K-36D Ejection Seat Operation

The K-36D ejection seat provides emergency escape for a 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, and other 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 1,300 km/h (700 kn; 810 mph) to 1,400 km/h (760 kn; 870 mph) (depending on the type of protective equipment), altitudes from 0 to 20,000 m (66,000 ft) 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 (227 lb) (including the parachute system, survival kit, emergency oxygen system and pyrotechnic charges).

K-36D and K-36DM ejection seats are used on MiG-29 and Sukhoi Su-27 fighters.
