翼身对接误差分析和工艺方案选择

Joint Error Analysis of Airfoil and Airframe and Process Program Selection

目前国内大型飞机项目研制采用“主制造商–供应商”模式:机体各部件制造由不同的机体供应商完成,机身结构集成由主制造商完成。项目研制阶段,在“主–供”模式下,针对机身、机翼三叉耳对两叉耳加衬套再由螺栓进行固定的连接结构方案,采用机体供应商加工到最终状态交付后对接和留工艺余量在总装型架上对接后精加工至最终尺寸这两种形式,决定了是否能够高质量、高效率、低成本地完成研制批飞机的制造,并保证设计要求的实现和满足飞机适航符合性要求。

At present the“main manufacturer–supplier”model is used widely for the research of large aircraft project inland:namely the airframe components will be manufactured by different airframe suppliers and assembled by main manufacturer.In project research stage,the joint method is matching the joint butts of airframe and airfoil and fasten by bolts,the methods of matching the components after delivery in final state and finishing the final dimensions after joint are adopted,which decides whether the aircraft batch production could be finished with high quality,high efficiency and low cost,and ensure to realize the design requirements and meet airworthiness requirements.
