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。
Aiming at the problems that the integrated air-propeller system caused by the integrated design of the engine / projectile structure can not achieve the assembly, the structural size is too large, the resistance of the whole block increases and the impact environment of the steering gear is harsh, a split air-propeller program is proposed. Support stiffness, transmission stiffness, bearing overload and preload design and test verification work to solve the design and assembly of small-size rudder system, effectively reducing the overall resistance and rudder impact load system. The experimental results show that compared with the traditional integral air-rudder scheme, the indexes of the split air rudder scheme meet the requirements, greatly improving the flexibility of the air-rudder system design and providing a new idea for the design of the air rudder system.
