飞航导弹(西方统称巡航导弹),是一种以火箭发动机或吸气式发动机为动力,装有战斗部、自控飞行的作战武器。“飞航”是指导弹在大气层内升力与重力、推力与阻力大致平衡的条件下,以某一较经济或特定的高度和速度进行飞行的方式。 Air-to-air missiles (collectively referred to as the West’s cruise missiles) are a kind of combat weapons that are powered by rocket engines or aspirated engines and are equipped with warheads and self-piloted flights. “Air Navigation” refers to the way in which a missile can fly at a relatively economical or specific altitude and speed under conditions of roughly balanced lift and gravity, thrust and resistance in the atmosphere.
