Abstract

The analysis of aerodynamic characteristics for aircraft propellers is studied to develop high efficiency composite propellers. It is to verify the accuracy and reliability of predicting the efficiency characteristics of aircraft propellers by applying nonlinear numerical analysis. The numerical simulation method incorporated the CFD code, which is based on RANS (Reynolds Averaged Navier-Stocks) equation. The study includes a comparative analysis between the numerical simulation results and the wind tunnel test results of the full-scale aircraft propeller. The comparison shows that thrust and power coefficients of the propeller calculated by nonlinear numerical analysis are higher than those based on the results generated from the wind tunnel test. The efficiency of the propeller calculated by numerical analysis matches closely to the efficiency based on the wind tunnel test results. The verification results are analyzed, then, will be used in optimizing the design and manufacture of the subject aircraft propeller studied.

본 연구는 고효율 복합재 프로펠러를 개발하기 위하여, 항공기 프로펠러 효율 특성 해석을 수행하였다. 비선형 수치해석을 이용하여 프로펠러의 공력 특성을 분석하고, 풍동 실험결과와 비교 분석하였다. 유동해석코드는 비선형 유동방정식인 RANS(Reynolds Averaged Navier-Stocks)를 수치해석화한 코드를 사용하였다. 해석 결과, 수치해석을 통하여 얻어진 프로펠러의 추력 및 출력계수는 실험결과와 비교하여 다소 높게 분석되었으며, 추력과 출력의 비로부터 계산된 프로펠러 효율은 실험결과와 잘 부합하는 것으로 확인하였다.
