民用直升机费效综合分析方法研究

Comprehensive Analysis of The Cost-effectiveness for Civil Helicopters

采用工程类比法和参数法相结合的方法建立了民用直升机研制费、生产成本和直接使用成本的估算模型,并对某型直升机的直接使用成本进行了估算,估算结果符合目前国内外民用直升机的普遍规律。结合座公里因素,开发了基于能力的直升机费效综合分析模型,并将某型国产直升机的经济性与国内外竞争机型进行了对比分析。结果表明,该分析模型适用于民用直升机使用经济性的快速评估。

Using engineering analogy method and parameter method to establish a civilian helicopter development, production and direct operating cost assessment model, and the direct operating cost of one civil helicopter had been estimated. The result accorded with the common rule of civil helicopters at home and abroad. Combined with seat kilometers factors, developed helicopter cost-effective analysis model based on a comprehensive capabilities. And the economical efifcience of a certain domestic helicopter was comparative analysis with competition models. The results show that the model can be applied to rapid assessment the civil helicopters’ use economy.
