Aerodynamic Design of the Propeller for Low-Speed Indoor UAV
Popis výsledku v původním jazyce
Aerodynamics design of propellers for slow-flying long-endurance indoor unmanned aerial vehicles (UAVs) is very challenging due to the problems caused by low Reynolds number. This causes high viscous losses and has also negative influence on the flow stability (i.e. flow separation). This leads to the relatively low efficiency compared with the propellers for the manned aircraft. Aerodynamic design is based on the method developed by Larrabee. The influence of propeller RPM and diameter on the efficiency is described and analyzed. The recommendation for the choosing of the appropriate values of both parameters is given for the case of the long-endurance indoor UAV with required flight endurance of several hours. The results can be generalized for the other classes of the propellers.
