记:机炮口径多大合适?庆:火炮口径的确定需综合考虑武器的重量、体积、射速、炮弹初速与杀伤力等后确定。口径增加后,杀伤力会成倍增加。下图为25毫米与30毫米机炮对坦克装甲车辆及掩体内的人员进行一次齐射的杀伤概率比较。从图可以看出,25毫米炮弹需要两倍的数量才能达到30毫米炮弹的效果。战斗机的机炮口径,对空为主的一般为20毫米左右,对空对地兼顾的一般为20～25毫米,对地攻击为主特别是以对坦 Note: How much is the caliber of gun? Qing: artillery caliber to be determined by comprehensive consideration of the weight of the weapon, the volume, the rate of fire, the shell velocity and lethality determined. As the caliber increases, lethality multiplies. The figure below shows the probability of a 25-mm and 30-mm cannon firing a volley of tanks and armored vehicles in a salvo. As can be seen from the figure, a 25-mm artillery shell needs twice as many numbers to achieve the effect of a 30-mm artillery shell. Fighter jets caliber, mainly air-based about 20 mm, air and ground to take into account the general is 20 to 25 mm, mainly to the ground attack, especially against the tank
