Abstract
Results of aero-acoustic wind tunnel measurements on ultra-light aircraft propellers (2, 3, 4 and 6 blades) are presented numerically and graphically. They include thrust, torque and noise measurements in the helical Mach number range of 0.4 smaller/equal MH smaller/equal 0.7 and propeller pitch angles of 10 degree smaller/equal beta smaller/equal 25 degrees.
