SINOPSIS

The main points of an aeroacoustic design method for single and coaxial propellers with a given number of blades and with some of their dimensionless geometric characteristics are presented. The results of noise level minimization near the propeller are presented under a number of restrictions in the range of the control parameters, flight efficiency, propeller thrust at the start and at take-off, reverse thrust, and propeller mass.
