FIELD: vessels and other watercrafts.
SUBSTANCE: invention relates to marine equipment, in particular to underwater vehicles, and is intended to provide their movement at specified distance from sea bottom. Disclosed is a device for bottom movement of an underwater vehicle, comprising a meshed wing with underwater vehicle grating wing with deepening planes, rigidly connected with buoyancy and rigid crutch, having a touch element with sea bottom, at that, the setting angles of attack of the deepening plans to the longitudinal axis of the meshed wing are not less than 90 degrees, the ratio of the height of the meshed wing to its span is from 0.25 to 4, and the distance between parallel plans is from 0.4 to 1.25 of their chords.
EFFECT: technical result of proposed device is retention of underwater vehicle in narrow range of distances from sea bottom with reduction of weight and dimensions of device.
