FLYING VEHICLE Russian patent published in 2004 - IPC

FIELD: aeronautical engineering; heavier-than-air vertical takeoff and landing flying vehicles. SUBSTANCE: proposed flying vehicle has cabin with supporting landing gear, engine, blades interacting with air medium and control unit. Novelty of invention consists in availability of differential gear with half-shafts located symmetrically on sides of cabin; each blade is asymmetrically secured on axle on which bevel gear is fitted. Mounted freely on each half-shaft is transfer member made in form of bush with bevel gears at its ends; said bevel gears are thrown into engagement with bevel gear fitted on axle of blade. Each half-shaft is provided with bushes where blade axles are mounted symmetrically in two rows over sides of cabin; each axle is located radially relative to half-shaft. Blade control unit located on each half-shaft includes gear fitted coaxially on half-shaft and thrown into engagement with gear intended for change of direction of thrust vector; device is also provided with twin intermediate gear freely mounted on pin of first gear, revolution regulator made in form of brake for each half- shaft, synchronizing member made in form of bush freely fitted on half- shaft and provided with gear at one end; said gear is used for engagement with bevel gear fitted on axle of each blades of row close to cabin; its other end is provided with gear used for engagement with second gear of twin intermediate gear; device is also provided with drive gear rigidly secured on half-shaft for engagement with first gar of twin intermediate gear so that ratio between drive gear and bevel gear fitted on blade axle is equal to 1:1. EFFECT: reduction of interaction of control forces and torques; facilitated control of flying vehicle. 3 dwg
