History

Using GOA “Paisys VII” and “Paisys XI”, between 1977 and 1991, the Institute of Oceanology of the USSR Academy of Sciences conducted 16 expeditions to the Atlantic , Pacific, and Indian oceans .

Design

Corps

 
Pisces v

All devices had four strong spheres made of high-strength alloy steel. The largest nasal sphere is habitable. It is a robust housing with three portholes, an access hatch and wiring passages. To prevent corrosion, on the outside it is covered with a thin layer of fiberglass on epoxy resin, and from the inside, thermal insulation made of polystyrene and fiberglass.

The feed sphere is a strong leveling tank divided by a horizontal coating into two parts: the lower - the tank and the upper, where the equipment of the on-board systems was located. Different small nasal spheres served as differential tanks. All durable spheres were mounted on a supporting steel tubular frame filled with oil. It also housed all outboard components. A lifting eye was attached to the frame from above, the lower part rested on two steel skis designed to place the GOA on the carrier deck or land it on the ground. Steel bolts attached to the frame sections of the casing of spherical plastic lined with fiberglass.

Powerplant

The electric power installation includes two rechargeable batteries located in the inter-side space in two oil-filled fiberglass sealed containers. The power supply of the driving motors, ballast pump electric motors, the differential pump and the hydraulic power unit, several outdoor lamps with a total power of 2.5 kW and the hydraulic control electromagnetic valves comes from a 120 volt battery. 24 V and 12 V batteries provide power to navigation, scientific and communications equipment. GOA is equipped with two propellers in the nozzles. They can rotate around a horizontal axis within 120 degrees. Movers can be used as marching and vertical. The DC propeller motor and gearbox of each screw are located in a capsule filled with oil and have individual pressure compensation, which is a continuation of the screw hub. The thrusters were equipped with an emergency hydraulic device for cutting the supply cable and recoil propulsors. For piloting the Paisys GOA , engines working together moving the underwater vehicle in any direction and a ballast system for moving vertically worked together.

Other facts

In 1973, the small Canadian firm Heiko was commissioned to design a Paisys IV deep-sea research project. The device was designed and built, but, in connection with the "cool" relations between the USSR and the USA, it was purchased by the Canadian government.
In the mid-1970s of the last century, an agreement existed between the United States and European countries on the ban on the supply of new technologies to the USSR and the socialist countries. But there was no ban on the purchase and export of products and components. This is exactly what the Soviet company took advantage of by renting a room in Zurich for the assembly of two Paisys devices. One durable housing unit was ordered in Japan , the other in Canada. The first apparatus was assembled in Zurich , transported by trailer to Genoa , tested in the Mediterranean Sea . Then they loaded him onto the ship “Fryazino”, going to Novorossiysk . So the Institute of Oceanology of the USSR Academy of Sciences received Paisys-VII.
Paisys-XI was assembled in Vancouver , tested in the Pacific Ocean and transported to Vladivostok on a foreign vessel, from where Paisys-XI was transported to Novorossiysk on the IL-76 .
So in the CCCP, ten years before the appearance of the “Worlds” , in 1975 - 1976 two research inhabited vehicles appeared, capable of diving two thousand meters.
