面向核心机单元体独立交付的总体结构设计

面向航空发动机核心机单元体的独立交付需求,基于核心机单元体的总体结构设计实践,从机匣同轴度、转子动平衡、接口控制、包装运输、验收交付5个方面对相关设计内容进行了总结。在此基础上,提出了可独立交付核心机单元体的总体结构设计原则:通过优化机匣结构设计和控制加工精度保证机匣同轴度;通过分级平衡设计、联轴器结构设计和平衡精度设计保证转子动平衡结果的可靠性和稳定性;通过接口控制、包装运输和验收交付过程控制,保证单元体的接口通用性、转运安全性和交付质量受控。

A general structural design oriented to the individual delivery in core engine module

Oriented to the requirements of the individual delivery in aircraft core engine module,the de⁃signs are summarized from case coaxiality,rotor dynamic balance,interface control,package and transporta⁃tion along with acceptance and delivery based on the general structural design practice of a certain core en⁃gine module.The design principles were concluded that the case coaxiality should be guaranteed by modify⁃ing case structural design and controlling case machining accuracy,the reliability and stability of rotor dy⁃namic balance should be guaranteed by designs of classification balance,coupling and balance precision,and interface generality,transport security and delivery quality-controlled should be guaranteed by inter⁃face control,package and transport designs as well as acceptance and delivery process-controlled,so as to ensure the design target of the individual delivery in core engine module.
