Abstract

Pemahaman tentang aerodinamika merupakan dasar teoritis yang krusial dalam studi penerbangan. Siswa perlu memahami prinsip-prinsip dasar seperti gaya angkat, hambatan, dan daya dorong yang berkaitan erat dengan aerodinamika untuk memahami bagaimana pesawat terbang dapat mengudara dan bergerak. Pemahaman aerodinamika juga sangat penting dalam proses desain dan konstruksi pesawat terbang. Mengingat pentingnya pemahaman tentang aerodinamika dalam konteks pendidikan penerbangan, pengabdian ini bertujuan untuk memberikan akses, pelatihan, dan pemahaman yang lebih baik kepada siswa SMK Penerbangan tentang prinsip-prinsip dasar aerodinamika. Hal ini diharapkan akan memberikan kontribusi yang signifikan dalam persiapan siswa untuk menghadapi tuntutan dunia industri penerbangan yang terus berkembang. Pengabdian dilaksanakan di SMK Penerbangan AAG Adisutjipto pada Selasa, 11 Juni 2024 dengan peserta 20 siswa. Hasil test menunjukkan peningkatan pemahaman peserta terhadap aerodinamika. Di sisi lain, hasil evaluasi menunjukkan kepuasan peserta terhadap kegiatan ini.

Abstract

The increasing use of drones in Indonesia potentially causes noise pollution due to propeller-generated sound. One widely studied approach to reducing propeller noise is trailing edge modification. Noda et al. (2019) showed that serrated gurney flaps can reduce noise at low RPM with minimal impact on thrust, although their effectiveness decreases at higher RPM. One factor that has not been considered is the serration’s installation angle. This study investigates the effect of adding an inclined serration flat-plate on the noise and thrust of a propeller. Numerical simulations were conducted using the frozen rotor method with the k-ω SST turbulence model and the Ffwocs-William and Hawking acoustic analogy. The results show that the serration increased thrust up to 41.707% at 10,000 RPM. In contrast, the trend of Sound Pressure Level (SPL) towards frequency generally increased, leading to a rise in Overall SPL (OASPL) up to 3.497 dB at 10,000 RPM
