Advanced configuration generation technique for the complex aircraft geometry

This paper presents the configuration design method for a parameter-based geometry representation and the aircraft complex configurations generation using a component-based approach. The algorithm is based on shape functions to keep the modified geometry smooth and to represent complex curve shapes with small number of control variables. This method can be especially effective and efficient when small changes in local geometry are required. Controlling the shapes becomes also much easier because these shapes are represented in non-dimensional design space and with polynomials. Representation of curves with two or more control parameters allows generating three dimensional surfaces with few control parameters, which is advantage of this method. Implementation of this approach can be very useful for the issues in design optimization and computational fluid dynamics (CFD) problems, such as, smooth aircraft parts surface generation, fuselage, or wing surface representation. The accuracy between the shapes generated using proposed method and initially given shapes are compared and analyzed. Hence, the efficiency of the method is demonstrated.
