【摘要】 根据飞机设计要求来选择主要参数往往涉及许多不确定的因素。本文基于多层神经网络计算模型 ,提出了一种新的飞机主要参数的估算方法 ,并给出了实现这种方法的详细步骤。将该方法应用于喷气支线飞机和喷气公务机主要参数的估算 ,测试结果表明估算误差均在 1 0 %之内。更多还原

【Abstract】 The preliminary sizing of aircraft is a difficult task due to the uncertainties involved in the process of the sizing. A new approach is proposed for the preliminary sizing of aircraft based on the computational model of neural network. The approach is applied to the preliminary sizing of regional transport jets and business jets. Experimental results show that the estimation error for both cases is less than 10%. This new approach is an effective way to the preliminary sizing of aircraft.更多还原
