VIBROPROPELLER WITH CONVERSION OF ROTATIONAL MOTION INTO PROGRESSIVE MOTION Russian patent published in 2010 - IPC B62D57/00 F03G3/00 

FIELD: transport.

SUBSTANCE: vibropropeller includes inertia-pulse converter with inertial rotating masses and mechanism for varying radius of their rotation, and pushers with their swinging movement mechanism. Mechanism for varying radius of inertial masses rotation consists of pair (or larger even number equal to number of rotating inertial masses) levers. On of the ends of each lever one inertial mass is rigidly fixed and on the other end - arc or roller pusher. The levers are pivotally connected with shaft with possibility of lever angular motion relative to axis perpendicular to shaft rotation axis. The shaft is mounted on bearing assembly which is installed on platform and connected with drive motor. Mechanism of pushers swinging movement is made as swashplate with power closing and includes swashplate and pushers making complex motion. Swashplate is rigidly connected with the platform and located concentrically relative to shaft axis in the plane parallel to inertial masses rotation plane. Profile of swashplate determines motion trajectory of lever mass centres.

EFFECT: lowering dynamic loads on vibropropeller and improvement of vehicle driveability due to reduction of deviations from motion trajectory.
