PROPULSIVE DEVICE Russian patent published in 2000 - IPC

FIELD: transport engineering; ground, water or air vehicles. SUBSTANCE: propulsive device with variable geometry drive has drive shaft with-fitted-on hub with working member installed for rotation relative to drive shaft, and rigidly installed bushing. Hub is mounted for rotation between disk-shaped driving members mated with hub. Sectional bushing and disk-shaped driving members consist of inner and outer bushings movable relative to each other and driving and outer disks. Axes of disk rotation are arranged at angle relative to intersecting generatrices of outer and inner cylindrical surfaces of outer bushing parallel to axes of intersection and perpendicular to corresponding relatively intersecting outer and inner planes of driving disks. The latter are coupled with outer bushing by rotational engagement for axial displacement and by flexible members, with control axle. Working member is coupled with self-contained drive shaft by flexible members. EFFECT: simplified design of drive and control of propulsive device. 2 cl, 1 dwg
