基于CAIV的航空发动机性能与费用的综合权衡模型框架

运用"费用作为独立变量"方法, 对航空发动机立项论证中的性能与费用的综合权衡与决策方法进行了研究.首先建立了航空发动机总拥有费用的参数估算模型, 研究了发动机主要性能参数与其主要设计参数之间的关系并建立了性能模型.然后研究了如何确定设计参数的约束条件即"权衡空间".最后将以上研究成果进行了综合, 建立了发动机性能与总拥有费用的综合权衡模型框架, 可用于发动机的设计参数与费用的决策. 

Aircraft engine performance-cost tradeoff model framework based-on CAIV

A study on aircraft engine performance-cost tradeoffs and decision-making method was made in application of CAIV(Cost as an independent variable) method.An engine parametric-cost-estimating model was brought forward,and then an analysis was made on the relationship between performances and parameters,and an engine performance model was built.Thereafter,the research was focused on how to define the constraint of parameter alternatives.Finally,by integrating all above studies,an aircraft engine performance-cost tradeoff model framework was built to assist decision making of parameters targets and total ownership cost goal.
