FIELD: sport; mass entertainment.
SUBSTANCE: invention relates to design of individual small-scale devices used for rescue of people in case of emergencies, and also can be used in sports and leisure activities, training young people to technical methods of sports on water. Rescue device comprises a floating U-shaped body, the bottom of which in cross section is made in the form of an inverted semi-circle. Two injection devices in the form of impellers equal to low power in the compressor mode are used at the ends of its tail part as propellers and hydrodynamic jets coming out of nozzles of impellers are created. Braking of device is carried out by fixing valves with possibility of their closing by means of remote control panel located inside nozzles. Nozzles of impellers are connected to each other by air tube passing in middle part through housing in form of closed ring with valve, also controlled panel, wherein the air tube passes through the nodes made by the tubular arcs through the attachment points to the housing on the outer side. Besides, the valves have separate axes with the possibility of rotation and their adherence to the nozzle walls, with the possibility of the flow force separation and the gas jet driven for the gas flow turning. Device is additionally equipped with an air cushion of safety located inside along external contour between ends of tail part of the housing. Device is made in the form of independent buoyancy of body as a whole and is controlled by means of remote control panel from shore or from ship side. Outside the housing is equipped with light and sound signals, creating additional assistance in human rescue. Front part of the bottom of the streamlined body is protected by a layer of material made with freely protruding one end separate elastic rods made of elastic polyethylene materials in the form of a brush rigidly connected to the protective coating of the material.
EFFECT: possibility of stable and controlled movement at speed over water, shallow water and ashore on compressed air flow, as well as increase of safety degree of person suffering distress on water.
