摘　　要：提出了一种伸缩舵面机动弹头气动布局设计的新理念,避免了普通全动舵面布局方案中舵轴设计面临的严峻热环境和力环境等问题.初步研究了采用这类设计理念的多种机动弹头布局的气动特性,分析了伸缩舵面机动弹头布局的稳定和操纵特性,对采用这种理念设计得到的一种机动弹头布局的机动性能进行了仿真.结果表明,新的机动弹头有较强的机动性,可通过机动飞行增大突破敌方导弹防御体系的概率,并能明显增加射程.A new kind of maneuvering warhead aerodynamic configuration with the use of two retractile control surfaces was proposed, which avoided such severely aerothermodynamic environment in reentry flying like traditional maneuvering warhead configuration. Many aerodynamic configurations of this kind of maneuvering warhead were studied, and the static stability and controlling stability of this new kind of maneuvering warhead were analyzed. The maneuvering capability was simulated. Result shows that compared with traditional maneuvering warhead aerodynamic configuration, the maneuvering warhead of the new kind of configuration has better maneuverability. By maneuver flight, the warhead can improve probability of breaching enemy＇s missile defense system, and the range can be extended.
