Parametric modeling and optimization of low observability fuselage in aircraft conceptual design
-
摘要: 为提高低可探测机身外形造型效率,在概念设计中针对典型机身剖面研究了参数化造型方法.定义了若干设计参数对B样条的控制顶点进行调整,从而用单条B样条表示出机身和座舱盖的典型剖面,包括尖劈及凹凸曲线等.以此为基础,构造了一系列参数化剖面曲线模板,调整选用模板的参数生成机身各站位处外形,从而实现了机身快速造型.最后,利用提出的方法建立了两种隐身飞机概念方案的外形,并以侧向雷达散射截面为目标分别进行了优化,验证了该方法在机身外形优化中的有效性.Abstract: Parametric modeling method on typical sections of fuselages was studied to improve the efficiency of low observability fuselage modeling in aircraft conceptual design. Several design parameters of section curves were defined to adjust the control points of B-spline, and then typical sections of fuselage and canopy were described with single B-spline, including cutting edge, concave-convex curves, etc. Based on this method, a series of parametric templates on section curves were created. When the parameters of selected templates had been set, the practical shape of the cross section was obtained at each station, and then a low observability fuselage can be constructed rapidly. Finally, two low observability design concept models were generated to apply the proposed method, and optimized with the objective of minimal lateral radar cross section, which validated the effectiveness of fuselage optimization with parametric modeling method.
