A demonstration method on the design elements of a flight deck

[目的]为了解决航空母舰(简称“航母”)飞行甲板的主尺度要素设计问题,以航母舰体主尺度要素为输入,对飞行甲板主要设计要素进行论证,并开展相应的数学模型研究。[方法]通过解读分析13艘国外典型大、中型航母的各项设计参数,借助支持向量机回归(SVR)算法和径向基核函数(RBF)建立相应的回归分析模型,并采用模拟退火(SA)算法对部分计算参数进行优化以提高回归精度。以“肯尼迪”号常规动力航母作为检验样本、其余12艘航母作为训练样本集进行回归计算,验证该回归模型的预报效果。[结果]所得计算结果与“肯尼迪”号实际参数的对比显示,多数飞行甲板设计要素都具有较好的预报精度,同时,也得到了少数设计要素预报精度不高的原因。[结论]所做研究对航母飞行甲板总体设计具有技术支撑作用。

[Objectives]The idea of using the main dimensional factors of a carrier’ hull to demonstrate a flight deck’s primary design parameters and mathematical models was proposed.[Methods] After analyzing the design data of thirteen foreign large-middle sized aircraft carriers by virtue of the support vector machine regression(SVR) method and the RBF kernel function, the regression analysis model for predicting the flight deck’s primary design parameters was established, and the calculation arguments optimized by the simulated annealing(SA) algorithm to improve the precision of the regression. To examine the performance of the prediction model, the USS Kennedy(CV-67) was selected as the checking sample and the other twelve aircraft carriers as the training samples.[Results]By comparing the prediction model’s regression results with the actual design parameters of the USS Kennedy, it was found that the majority of the flight deck’s primary design parameters were excellent and precise predictions. On the other hand, the reasons for the few imprecise predictions were provided in detail.[Conclusions]The work in this paper provides the necessary technical support for the preliminary design of the aircraft carrier’s flight deck.
