Three-wing, six tilt-propulsion unit, VTOL aircraft
First Claim
1. A vertical takeoff and landing aircraft comprising:
- a fuselage;
three wings attached to the fuselage;
six synchronously rotatable, thrust producing propulsion units located at approximately equal angular positions about a yaw axis of the aircraft;
wherein one propulsion unit is mounted above, below, or on each half of the three wings, and each propulsion unit is independent from the other propulsion units, and wherein each rotatable propulsion unit comprises a propeller and a propeller hub, and wherein each propeller comprises;
a plurality of blades, wherein each of the plurality of blades comprises a hole along a longitudinal axis of each blade; and
a plurality of rotatable rods, wherein each of the plurality of rods extends into the hole of a corresponding one of the plurality of blades, wherein a proximal end of each of the plurality of blades is enclosed in or adjacent to the propeller hub and rotatable around the corresponding one of the plurality of rotatable rods, and wherein a distal end of each of the plurality of rods is fixed to a distal end of the corresponding one of the plurality of blades.

Abstract
A vertical takeoff and landing aircraft having a fuselage with, preferably, three wings and six synchronously tilt-able propulsion units, each one mounted above, below, or on each half of the aforementioned three wings. The propulsion units are oriented vertically for vertical flight and horizontally for forward flight. Each propulsion unit comprises a propeller having a plurality of blades, where the pitch angle associated with the distal end of each blade and the proximal end of each blade are independently adjustable. As such, each of the propellers can be adjusted to exhibit a first blade pitch angle distribution optimized for vertical flight and a second blade pitch angle distribution optimized for forward flight.
