1960-s PARACHUTE BACKPACK PSPK-1 FOR VOSTOK COSMONAUT LANDING SYSTEM, COA!

It's offered to your attention 1960-s parachute backpack for cosmonauts landing system PSPK-1. This system was used for all the first 6 Soviet cosmonauts who flew onboard Vostok - Gagarin, Titov, Nikolaev, Popovich, Bykovsky, Tereshkova. The abbriviation PSPK stands for Russian "parashutnaya sistema prizemleniya kosmonavta" what means "parachute system for cosmonaut landing". The backpack includes everything what Vostok cosmonauts had on their backs (see the photos below) except the parachute itself.

COA is included with the item.

Condition - used. The backpack is used. Technically its work has not been tested. Please see its additional detailed photos below.

PSPK-1 parachute backpack includes many unique and interesting mechanisms, "know-how" and materials to provide the safe landing of cosmonaut:

reliable and adjustable belts to hold cosmonaut's legs and shoulders with tightening mechanisms and quick unlocking mechanism;

packing places for parachute with steel hawser releasers passed through metallized holes;

barometric altimeters with timers for main and auxiliary parachute automatic actuators with pressurized gas cylinders;

the mechanism cocking parachute actuators when the ejection seat leaves the capsule;

"OSK" lock to release the free lines of main parachute if it does not open;

manual parachutes releasers;

lacing technology what is also used for space suits;

interesting suspension of carried emergency supply with quick release mechanism;

inflatable rubber collar in case of landing on water what can be inflated automatically with pressurized air container, or with cosmonaut's mouth;

electric wiring, connectors and sockets for communication and medical purposes;

reliable air hoses with connectors for pneumatic parachute actuators;

aluminium light and durable frame with corrugated part on the back to protect cosmonaut's spine from hard landing;

Historical reference

The Vostok spacecraft had no soft-landing system. After the main parachute had opened and the capsule was descending toward the ground, the cosmonaut had to use an ejection seat to rocket away from the capsule at the altitude of 7,000 meters and then land on earth under his own parachute system PSPK-1 (parashutnaya sistema prizemleniya kosmonavta). The seat separated from cosmonaut at the altitude of 4,000 meters, dropped down without parachute and wrecked. Cosmonaut landed with backpack and carried emergency supply called NAZ (nosimyi avarijnyi zapas) suspended with a rope below the cosmonaut. To test the system a mannequin, dubbed "Ivan Ivanovich" was flown and ejected on two test flights prior Vostok launch. These test flights cleared the way for Yuri Gagarin's first flight around the earth on 12 April 1961.
