Title:
TIP-PATH AIRFOIL THRUST PRODUCTION IN ROTARY-WING AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2019/018832
Kind Code:
A3
Abstract:
The rotational velocity of the rotary-wing blade 1 is lowest closer to the hub 5 and increases outward towards the tip-path 15 of the rotor blade 1 during rotation. Moving thrust to the tip-path 1 of a rotary-wing 2, 3, and 4, provides an aircraft that is more efficient than prior art of central axis driven systems: engines, electric motors, jets, or turbines that forced rotation 11 through a central axis mast 5, and 6, which transferred torque 11 through a hub 5 connected to the body of the aircraft to the center axis 16 of the rotary-wing 1 rotating in the plane of rotational direction. In milliseconds, piezoelectric wafers mounted onto propeller airfoil blades 2, 3, and 4 morph from a symmetrical airfoil into a nonsymmetrical airfoil (chambered or any shape), to increase air density for more lift during high speed propeller rotation.
