By mounting a lift engine and a lift/cruise engine closely to the center of gravity of an aircraft and by orienting the respective engines such that the thrust axes thereof are arranged for ensuring that the vector sum of the lift engine thrust and the lift/cruise engine thrust pass through the center of gravity at all times, a fuel efficient aircraft can controllably takeoff and land vertically. To provide for vectoring the thrust of the respective engines, different nozzles are provided. Further, to provide for pitch, roll and yaw control, a vane assem...
An aircraft having a fuselage, comprising: a first engine mounted coaxially along an axis transversely oblique to the longitudinal axis of the fuselage for producing a first thrust along a first thrust axis; a second engine mounted in front of the first engine in a parallel relationship to the longitudinal axis for producing a second thrust along a second thrust axis; a swivel nozzle engaged to the output of the first engine for vectoring the first thrust about at least two axes with respect to the first thrust axis against gravitational forces of the ea...
