The invention discloses a pneumatic fire extinguishing bomb launching mechanism, device and method.The pneumatic fire extinguishing bomb launching mechanism comprises a launching cylinder, an end cover is arranged at one end of the launching cylinder, a launching opening is formed in the other end of the launching cylinder, a gas generation chamber is arranged in the launching cylinder, and a buffer cavity is formed between the gas generation chamber and the end cover; a bomb loading cavity is formed between the gas generating chamber and the launching port, the gas generating chamber is communicated with the buffer cavity and the bomb loading cavity, and a first buffer piece is arranged in the buffer cavity; an equipment cover is arranged on the upper portion of the launching barrel, an equipment cavity is formed between the launching barrel and the equipment cover, a buffering channel is formed between the equipment cavity and the buffering cavity, a sealing piece is arranged on the first buffering piece and tightly attached to the barrel wall of the launching barrel, and a linkage piece is arranged in the equipment cavity. The recoil force generated when the fire extinguishing bomb is launched is buffered through synchronous reverse counter weight according to the automatic balance principle, and the influence of the recoil force generated when the fire extinguishing bomb is launched on the stability of the aircraft can be greatly reduced.

    本发明公开了一种灭火弹气动发射机构、装置及方法,其中灭火弹气动发射机构包括发射筒,发射筒一端设置有端盖,发射筒另一端设置有发射口,发射筒内设置有气体发生室,气体发生室与端盖之间形成缓冲腔,气体发生室与发射口之间形成装弹腔,气体发生室分别与缓冲腔和装弹腔相连通,缓冲腔内设置有第一缓冲件;发射筒上部设置有设备罩,发射筒与设备罩之间形成设备腔,设备腔与缓冲腔之间形成缓冲通道,第一缓冲件上设置有密封件,密封件紧贴设置发射筒筒壁上,设备腔内设置有联动件。通过平衡自动原理同步反向配重来缓冲灭火弹发射时产生的后坐力,可极大降低灭火弹发射时产生的后坐力对飞行器稳定性的影响。
