分体式空气舵系统结构设计及试验研究

Structure Design and Experiment Research on Separated Air-rudder

针对发动机/弹体结构一体化设计带来的整体式空气舵系统无法实现装配、结构尺寸过大导致全弹阻力增大及舵机冲击环境恶劣等问题,提出了分体式空气舵方案,开展了支撑刚度、传递刚度、轴承超载及预紧设计及试验验证等工作,解决了小尺寸舵系统设计及装配问题,有效降低了全弹阻力及舵系统冲击载荷。试验结果表明,与传统的整体式空气舵方案相比,分体式空气舵方案各项指标均满足要求,大大提高了空气舵系统设计的灵活性,提供了一种空气舵系统设计的新思路。

The separated air-rudder structure design is put forward under the condition that the unitary air-rudder structure could lead to assembly problem,as well as the aerodynamic drag and aggravating impact conditions. The support stiffness,transmission stiffness,bearing overload and preloaded design and experiments were carried out to solve the problem of small rudder system design and assembly,effectively reducing the resistance and the impact load. Experiment results show that compared with the traditional scheme of unitary air rudder,the separated air-rudder structure enhances the adaptability of air-rudder greatly,providing a new approach to design of air rudder system.
