摘　　要：研究一种可以在直升机总体方案设计阶段进行直接使用成本估算的方法。通过对通用型直升机样本数据资料的整理和回归分析,得到了用燃油消耗率和直接维护保障耗时率来衡量和估算直接使用成本大小的新方法,建立了通用型直升机直接使用成本的估算和比较模型,为通用型直升机总体设计阶段直接使用成本的评估提供了参考依据。In this paper, a new method, which was used to estimate the direct use cost during the integral design phase of helicopter, was proposed. Based on the sort and regression analysis to the sample data of utility helicopter, the new method, which was used to measure and estimate the di- rect use cost with the fuel consumption ratio and direct maintenance support time-consuming ratio, was derived, and the estimate and compared model for direct use cost of utility helicopter was also presented. The model could be referenced for the evaluation for the direct use cost for utility helicop- ter during the integral design phase.
