Abstract

In this study, CFD analysis for 2D ellipse and 3D CRW UAV are performed. Furthermore, flow analysis around a hub connecting body and rotor is analyzed and a strategy to reduce the drag caused by the hub is sought. Also, the idea of fairing installation is confirmed by a wind tunnel test.

본 논문에서는 CRW 무인 항공기에 사용되는 타원익형과 전기체의 공력해석 및 동체와 로터를 연결하는 허브주위의 공기역학적 현상에 대한 분석을 수행하였고 허브로 인한 항력 증가를 감소할 수 있는 방안을 모색하였다. 또한 항력 감소를 위해 제안한 fairing 장착방법을 풍동시험을 통해 그 효과를 확인하였다.
