RESCUE HOVERCRAFT CABIN Russian patent published in 2018 - IPC B60V1/18 F16F3/08 

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding. Rescue hovercraft cabin is mounted on the superstructure platform. Low noise cabin is made with a suspended acoustical ceiling for the passengers and maintenance personnel. Vibration isolator in the passenger version is made in the form of a washer mesh vibration isolator and contains a base, an elastic mesh element and washers interacting with the bushings. Base is composed by the plate with mounting holes. By the lower part mesh elastic element rests on the base and is fixed by the lower washer, rigidly connected to the base. Upper part is fixed by the upper pressure washer, rigidly connected to the centrally located ring. Density of the mesh structure of the elastic mesh element is in the optimal range of values: 1.2÷2.0 g/cm³. Density of resilient mesh element external layers mesh structure is by 1.5 times exceeds density of the elastic mesh element inner layers mesh structure. Resilient mesh element is made combined from mesh frame filled with polyurethane.

EFFECT: noise reduction is achieved.
