MEANS FOR RESCUE DURING OPERATION IN ICE CONDITIONS Russian patent published in 2023 - IPC B62D57/00 B60F3/00 B63C9/00 

FIELD: vehicles.

SUBSTANCE: all-terrain vehicles equipped with auger propellers and intended for movement across ice-covered water bodies. A safe and traveling screw-propelled vehicle, operated in ice-covered waters, contains a body in which rooms for passengers and transported cargo are located, as well as a power unit that drives the running augers installed in the bottom part of the body through a transmission. In the lower part of the sides there are niches that can be closed with flaps, in which sectional airbags are located, isolated from each other. The first bow airbags are shifted aft by an amount equal to the pitch of the auger in the bow, and the running augers in the aft have a cone shape, ending with propellers, the blades of which are connected by rings, the outer diameter of which is less than the outer diameter of the auger ribs by two heights of these ribs.

EFFECT: reliability is achieved when the auger moves out of the water onto the ice surface, as well as increases the efficiency of the auger propellers.
