I'm crowdfunding for my new universal propeller, sectional nozzle propeller aka beetle elytra propeller after being granted 20 years patent NG/P/2016/417 by the Nigeria Patent office via the following weblink.

A photo of a toy helicopter on which the propeller is mounted is attached to this thread and video of a 6.o cm by 3.0 cm sectional nozzle propeller can be viewed on the indiegogo webpage.
Just the discussion as to whether this propeller has universal application and could be a versatile tool in the art of propulsion.
