Influence of Noise Reduction on the Propeller Performance

Popis výsledku v původním jazyce

Noise reduction of propellers is considered as a very important issue in aviation. Principal means for the noise reduction are decrease in blade tip Mach number, i.e. lower propeller diameter and RPM, and increase in number of blades. All these measuresinfluence propeller performance and thus also efficiency. A novel method for the aerodynamic design of propeller is used for the investigation of these means for noise reduction on the propeller efficiency. A propeller for a small transport plane is usedas an example. ARA-D airfoils are utilized. Dependence of efficiency on propeller diameter, RPM and number of blades is discussed. Results provide important information for the design of the propeller with both low noise and high efficiency.
