歼击机的主要任务是与敌机展开空战,击落敌机,保衛自己領空的安全和夺取制空权。歼击机上装有几門炮,炮口永远朝着前面,不能上下左右轉动。歼击机上只有一个飞行員,他也就是射击員。在空战中,飞行員为了改变炮口的方向,把炮口瞄准敌机,必須不断地操縱飞机轉动。从这个角度来看,所謂歼击机的空战射击,实际上就等于飞行員在操縱着几門会飞的炮,在空中与敌机展开战斗。最主要的問题空战射击中最主要的問題就是瞄准問題。炮弹运动的軌迹叫做弹道。瞄准的目的就是使弹道通过目标。弹道、武器和目标三者之間的关系位置,我們可以用点、线、角这些条件来确定(圖1)。通过炮口的水平面叫做 The main task of the fighter plane is to launch an air war with the enemy aircraft, shoot down enemy aircraft, defend the security of their own airspace and seize the air supremacy. There are several guns on the fighter plane, and the muzzle is always facing the front and cannot be turned up or down. There is only one pilot on the fighter plane. He is also a shooter. In the air battle, in order to change the direction of the muzzle, the pilot aimed the muzzle at the enemy aircraft and must constantly manipulate the rotation of the aircraft. From this point of view, the so-called air-to-air combat of a fighter plane is actually equivalent to the fact that the pilot is manipulating several cannons that can fly and fight against enemy aircraft in the air. The most important issue is that the most important issue in air combat shooting is targeting. The trajectory of artillery shells is called ballistic. The aim is to make the trajectory pass the target. The position of the relationship between the ballistics, the weapon and the target can be determined by the conditions of point, line and angle (Figure 1). The level through the muzzle is called
