TRANSPARENT HULL OF MANNED UNDERWATER VEHICLE Russian patent published in 2023 - IPC B63G8/00 B63B3/13 

FIELD: underwater shipbuilding.

SUBSTANCE: invention is related to design of strong hydrostatically resistant hulls of habitable underwater vehicles. The transparent body of the manned underwater vehicle includes a transparent sphere with an upper access hatch and a cable and pipeline entry device, including a cable and pipeline entry plate. The entrance hatch includes a coaming, means for its installation and an entrance hatch cover hinged on the coaming bracket with a battening mechanism with a central shaft and a pressure equalization valve, with a telescopic spring-type balancing device with a steel compression spring. The transparent solid sphere is made with an outer diameter of up to 2200 mm and a uniform wall thickness of up to 290 mm, and is equipped with at least one lateral cable and pipeline entry device, each cable and pipeline entry plate of which is installed at an angle of its central axis relative to the vertical plane of the strong body not more than 40° and at an angle of its central axis down relative to the central horizontal plane of the strong body not more than 30°. Entrance hatch cover body and each body of cable and pipeline entry plate are made in form of an outer truncated cone with a height equal to the thickness of the strong body, and a central spherical segment with a thickness of not more than 40 mm and 50 mm, respectively. The pressure equalization valve is built into the central shaft of the inlet hatch cover battening mechanism and is a double-sided hollow longitudinal shaft with through end holes and means for opening and closing them. At the same time, the coaming, the body of the inlet hatch cover, the mechanism for closing the cover, the pressure equalization valve, the elements of the balancing device, the body of the cable and pipeline entry plate, and the fastening elements are made of titanium alloy.

EFFECT: expansion of the arsenal of transparent hydrostatic pressure-resistant durable hulls for manned underwater vehicles with increasing immersion depth is achieved.
