, and stability of a helicopter is not affected; the ammunition provided by the invention is low in cost and good in modularization degree, and only needs to be operated by one person.
本发明公开了一种直升机消防机枪及其配套使用的弹药,用于城市小区高楼火灾受困人员的紧急救援,消防机枪的核心是电机盘1、夹弹器2、发射控制器4;电机盘1围绕固定轴o高速转动,带动位于盘沿上的N个周向均布的夹弹器2高速旋转以获得动能,发射控制器4选择待发射的夹弹器2并择机向其发送释放信号,夹弹器2产生释放动作把弹药抛射出去;配套使用的弹药灭火弹20、氧吸弹21,滤气弹22,破窗弹23,索具弹24;本发明的消防机枪灭火机枪采用机械发射技术,结合电子控制技术的运用,在转盘加速后连续快速抛射,短期内可向定点区域抛投大量的灭火材料,没有后坐力,不影响直升机稳定;本发明提供弹药成本低,模块化程度好,仅需要一人操作。
