A Bioinspired Modification For Uas Propeller/Rotor Noise Reduction, Mark N. Callender
A Bioinspired Modification For Uas Propeller/Rotor Noise Reduction, Mark N. Callender
ASA Multidisciplinary Research Symposium
This projects presents a bioinspired modification to UAS propellers/rotors for noise reduction. Sound pressure levels (SPL) and thrust for modified propellers were compared to a baseline propeller. The bioinspired modification yielded lower SPL with a requisite increase in rpm in order to maintain a chosen level of thrust.
