20090065640 | BRAKING-ENERGY EQUALIZATION SYSTEM - A braking-energy equalization system applied to an aircraft undercarriage, which undercarriage includes at least two sets of landing gear, with each set of landing gear including at least two wheels and with each of wheels being equipped with a brake, wherein the system includes means intended to introduce a delay time to delay the braking of the brakes having a higher braking torque in comparison with the other brakes having a lower braking torque, so as to equalize the braking energies absorbed by the brakes of the landing gear during the landing or during an interrupted takeoff of the aircraft. | 03-12-2009 |
20100006699 | LANDING GEAR METHOD AND APPARATUS FOR BRAKING AND MANEUVERING - Aircraft landing gear comprised of a wheel hub motor/generator includes alternating rotors and stators mounted with respect to the wheel support and wheel. The invention in certain embodiments can provide motive force to the wheel when electrical power is applied, e.g. prior to touch-down, thus decreasing the difference in relative velocities of the tire radial velocity with that of the relative velocity of the runway and reducing the sliding friction wear of the tire. After touchdown the wheel hub motor/generator may be used as a generator thus applying a regenerative braking force and/or a motorized braking action to the wheel. The energy generated upon landing may be dissipated through a resistor and/or stored for later use in providing a source for motive power to the aircraft wheels for taxiing and ground maneuvers of the aircraft. Methods and apparatuses for nose gear steering and ABS braking using the disclosed invention are described. | 01-14-2010 |
20100078519 | METHOD TO DEGRADE BRAKING MODES - A system, apparatus and method of controlling a braking system of a vehicle having a plurality of rotating wheels and a plurality of brakes, each brake corresponding to one of the plurality of wheels, is provided.
