Three wing, six-tilt propulsion unit, VTOL aircraft
First Claim
1. A vertical takeoff and landing aircraft comprising:
- a fuselage;
three wings fixed to the fuselage, including a front wing, a middle wing and a rear wing; and
six rotatable propulsion units,wherein first and second propulsion units are fixed to the front wing, third and fourth propulsion units are fixed to the middle wing and fifth and sixth propulsion units are fixed to the rear wing, andwherein each of the six propulsion units is located radially from each of two adjacent propulsion units by equal or substantially equal angles.

Abstract
A vertical takeoff and landing aircraft having at least three wings and at least six propulsion units, each of which are located radially from two adjacent propulsion units, by equal or substantially equal angles. The at least six propulsion units together being located symmetrically, or at substantially symmetric positions, about the approximate center of gravity of the aircraft, when viewed from above. A vertical stabilizer may or may not be employed. If no vertical stabilizer is employed, yaw control during horizontal flight may be achieved through differential thrust using the at least six propulsion units. Yaw control during vertical flight may be provided by a plurality of yaw control panels. Absent yaw control panels, yaw control during vertical flight may be provided using differential propulsion unit tilt angles.
