目前,在火炮设计与勤务使用中,迫切需要一种予计炮口冲击波超压的计算方法,尤其是绘出炮四周围空间直至炮手区域的冲击波超压的等压场。因为,只有完整的等压场才能分析与予计炮口制退器的影响并确定危险区域的范围。 由于带炮口制退器的出口气流之准确计算极为复杂,尚无一种可供计算的成熟方法。近年来,国外推荐的是半经验方法,如美陆军“工程设计手册”方法、美AD601728方法及苏奥尔洛夫方法等。由于这些方法的经验性质,因此,对不同类型火炮、不 At present, in artillery design and service use, there is an urgent need for a method of calculating the overpressure of the muzzle shock wave, in particular, the isostatic pressure field of the shock wave overpressure plotting the space around the gun to the gunner’s area. Because only a complete isobaric field can analyze and predict the effects of a muzzle brake and determine the extent of the hazardous area. Due to the extremely complex calculation of the outlet airflow with the muzzle brake, there is no proven method for calculation. In recent years, foreign recommended semi-empirical methods, such as the US Army “Engineering Design Manual” method, the United States AD601728 method and the method of Ororov and so on. Due to the empirical nature of these methods, therefore, for different types of artillery, no
