  • Publication number: 20180148162
    Abstract: An aircraft includes a fuselage having a tapered rear shape, a landing gear for moving the aircraft on a runway, a wing attached to the fuselage, at least a main engine for providing a main thrust and a rear fan, wherein the rear fan is attached to a tail section of the fuselage, wherein the aircraft is designed for conducting a take-off rotation around the landing gear during take-off from the runway, such that the tail section of the fuselage approaches the runway, wherein the rear fan is an open fan having fan blades extending in a radial direction to a longitudinal axis of the fuselage, wherein the fan blades are dimensioned to equal at least a boundary layer thickness of the flow along the fuselage and to be smaller than the gap between the runway and the tail section of the fuselage during the take-off rotation.

  • Patent number: 9884686
    Abstract: An aircraft including a fuselage extending along a longitudinal axis and having a rear end pointing reward of the aircraft, a main gear connected to the fuselage in a main gear position with respect to the longitudinal axis, and an engine for propelling the aircraft provided outside of the fuselage and attached to the fuselage via an attachment device between the main gear position and the rear end, wherein the engine generates a repulsive air stream streaming in the reverse direction. A surface element is moveably connected to the attachment device. The surface element moves between a neutral position at which it does not deflect the repulsive air stream, and a deflected position at which it deflects the repulsive air stream to assist aircraft rotation during take-off.
