Abstract

Propeller performance measurement system for commercial propeller was designed and applied to the wind tunnel test for 3 commercial propeller models with diameters of 30 inch. The thrust and torque of the propeller was directly measured by using 6-components balance installed on the rotating axis. The measurement system was validated by using wind tunnel balance calibration equipment. Propeller test stand including measurement and rotating system was validated by using QTP propeller. In the hovering condition, we compared the performance test results and the specifications of the commercial propeller provided by the manufacturer and confirmed that there are differences in the thrust and the torque. We measured the propeller performance with various wind speeds, propeller models and angles of attack and was summarized by thrust coefficients. We confirmed that the trend of the thrust coefficients was different in the low angle of attack and high angle of attack. An aerodynamics database that can be used for future aerodynamic design of an unmanned aerial vehicle was secured.

상용 프로펠러의 추력과 토크를 측정하기 위한 성능시험 장치를 고안하였으며, 30인치급 3가지 프로펠러에 대한 성능시험을 수행하였다. 프로펠러 추력과 토크 측정을 위해 모터, 프로펠러와 연결된 6분력 발란스를 적용하였으며, 풍동 저울 교정 장비를 이용하여 측정 시스템의 확인을 수행하였으며, QTP 프로펠러를 적용하여 구축한 성능시험 장치의 검증 시험도 수행하였다. 제자리 비행 조건에서 상용 프로펠러의 제작사에서 제공하는 사양과 시험 결과를 비교하였으며, 추력 및 토크에서 차이가 있음을 확인하였다. 받음각, 프로펠러 형상, 풍속을 변경시켜가며 프로펠러 성능을 측정하였으며, 각 프로펠러에 대해 RPM에 따른 프로펠러 추력 계수로 나타내었다. 저 받음각과 고 받음각에서 경향이 다르게 나타남을 확인하였으며, 차후 공중용 무인이동체 공력 설계에 활용 가능한 공력 데이터베이스를 확보하였다.
