针对新机研发之初,在仅有飞机初步方案而需预测飞机制造工时定额的实际情况,提出用重量法和参数方程法测算首架飞机制造工时定额,并以此为基础,利用熟练曲线推算试制批和批生产工时定额的方法。文章对测算首架飞机制造工时的国外三种参数法方程,应用于我国飞机研制实践的可行性进行了验算分析,同时,在收集国内飞机制造工时定额基础上,经回归得出我们自己的测算首架飞机制造工时定额的参数方程,可供飞机设计、工艺和工时定额管理人员试用。
In the light of the actual situation of only the initial plan of the aircraft and the forecast of the man-hours fixed by the aircraft, aiming at the actual situation of only the initial plan of the aircraft, a weight scale method and a parametric equation method are proposed to measure the first man-hours fixed by the aircraft. Based on this, Trial batch and batch production hours fixed method. This article has carried on the checking analysis to the feasibility of measuring the first time of aircraft manufacturing man-hour abroad three kinds of parameter equations, which is applied to the development of the aircraft in our country. At the same time, on the basis of collecting the fixed-time of the domestic aircraft manufacturing, The first aircraft to create a fixed-time parametric equation for aircraft design, process and time quota management trial.
