美国空军对今后的近程空-空导弹的要求,是显著地提高其机动能力和增加精度。目前许多导弹设计的特点,是具有十字形的弹体结构并采用侧滑转弯(STT)控制。由于空气动力效应低,这种设计不可能满足上述要求。采用倾斜转弯(BTT)的方式控制,能够设计出气动特性最佳的弹体,因而能达到近程空-空导弹(SRAAM)的机动性和精度的要求。此外它还具有另外的一些优点,从而能提高整个导弹的可控性,诸如: 纵向攻角小(α≤14°) 法向加速度高(100g) 侧滑角小(β≤3°) 诱导滚转力矩最小空军装备试验室已经着手用FY76研究在近程空—空导弹上应用倾斜转弯操纵的技术。由于效果良好,这项努力一直在继续进行。BTT的概念,在FY78上将通过回路试验的硬设备进一步得到验证。
The requirements of the United States Air Force for future short-range air-to-air missiles are to significantly increase its mobility and accuracy. Many of the current missile designs feature a cruciform projectile structure with side-to-side turning (STT) control. Due to the low aerodynamic effect, this design can not meet the above requirements. Tilt-turn control (BTT) enables the design of projectiles with the best aerodynamics to achieve the maneuverability and accuracy of short-range air-to-air missiles (SRAAMs). In addition, it also has other advantages, which can improve the controllability of the entire missile, such as: longitudinal angle of attack small (α ≤ 14 °) high normal acceleration (100g) small side slip angle (β ≤ 3 °) induced roll Minimizing torque The Air Force’s equipment laboratory has begun using FY76 to study the technique of using pitch bend maneuvering on short-range air-to-air missiles. Thanks to good results, this effort has continued. The concept of BTT was further validated on the FY78 by hardware testing of the loop test.
