我国民用支线飞机技术水平的测度分析

为了定量研究我国民用飞机技术水平与世界先进水平的差距,从安全性、经济性与舒适性三方面出发,构建民用支线飞机技术水平的测度指标体系。以各个时期世界典型支线飞机数据为样本,采用回归分析法,利用SPSS软件建立支线飞机技术水平的测度模型。以我国典型支线飞机性能数据为基础,根据此测度模型,对我国民用支线飞机技术水平进行定量研究。结果表明:我国民用支线飞机Y7-100的综合技术水平落后同期世界先进水平10.22年,ARJ21-700落后7.83年;我国民用飞机技术水平已有明显提高,与世界支线飞机先进水平的差距在缩小。

Measure Analysis of the Technical Level of Civil Regional Aircraft in Our Country

From three aspects as safety, economy and comfort, build the measure index system of the technical level of the civil regional aircraft. Took the date of typical regional aircraft in the world as samples, used regression analysis method and founded a measure model to measure the technical level of civil regional aircraft in the world. Then, on the basis of the performance data of Chinese typical regional aircraft, using the measure model, analyzing the technical level of civil regional aircraft in our country. Found that the comprehensive technology level of Our country civil regional aircraft Y7-100 behind the world"s advanced level in the same period for 10.22 years, the comprehensive technology level of ARJ21-700 behind the world"s advanced level in the same period for 7.83 years and so on. Civil aircraft technical level has been improved obviously in our country, and the gaps in civil regional aircraft between China and the world"s advanced level is shrinking.
