Aircraft Combat Survivability Estimation and Synthetic Tradeoff Methods

A new concept is proposed that susceptibility, vulnerability, reliability, maintainability and supportability should be essential factors of aircraft combat survivability. A weight coefficient method and a synthetic method are proposed to estimate aircraft combat survivability based on the essential factors. Considering that it takes cost to enhance aircraft combat survivability, a synthetic tradeoff model between aircraft combat survivability and life cycle cost is built. The aircraft combat survivability estimation methods and synthetic tradeoff with a life cycle cost model will be helpful for aircraft combat survivability design and enhancement.

飞机概念设计中的生存力效益/代价综合评估方法

首先介绍了军用飞机在常规武器威胁下的生存力评估指标及几种提高生存力措施；其次研究了将全因素试验法应用于评价生存力提高措施对生存力评估指标的增益影响的可行性；最后基于飞机的安全性、维修性、可靠性、保障性、性能及费用等约束条件，建立了一种能应用全因素试验法在飞机概念设计中进行飞机生存力效益／代价综合评估的方法。算例初步说明了方法的有效性。

基于分层体系的现代作战飞机方案评估

针对目前作战飞机方案评估中体系与方法的不足,依据飞机发展的时序性和评估内容的细化程度,确定了现代作战飞机方案评估的5个层次,它们分别为综合作战能力层、综合作战效能层、综合使用效能层、综合使用效费层和方案评价决策层。在分析各评估层特性的基础上,建立了各评估层的细化指标体系,改进和完善了各评估层的理论模型和计算方法,通过现役先进作战飞机的算例验证了评估体系和方法的有效性。本文所建立的评估体系和方法可以为现代作战飞机以及其他武器系统的方案评估提供有益的参考和依据。
