Abstract
A propulsion engine for an aircraft comprises an enclosure having a longitudinal axis oriented in a direction of travel of an aircraft, the enclosure including a series of walls and a plurality of ducts arranged along the longitudinal axis. Each of the ducts including a number of walls that are either dynamic or static in movement. Each of the ducts includes a central axis that is angled at, or can be adjusted to, an angle toward the front wall of the enclosure such that a top end of each duct is toward the front wall of the enclosure. A fan is disposed in each of the ducts configured to generate airflow along the respective central axes from the top end to the bottom end to provide lift and thrust to the aircraft.
