Abstract: The present invention relates to a control system for an aircraft to compensate for crosswinds on landings. In one embodiment, the control system includes two mutually identical control surfaces having common end points, respectively; and an actuator to move completely the two mutually identical control surfaces, as needed to compensate for the crosswinds on landing.

Abstract: A steering method and system for large aircraft wherein during low speed taxi the main landing gear wheels are steered and the nose gear is free to castor. During high speed taxi such as during take off and landing, the main gear steering is locked out while the nose gear is steered.

Abstract: A six wheel, three axle, bogie type main landing gear for an airplane is retractable as a unit and is provided with a rearward set of wheels or a forward set of wheels that is steerable with respect to the non-rotatable bogie beam. The set of wheels turns in response to steering of the nose wheel past a given angle. A wheel assembly is mounted for rotation with respect to a vertical shaft supported by a fork extending longitudinally of the beam, and a pair of hydraulic cylinders turns the wheel axles with respect to the beam.

Abstract: The present system automatically stabilizes the travel direction of an aircraft rolling out after touchdown on a runway. A corrected difference control signal is supplied to the steering mechanisms of the aircraft, including, if desired, the brake system. The control signal is generated in a comparator or transducer which receives at its inputs an actually measured signal representing changes in the travel direction of an aircraft, and a rated signal to produce a combined steering signal which is supplied to the nose wheel steering and/or to the wheel brakes.

Abstract: A mooring and landing device for aircraft which are capable of vertical dent for landing comprising an inflatable tube-type device, or trunk, attached to the bottom surface of the craft. The trunk is in the shape of a doughnut and the open interior compartment formed by the inflated trunk and the bottom surface of the craft is evacuated to a pressure lower than atmospheric so that the difference between the compartment pressure and the atmospheric pressure moors the craft to the ground. The trunk is inflated to a pressure greater than atmospheric and may be formed with a plurality of holes to provide an air cushion for lubrication purposes.
