Citat:Helicopter seat
During the past decade, Russian designers have developed a rocket/parachute enforced escape system for combat helicopters. Designated K-37-800, the fully-automatic system is intended
for the Kamov Ka-so Black Shark attack helicopter (Hokum-A) and its two-seat version, the Ka-52 Alligator (Hokum-B). The pilot is extracted from the helicopter by means of a solid-propellant rocket motor attached to a strong, but light, cable, once the rotor blades have been jettisoned to facilitate unhindered egress. The pilot is also able to bail out of the helicopter manually.
The system consists of a seat, an on-board control module and the rocket-propelled towing device. The seat includes a life support system, a detachable seat back with a headrest, a suspension harness and operational systems which ensure safe escape from the helicopter. The seat pan houses a cushion containing the NAZ-/M survival kit (noseemy avareeny zapahs) and a dinghy, as well as the PS-3/A parachute system.
The seat pan's front wall houses the ejection control unit with actuating handles. On the right side of the seat pan (facing forward) is an override handle for disengaging the pilot's harness in the event of his deciding to abandon the helicopter manually without ejecting.
On production Ka-so helicopters now in service with Russian Army Aviation, the rocket/parachute escape system is used in combination with the ZSh-7V or ZSh-7VS special protective helmet, the KKO-VK-Ln oxygen system, and the KZO-Li 'Galoid' protective flying clothing.
So far, the K-37-8oo rescue system has not been used operationally, even though two examples of the Black Shark (including the first prototype) have been lost in crashes. On the second of these occasions, in Torzhok on July 17,1998, the upper and lower rotor blades of a production Ka-so collided during a high-g manoeuvre. The pilot, Major General Boris Vorob'yov, head of the Russian Army Aviation Combat and Conversion Training Centre, was killed. However, this was no fault of the rescue system - trying right up to the last moment to land the damaged helicopter, he did not attempt to use it.
