Experimental 3-Blade Propeller

thingiverse

Experimental 3-bladed prop with the concept of noise reduction achieved through notching the trailing edge. This innovative approach draws from a recent noise-reduction technique used on jet airliner ducting, where notches are strategically placed to blend air flowing from high and low pressure areas. The same principle may be effectively applied to propellers. A standard version is also included for comparison purposes or establishing a baseline in terms of performance metrics. --- Update --- Further research has been conducted, revealing that the foundation of this idea is not as novel as initially thought. https://www.google.com/patents/US4089618 Despite this discovery, exploring quieter propellers remains an intriguing area of investigation, particularly for R/C aircraft applications where reduced noise levels can be beneficial.
