摘　　要：高层建筑消防炮主要是为应对高层火灾而研制的一种消防设备.高层建筑消防炮采用气动方式实施远距离发射,灭火弹出膛后在空中自由飞行直至侵彻建筑物玻璃进入火场后起爆灭火.基于高层建筑灭火炮的工作特点,研究了灭火弹在诸力作用下的运动规律,建立了弹道数学模型,结合算例进行了求解.弹道模型主要描述了内弹道过程、标准外弹道分析和非标准气象条件下的外弹道过程.根据所得弹道诸元编制了射表,确定了射表搜索策略,为消防炮控制提供了必要参数.A fire extinguishing cannon is fire-fighting equipment developed for fighting against high-rise building fires.The remote launching process of the high-rise building fire extinguishing cannon is fulfilled by pneumatic means.The shell will fly freely in the air after launching until impacting the glass of building,the fire fighting process will be carried out then at the fire field.The motion law of the shell in conditions of different forces was analyzed based on the working characteristic of the fire extinguishing cannon,mathematical models of ballistics,which were involved with the interior ballistic in the process of launching and the exterior ballistics analysis in the state of the standard and nonstandard weather conditions,were established and solved by combining a numerical example.A firing table and a search strategy aiming at the table were compiled based on the trajectory data obtained,which provide the cannon＇s control with the necessary parameters.
