航空绞车尺寸链设计研究

作为航空器外挂物,航空绞车的工作安全性、灵活性、可靠性以及接口的尺寸匹配尤为重要。从使用方式和结构特点出发,运用符合国军标的通用设计形式和CAD软件,研究了航空绞车与飞机接口的外形尺寸容许范围,得到了其制造和装配尺寸链的最大公差。通过实际使用和试验检验表明,航空绞车完成了挂机带飞,体现了较高的抗起降冲击性能。

Design of Size-chain for Reeling-machine

As an external store for an aircraft,the safety,flexibility,reliability and interface dimension matching of reeling-machine was especially important.From the use and structural characteristics,exterior dimension tolerance range of interface between the reeling-machine and aircraft was analyzed by the Chinese military standards and software of CAD,the maximum tolerance of size-chain for manufacture and assembly was obtained.The test shows that flying with reeling-machine is completed to reflect the high anti-landing impact performance.
