针对不同质量战斗部的防空导弹弹族设计

Design of Air-Defense Missile Familization with Specified Warheads

以Aster-15/30导弹为基准,研究了战斗部质量不同情况下组成中近程防空导弹与中远程防空导弹弹族的设计流程。首先对具有15 kg战斗部的Aster主级以及Aster-15/30导弹对应的中近程、中远程助推器进行反设计。然后分析了无量纲外形不变,保持侧喷发动机、巡航发动机能力与Aster主级相同,战斗部质量增加时的主级设计流程,设计具有30/50 kg战斗部的主级。接下来分析助推器设计流程,设计使30/50 kg战斗部的主级具有与Aster-15/30导弹相同的末段机动能力的助推器。最后,通过弹道仿真检验了设计的合理性。

Aster-15/30 missiles are chosen as the baseline, and how to design darts with specified war head and a set of boosters are studied to form a family of short-range air-defense missiles and long-range air-defense missiles. A reverse design research on the darts and boosters of Aster-15 and Aster-30 missiles is taken. The design flow of darts with the same no-dimensional shape, same lateral jet capability and same cruise engine capability of Aster dart is specified while the mass of warhead is specified. And a dart with 30 kg warhead and a dart with 50 kg warhead are designed. The methods to design boosters with specified darts to form long-range and short-range air-defense missiles are figured out, and a trajectory simulation is employed to confirm the validity of design.
