Abstract
Tujuan dari penelitian ini adalah untuk mengetahui pengaruh
profil daun propeller dan interval rotor-tip terhadap aerodinamis
termasuk efisiensi rotor pada kondisi melayang. Terdapat tiga
tipe propeller yang digunakan. Semuanya dengan interval rotortip
yang sama TI = 0.5R. Hanya untuk kasus propeller tipe 3 saja
dimana TI divariasikan (TI = 1.0R, 0.5R, dan 0.03R). Batasan
masalah pada studi ini adalah menganulir efek dinding –
mengingat eksperimen dilakukan pada tempat yang luas. Gaya
angkat, kecepatan rotor, serta konsumsi daya adalah variablevariable
yang diukur untuk memperoleh data. Gaya angkat diukur
menggunakan force gauge, kecepatan rotor diukur menggunakan
tachometer, sedangkan konsumsi daya diperoleh melalui signal
dari power supply. Pitch angle yang lebih kecil serta kecepatan
rotor yang tinggi berkontribusi pada efisiensi aerodinamis
terbaik. TI/R yang lebih lebar juga berkontribusi pada efisiensi
rotor yang lebih baik.

The purpose of this research is to experimentally research how
the propeller blade profile and different rotor-tip interval have
effect to rotor efficiency at the hovering state. In this study, the
effects of propeller blade geometry on aerodynamic
characteristics included rotor efficiency of hovering quad-rotor
are investigated experimentally. Three kinds of propellers are
used and examined. All in the same distance of rotor-tip interval
(TI) 0.5R. Only for the case of Type 3 propeller the TI is varied
(TI = 1.0R, 0.5R, and 0.03R). The limit condition of this study is
the negligible effect of the side wall – this is due to the
experiments are performed in a large space. Lift, rotating speed
of rotor and consumed power are measured in order to acquire
data. The lift is measured by a force gauge, rotating speed of
rotor is measured by a tachometer, while consumed electric
power is obtained from the signal to the power of power supply. It
is found that the smaller pitch angle and higher speed rotation
contributes to the best aerodynamic efficiency. In addition, wider
TI/R corresponds to better rotor efficiency also.
