3엽 항공 프로펠러의 피치각 및 엔진 회전속도 변화에 따른 비행 조건 기반 성능 특성 연구 = Experimental Investigation of Performance Characteristics of a Three-Blade Aircraft Propeller with Varying Pitch Angle and Rotational Speed under Flight Conditions

다국어 초록 (Multilingual Abstract)

Aircraft Noise is a sound that humans do not want. In this study, based on the Rotax 914 engine used in Korea, the Propeller blade angle was changed by 1 degree for the 3-leaf “K company” Propeller and the 3-leaf “G” wooden Propeller, and the engine RPM was changed to examine the Noise and thrust changes. The purpose of this study is to check whether Noise and thrust loss are the least at the engine's maximum RPM, and to propose an aircraft operation plan in the noisy aerodrome area based on the values. This research further seeks to identify optimal propeller configurations that balance acoustic performance and thrust efficiency. The results are expected to aid in formulating guidelines for quieter flight operations near populated areas.
