FIELD: transportation.
SUBSTANCE: invention relates to amphibious transport units on an air cushion. Amphibious transport unit for evacuation of injured in case of emergencies of regional scale, comprising a body, a cargo hold with transport rigging arrangement, a room to locate people evacuated in emergencies, which is made as a single room or several cabins of an amphibious aircraft, each being a metal stamp-welded frame. The frame comprises bearing shaped structures, inside which there are packages of sound-vibration-heat-insulation elements. The cabin frame is connected to bearing structures of the aircraft by means of a vibration insulation system, comprising an upper suspension, including two rubber vibration isolators of the upper suspension and two of the lower one. Vibration isolators of the lower suspension are made in the form of symmetrical beaded meshed vibration isolators, each comprising a base, elastic meshed elements. At the same time the base is located in the middle part of the vibration insulator and is made as a plate with fastening holes. Meshed elastic elements are rigidly connected to the base by means of support rings. Besides, in the upper meshed elastic element in the center there is a dry friction damper located axisymmetrically.
EFFECT: invention provides for lower level of noise and vibrations.
