tailieunhanh - Experimental study on static thrust characteristics of Master Airscrew E9x6 propeller with duct

The results obtained will be compared with the manufacturer's results (conducted by the University of Illinois, without duct, in static condition), and compared to the numerical simulation results. From there, choose the kind of propeller that match the design of the UAV. | 60 Science and Technology Development Journal, vol 20, 2017 Experimental study on static thrust characteristics of Master Airscrew E9x6 propeller with duct Nguyen Ho Nghia and Ngo Khanh Hieu Abstract— Previous studies at HCMUT have been carried out on free propellers in static condition for Unmanned Aerial Vehicle (UAV), not much data exists for ducted propellers. According to theory, the ducted propeller has some better characteristics than than the free propeller. The paper presents an experimental design, based on load-cell deformation, for the small ducted propeller. The experimental model will be carried out for the Master Airscrew E9x6 propeller in the case with duct and without duct, in the static condition. The results obtained will be compared with the manufacturer's results (conducted by the University of Illinois, without duct, in static condition), and compared to the numerical simulation results. From there, choose the kind of propeller that match the design of the UAV. Index Terms— thrust measurement system, ducted propeller, Master Airscrew E9 6 propeller 1 INTRODUCTION P ropeller performance at low Reynolds numbers has become increasingly important in the design and performance prediction of unmanned air vehicles (UAVs). While propeller performance for full-scale airplanes has been well documented since the pioneering days of aviation, data on propellers at low Reynolds numbers has been scarce.
