FIELD: screw-propelled vehicles.
SUBSTANCE: invention relates to rescue vehicles equipped with a screw propeller. 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 through a transmission. The augers are installed in the bottom part of the body, along the sides of which, in the lower part, retractable ballonets are located in closed niches. On the upper part of the body, additional autonomous and remotely controlled augers are mounted on a rotating telescopic rod. The ballonets, located in the side niches in the working position, have a cone-shaped shape, the top of which is directed towards the stern, and the base at the bow smoothly transforms into a cylindrical ski-shaped shape.
EFFECT: increase in operational reliability is achieved when the auger exits the water onto the ice surface.
