The objective of the present study is the new design of a 6-blade propeller for the LFU 205 aircraft of the German Aerospace Research Establishment (DLR). A preceding experimental study has indicated the potential of noise abatement by reducing the blade tip Mach number while maintaining a constant engine speed. Starting from the results of the experimental study and fundamental considerations with regard to noise reduction and aerodynamic quality, a new propeller is designed on the basis of a diameter reduction from 1.93 m to 1.5 m. Besides the design of a 6-blade and a 4-blade propeller, a propeller, measured in the German-Dutch Wind Tunnel (DNW) with a diameter of 2.03, is used both as a reference propeller and to verify the methods applied here.
