Abstract

This paper is concerned on the generation of an optimal section of wing in ground effect by a SQP method which is one of nonlinear optimization techniques. A potential panel method is used for the flow analysis and the ground effect is taken into account by an image method. The numerical method is first verified by an inverse problem where a shape of wing section is sought for the prescribed pressure distribution. The purpose of the present paper is to generate a wing section which can give a maximum lift subjected to the design constraints including the height stability which is important in the WIG design. The effect of the tail wing is also included.

본 논문은 비선형 계획법의 하나인 SQP법을 이용한 지면(혹은 해면)효과를 받는 익형(WIG)의 최적단면생성에 관한 연구 결과이다. 유동장의 해석기법으로는 포텐셜패널법을 사용하였고, 지면효과는 경상법(image method)을 사용하여 처리하였다. 수치계산의 검증을 위하여 이미 알려진 날개단면의 압력분포를 주고 그 단면을 역으로 찾아가도록(역해법) 하였다. 본 논문의 목적은 주어진 구속조건(설계조건)중 특히 WIG선에서 중요한 종방향 안정성을 만족하면서 최대양력을 주는 익형의 단면을 생성하는 것이며 꼬리날개의 영향을 고려하였다.
