某飞机零批试制加工增重分析

本文根据某飞机生产试制中首批3架飞机空机理论重量和实际重量分别按零件分类和所属专业的统计比较,提出了控制飞机加工增重的重点部件(或专业)和主要零件,对造成加工增重的原因进行了探讨。

THE ANALYSIS OF THE PROCESSING INCREASED WEIGHT FOR PILOT PRODUCTION OF F-X AIRCRAFT

Weight incremem during aircraft preproduetion is a popular problem and attracts more rnanufaetures's atten(?) Based on statistical analysis of calculated and actual weights for the pans of three F X prototype empty aircraft in their manufacture's classificatio and specjalitics. the critieal componenis controlling weight increment of aircraft arc presented, that is amframe structure espeeially fpselage and wing- From the view of part's classification they are mainly some rnachined. sheet. metal and casting pans and cable. The main reason of weight increasing in airera(?) peroduetionction is that the dimension of most produets, is in the seo; e ot their upper (?)aace. but the noimmal sizes are usually used in the weight calculation. In addition, poor weight consciousness of some workers is an unneghgible faetor, for examDe. over tolerance (?)in some non malehing. parts.
