Abstract

Unmanned flight has been a part of everyday life. According to BI Intelegent from 2015 to 2020, the annual growth rate of small commercial UAVs is expected to reach 19%, which will result in 22 million UAV shipments by 2022. In addition, the global UAV market will reach around 10 billion USD by 2023. Problem that comes up with UAV is the propeller which based on its characteristic is a source of noise. Main noise-induced disturbance are increasing discomfort or stress, irritation, confusion, elevated blood pressure, headaches and the worst case is hearing loss. To reduce noise level caused by propeller some special treatment needed to be done to its design. The serrated trailing edge theory was first introduced by M.S. Howe and then developed by applying the serrated trailing edge to the propeller by Zhe Ning, Richard Wlezien, Hui Hu. The journal concluded that the serrated trailing edge can reduce noise up to 1.6dB. In this study, the author makes a propeller design with a serrated trailing edge using the Solidwork application. After making the design, proceed to the process of making the propeller, after being made it enters the testing stage using the Sunnysky X-2820 motor testing tool on 3000, 4000, 5000 RPM and noise is measured with a sound level meter with several differences in distance, namely 1m, 1.5m, 3m to determine the noise and thrust generated by each propeller.

Abstract

The propeller blade is a component that is the main source of thrust on the ATR 72 aircraft. Based on data from the Aircraft Flight Maintenance Log (AFML) for the period 2019 – 2021 ATR 72 aircraft, the propeller blade component was damaged causing the need for unscheduled removal which had impact losses to airlines such as delays and aircraft-on-ground (AOG). This study aims to find the root causes of damage to the propeller blade components. Analysis was carried out using the Root-Cause Failure Analysis (RCFA) method using fault tree analysis (FTA) and fishbone diagrams as tools so that factors related to propeller blade damage will be found. The results of analysis using fault tree analysis (FTA) and fishbone found that the root cause of damage to the propeller blade was in the area of ​​the heating element (de-icer) as the top event, while the propeller blade operation, propeller blade maintenance and the ATR 72 aircraft operating environment were the intermediate events
