NPP Zvezda K-36

The Zvezda K-36 is a series of ejection seats made by NPP Zvezda. Variants of this ejection seat have been used on a variety of aircraft, including the Su-25, Su-27, MiG-29, and the Sukhoi T-50.

Design
The K-36 Ejection seat provides rescue crew member in a wide range of speeds and altitudes of aircraft flight, from zero altitude, zero speed (zero-zero) upwards, and can be used in conjunction with protective equipment, such as pressure suits and anti-g garments. The seat consists of the ejection rocket firing mechanism, gear box, headrest, rescue system with a dome stowed in the headrest, operating systems, all of which are aimed at providing a safe bail-out. The ejection seat ensures safe emergency escape of a pilot within the range of velocities (Ve) from 0 to 1300 km/h to 1400 km/h (depending on the type of protective equipment), altitudes from 0 to 20000 m and Mach numbers up to 2.5.

The ejection seat is used in combination KKO-15 protective and oxygen equipment and the installation weight of the seat is less than 103 kg (including the parachute system, survival kit, emergency oxygen system and pyrotechnic charges).
