Abstract

本发明提供了一种面对称的高超声速飞行器的外形参数快速获取方法及系统，该方法包括获取飞行器模型，并对飞行器模型进行尺寸归一化处理获得标准归一化模型；根据飞行器对称面轮廓变化情况，通过测量软件确定各截面处轮廓变化剧烈的点的坐标，选择竖直划分飞行器截面个数及截面设置位置；根据截面设置位置及轮廓变化剧烈的点坐标，通过测量软件测量获得各截面到飞行器端头的距离，以及各截面处飞行器本体高度与宽度；测量两截面间的飞行器腹部与水平面形成的上抬角度数和飞行器后掠前缘相对截面迎风面底部的上抬高度；确定描述所述飞行器的外形参数的参数矩阵。该方法为飞行器气动力预测、飞行器气动性能评估及飞行器外形优化快速地提供参数依据。
