近距格斗空空导弹的归零时间设计

导轨式发射的空空导弹归零时间设计是系统总体设计的重要参数之一。特别是对于近距格斗导弹来说它不仅涉及载机的安全，还关系到导弹的作战效果。它的设计与载机的挂点位置、导轨的尺寸、发动机推力、发射装置的开锁力、发射架与导弹相对运动时的摩擦力以及导弹的阻力等密切相关，同时影响导弹的控制精度。针对以上特性进行系统综合分析与设计，提出归零时间的设计原则。

DESIGN OF ZERO TIME FOR SHORT-RANGE AIR-TO-AIR DOGFIGHT MISSILE

The zero time of rail-launched air-to-air missile is one of the important parameters in overall missile system design.It is especially important for short-range air-to-air dogfight missile because it has great bearing not only on safety of the carrying aircraft,but also on the missile's combating effect.The design of the zero time involves considerations of suspension point in the aircraft,fuselage dimensions,thrust of the rocket motor,unlocking force of the launcher,friction force of the missile moving on the launch rail,drag of the missile,etc.,and is also closely related to the control accuracy of the missile.In this paper,the foremen- tioned factors involved in zero time design are discussed and the design criteria of the zero time are developed.
