Image Number 4 for United States Patent #6685137.
The invention provides an aircraft having a flight control system (20) comprising an aerodynamic lift generator, and a control system in use the lift provided by the lift generator. The lift control system in one embodiment uses a concentrated mass mounted within a longitudinal body of the aircraft, the concentrated mass comprising at least one existing aircraft function and/or system mounted on a support in a confined area. Bearings permit relative movement between the support for the concentrated mass and at least a portion of the lift generator. An actuator is provided for causing such relative movement whereby in use the center of aerodynamic lift and the center of gravity of the aircraft may be moved relative to one another for effecting flight control.
