Abstract

In this work, a manufacturing and structural test of 1kW class horizontal axis wind turbine blade using natural-fiber composite was performed. The aerodynamic design of blade was performed after investigation on design requirement. The structural design load was investigated after aerodynamic design of blade. And also, structural design of blade was carried out. The structural design of blade was carried out using the simplified methods such as the netting rule and the rule of mixture applied to composite. The structural safety of the designed blade structure is investigated through the various load cases, stress, deformation and buckling analyses using the FEM method. Finally, the blade manufacturing and structural test using natural composite was carried out.

본 연구에서는 자연섬유 복합재료를 적용하여 1kW급 수평축 소형 풍력 발전 시스템 블레이드의 제작과 구조 시험 연구를 수행하였다. 블레이드의 설계 요구 조건을 분석하여 공력 설계를 수행하였다. 공력 설계 이후 구조 설계 하중을 도출하고 블레이드의 구조 설계를 수행하였다. 블레이드의 구조 설계기법은 복합재료를 적용한 단순 설계 기법과 혼합 설계 기법을 적용하였다. 설계된 블레이드의 구조 안전성은 다양한 하중조건, 변위, 좌굴 등의 해석을 위해 유한요소기법으로 분석하였다. 최종 자연 섬유를 적용한 블레이들 제작하였으며, 구조 시험을 수행하였다.
