Life Cycle Cost Analysis of Uninhabited Combat Air Vehicles

无人战斗机是当代一种新概念航空武器。基于文献上主流的无人战斗机概念和根据概念拟定的无人战斗机战技性能要求 ,完成了一个初步的无人战斗机方案设计。利用修正过的参数化费用模型对无人战斗机方案的全寿命周期费用进行了分析估算。所作设计方案和全寿命周期费用分析结果表明 ,无人战斗机与有人战斗机相比 。

The concept of UCAV (Uninhabited Combat Air Vehicle) is claimed to have made the cost of operation and support no longer the largest element in life cycle cost but no technical details are available in the open literature. We present the technical details of life cycle cost analysis of an uninhabited combat air vehicle; but such analysis is at the level of conceptual design previous to preliminary aircraft design. We assume the mission to be the suppression of enemy defenses. Section 1 discusses the differences between UCAV and manned combat air vehicle and then gives the conceptual design of our UCAV; Table 1 lists the initial sizing results of our UCAV and Table 2 lists its performance data. Section 2 discusses in much detail the modification of a parametric life cycle cost model for manned combat air vehicle to make it applicable to UCAV cost analysis. Numerical results show that the cost of operation and support is 40% and confirms preliminarily the claim that it is no longer the largest element in life cycle cost.
