Description
  • 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 measures influence 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 used as 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.
