AIRCRAFT DRIVE, UNDERCARRIAGE ASSEMBLY, AIRCRAFT, SET OF DRIVE UNITS, AND METHOD OF PART DISPLACEMENT Russian patent published in 2012 - IPC B64C13/34 

FIELD: transport.

SUBSTANCE: invention relates to aircraft airframe units drives. Drive 2 comprises housing 4, primary engine 6 to create rotary motion, first reduction gear 10 mounted to convert rotary motion of primary engine 6 in rotary motion of output shaft with higher torque and low rpm. First reduction gear comprises casing 14 secured to rotate relative to drive housing 4 and second reduction gear 16 arranged to convert rotary motion of housing 14 of first reduction gear 10 in that with lower torque and higher rpm. Brake 20 is mounted to influence rotary motion from second reduction gear 16. With first reduction gear 10 unlocked in operation, applied brake inhibits displacement of first reduction gear case relative to housing 4 of drive 2. With first reduction gear 10 locked, brake 20 gets released to allow first reduction gear case 14 to revolve relative to drive housing 4. First reduction gear may revolve at output in the range of plus 180° to minus 180°. Besides, second engine may be used to drive second reduction gear. Proposed drive consists of the set of assembly units and parts and may be used for control over aircraft landing gear leg.

EFFECT: part may be moved with drive reduction gear locked.
