Abstract: Systems and methods for mechanically rotating an aircraft about its center-of-gravity (CG) are disclosed. The system can enable the rear, or main, landing gear to squat, while the nose landing gear raises to generate a positive pitch angle for the aircraft for takeoff or landing. The system can also enable the nose gear and main gear to return to a relatively level fuselage attitude for ground operations. The system can include one or more hydraulically linked hydraulic cylinders to control the overall height of the nose gear and the main gear. Because the hydraulic cylinders are linked, a change on the length of the nose cylinder generates a proportional, and opposite, change in the length of the main cylinder, and vice-versa. A method and control system for monitoring and controlling the relative positions of the nose gear and main gear is also disclosed.

Abstract: A tire spinning assembly for includes a tire that may be coupled to landing gear of an aircraft. A plurality of vanes is coupled to the tire. The vanes are frictionally engaged by air when the landing gear are deployed thereby rotating the tire. The vanes are oriented such that the tire is rotated in a direction and a speed corresponding to a direction and a speed traveled by the aircraft. The rotation of the tire reduces an amount of friction between the outer wall and ground when the aircraft lands.

Abstract: A driving device for driving a wheel of an airplane in a direction same as that of a revolution of the wheel after landing, includes a revolution drive disc having a flat ring plate having an attachment portion adapted to attach on a side surface of a tire of the wheel; and a plurality of fins arranged on the ring plate. The plurality of fins is obliquely arranged on an outer side surface of the ring plate so that when the plurality of fins receives relative atmospheric air flow, a torque generated by the fins at a lower side of the tire in the direction same as that of the revolution of the wheel after landing is larger than a torque generated by the fins at an upper side of the tire in a direction reverse to that of the revolution of the wheel after landing.

Abstract: In the proposed method, each landing gear wheel is rotated with the aid of one of the radial- or axial-type air turbines which are mounted on said wheel, rotate in opposite directions and to which compressed air from the main engines or from an auxiliary power-generating plant of the aircraft is fed. The wheels are spun by one of the turbines before landing or during forwards movement on the ground, while the other turbine is used for braking after touchdown, and also for reversing and for turns when manoeuvring. Air is also used for bleeding and cooling a wheel brake. Non-communicating air collectors of the turbines are connected by a telescopic pipe, which is fastened on a landing gear leg, via control valves to on-board compressed-air sources. Brake stator discs have through-channel sectors and are nozzle diaphragms, while rotor discs have through-channels arranged uniformly around the circumference and are working wheels of the axial turbine. Nozzle apparatuses of the radial turbine are mounted on the stator, while the working wheel is mounted on the internal rim of the landing gear wheel. The nozzle apparatuses are connected by sector air ducts to the corresponding air collectors.
