UNIT ON AIR CUSHION WITH GROUND PROPELLER Russian patent published in 2017 - IPC B60V1/11 B60V3/02 

FIELD: transportation; aviation.

SUBSTANCE: air cushioned unit with a ground propeller (ACU) comprises a body, a flexible barrier of an air cushion, equipped with an air duct, a propelling plant, comprising an engine, connected by means of a transmission with an air propeller with a supercharger, and a chassis comprising a ground propeller and made with change of the load extent. The chassis is equipped with acceleration sensors, the extent of unloading of the ground propeller and the traction. The supercharger is equipped with a device for measurement of its working parameters. Sensors of the ground propeller and the supercharger are connected to a conversion-amplification unit, which is connected to a comparison unit, joined via the unit by a signal amplifier, with the actuation device of variation of mutual position of the ground propeller and lower edges of the flexible barrier of the air cushion along the height of the body. The ground propeller is equipped with a pair of passive wheels, on which sensors of kinematic parameters of motion are installed. Ground propellers are equipped with sensors of rotation frequency, torque, vertical load. Sensors of kinematic parameters of passive wheels and sensors of the ground propeller are connected with a computer forming a signal to the ACU control panel.

EFFECT: reduced energy losses for ground chassis slipping.
