Three wing, six tilt-propulsion units, VTOL aircraft
First Claim
1. A vertical takeoff and landing aircraft comprising:
- a fuselage;
a flapped or un-flapped front wing attached to the fuselage;
a flapped or un-flapped middle wing attached to the fuselage;
a vertical stabilizer and rudder attached to the fuselage;
a flapped or un-flapped rear wing attached to the fuselage or vertical stabilizer; and
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.

Abstract
A vertical takeoff and landing aircraft having a fuselage with 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 vertical for vertical flight, and horizontal for forward flight. The aircraft wings are placed such that the rear wing is above the middle wing which is placed above the front wing. The placement of each of the propulsion units relative to the center of gravity of the aircraft about the vertical axis inherently assures continued stability in vertical flight mode, following the loss of thrust from any one propulsion unit. The placement of the propulsion units, viewing the aircraft from the front, is such that each propulsion units'"'"' thrust wake does not materially disturb the propulsion unit to its rear. When engine driven propellers or rotors are utilized, flapped wing panels are attached outboard of the forward and/or rearward propulsion units to provide yaw control during vertical flight.
