METHOD FOR AIRCRAFT TOWING BY TRUCK WITH AUTOMATIC MULTIPLIER OF DRAW WEIGHT Russian patent published in 2008 - IPC B64F1/22 

FIELD: transportation.

SUBSTANCE: method of aircraft towing is performed by truck with automatic draw weight multiplier by means of tow bar-frame rigidly connected with aircraft NLG. Tow bar-frame is connected with truck frame through vertical guide, hydraulic lift cylinders and ball bearing. This method is implemented by means of control hydraulic cylinder pivotally connected with tow bar-frame using rod, and connected with each other by oil pipeline hydraulic lift cylinders and controlling manometer pressure source and pipelines. Ball bearing with longitudinal travel capability is mounted on truck. Controlling hydraulic cylinder is rigidly attached to truck frame in longitudinal vertical plane. Rod end of body is provided with hole connected with drain shut off by piston of controlling hydraulic cylinder and connected with blind side of hydraulic lift cylinders by means of controlled by it non-return valve. Tractive force for engagement of truck wheel drives is increased, wheel slip is reduced (particularly in autumn and winter when towing over wet and snowy surface).

EFFECT: possibility to tow heavy aircraft by more light trucks and reducing of fuel consumption are provided.
