Hi everybody,
I have patented the Monica propeller :
The Monica propeller is a simple design for a high efficiency and low noise
propeller or rotor. This is achieved by
boundary layer aspiration and elimination of swirls of blade tip.
The Monica propeller uses the centrifugal force to create a "natural "
aspiration. One can illustrate the
phenomenon by thinking of the piece of flexible tube that one makes whirl.
The centrifugal force causes an air
flow, that may be highlighted by an audible whistle. The figure below
illustrates the application for the Monica
propeller : the skin of the propeller (may be the rotor of an helicoter) is
porous. Under this skin channels drain the
air towards the end of the blade. The aspiration is done naturally as soon
as the propeller is in rotation.
The flow of air at the tip of blade has anoyther benefit : it will blow
swirls of blade tip therefore reducing noise.
Blowing the swirls could also be done on fixed wings.
Any advice, suggestion, contact is welcome. Since this is only theoritical
what option would you go for :
1) look for research grant with a university ?
2) look for investors, venture capital ?
3) contact research institution ?
4) contact helicopter/propeller manufacturer ?
4) other ?
Thanks
