Abstract
1. Самоходное судно с выемкой на днище, предназначенной для образования единой воздушной каверны, начинающейся с редана в носовой части и ограниченной скегами по бортам и кормовым сводом в виде наклонной плоскости, причем полость выемки сообщена с источником воздуха повышенного давления, а внутри выемки размещены продольные кили для ограничения поперечного перемещения воздуха и поперек расположенные козырьки в виде наклонных пластин, следующих друг за другом вниз по потоку, отличающееся тем, что в задней части кормового свода симметрично диаметральной плоскости судна установлена обтекаемая наделка стреловидной формы в плане, предназначенная для защиты гребного винта судна от проникновения на него воздуха, выходящего из единой воздушной каверны.2. Самоходное судно с воздушной каверной на днище по п. 1, отличающееся тем, что наделка по высоте не выступает за пределы основной плоскости судна.1. Self-propelled vessel with a recess on the bottom, designed to form a single air cavity, starting with a step in the bow and limited by skegs along the sides and aft vault in the form of an inclined plane, and the cavity of the recess is communicated with a source of high pressure air, and longitudinal keels to restrict the lateral movement of air and transversely located visors in the form of inclined plates following one another downstream, characterized in that a streamlined swept-shaped cover is installed in the rear part of the stern vault symmetrically to the diametrical plane of the vessel, designed to protect the propeller of the vessel from the penetration of air from a single air cavity. 2. Self-propelled vessel with an air cavity on the bottom according to claim 1, characterized in that the attachment height does not protrude beyond the main plane of the vessel.
