军用飞机总体方案的可承受性分析

为了研究飞机设计中的不确定性因素对总体方案优劣的影响,对飞机设计中不确定因素的存在根源进行了分析;介绍了不同不确定性因素的相应处理方法,包括概率论、变复杂度理论等;以此为基础,提出了面向可承受性的飞机总体方案评估方法;采用该总体方案评估方法,对某军用飞机及其改型的可承受性进行了分析;通过计算可知,在改型飞机上加装新型空空导弹可使改型飞机的可承受性优于原型机;结果表明,该方法可以应用于飞机总体方案的有效评估和合理改进中。

The Affordability Analysis of Military Aircraft Conceptual/Preliminary Scheme

In order to investigate the influences of uncertain factors to the quality of a militzry aircraft conceptual/preliminary scheme,roots of the uncertain factors in aircraft design process were analyzed.Corresponding disposal methods of uncertain factors were introduced,including the probability,varying complexity theory and so on.Based on the above efforts,the affordability oriented assessing method of aircraft collectivity scheme was proposed.Using this method,the affordability of a certain military aircraft and its remodelment were analyzed.Calculations showed that a new type air to air missile installing on the remodeled military aircraft could get a better affordability than its prototype.These results indicated that affordability oriented assessing method was competent for using in availability assessing and reasonable ameliorating of an aircraft conceptual/preliminary scheme.
