Development of hydraulic transmission for implementing an active drive of the landing gear wheels of modern transport aircraft

Annotation An active drive of the wheels of the chassis is necessary on the take-off and run with reduced coupling characteristics of the airplane on an unpaved or icy runway in crosswind conditions to reduce lateral drift from the axis of the strip. The hydraulic transmission has been developed for the active drive of the wheels by aircraft chassis. At using a control system, that regulates the moment wheels characteristics and includes an adaptive circuit with neural network, it is possible to reduce the lateral drift of the aircraft about 30–40 %. The output parameters of the hydraulic motors intended for the landing gear wheels of aircraft weighting 21 tons are determined.
