MagBlade Safety Propeller awarded U.S. Patent
U.S. Patent 9,909,600 was issued to Russel Iwan Hawkins, one of the individuals in South Africa we spoke to a few years ago, on 6 March 2018 by the U.S. Patent Office.
The design involves blade edge covering members that are releasably securable to at least part of the edges of the propeller.
We first covered the propeller in an August 2012 post.
The propeller design is said to have been improved since then and their website has a “Get in Touch” link through which you can contact them for further information.
The patent stresses the safety characteristics of the propeller.
