METHOD FOR AMPHIBIOUS VEHICLE CASUALTY CONTROL IN CONDITIONS OF LOW TEMPERATURES Russian patent published in 2015 - IPC B60F3/00 F41H7/00 

FIELD: transport.

SUBSTANCE: invention relates to methods for casualty control of amphibious vehicles. The method includes installation of shrouds from outside of vehicle which shrouds are connected with vehicle's body with possibility to form cavities opened form beneath with possibility to control feeding power plant exhaust gases into them. In case of amphibious vehicle straight movement and absence of rocking, exhaust gases feeding into shroud cavities is performed in a smooth manner. In case of straight movement and rocking, vehicle tilting amplitude is measured, and proportionally to its value exhaust gases supply to cavities from tilt side and opposite side respectively is increased or reduced. In case of turning the exhaust gases supply to cavities from turning side is ceased and from opposite side is increased proportionally to vehicle velocity squared and inversely proportional to the radius of its turning. On the outer surfaces of shrouds, placement of watertight reservoirs of variable volume, for instance bellows, is provided with possibility to increase their volume depending on need to improve buoyancy and stability both in case of constant motion and during turning.

EFFECT: improved buoyancy and safety of amphibious vehicle.
