Claim 5:
6. A multi-motor propulsion engine for an aircraft, comprising:
a. an enclosure having a longitudinal axis oriented in a direction of travel of the aircraft, the enclosure including an aerodynamic nose, a rear enclosure section having a reduced rear body section, a left side wall, and a right side wall;
b. a plurality of ducts arranged along the longitudinal axis of the enclosure, wherein each of the ducts is aligned in the enclosure with a central axis at a forward angle relative to the longitudinal axis of the enclosure;
c. a plurality of fans with each fan fixed in one of the plurality of ducts, wherein the plurality of fans are configured to generate airflow along the respective central axis of each duct from a top end of the duct to a bottom end of each duct to provide lift and thrust to the aircraft;
d. wherein the reduced rear body section has a rear duct rear wall and a rear duct front wall and the rear duct rear wall is shorter than the rear duct front wall and a rear duct rear wall bottom portion of the rear duct rear wall is located vertically higher than a rear duct front wall bottom portion of the rear duct front wall;
e. wherein the front duct has a front duct front wall and a front duct rear wall wherein the front duct front wall is shorter than the front duct rear wall and a front duct front wall top portion of the front duct front wall is located vertically lower than a front duct rear wall top portion of the front duct rear wall; and
f. wherein the aerodynamic nose is fixed to the front duct front wall.
