Ejection seat К-36D-3,5 (К-36D-3,5М)

Purpose:

The К-36D-3,5 ejection seat serves as a working station for a pilot and a means of emergency escape from an aircraft by ejection.

The ejection seats of the К-36-3,5 family are designed to be used as a part of the emergency escape system for single-seat and two-seat combat/combat & training aircraft.

Design description:

In flight, a crewmember is held in the seat with a suspension/restraint harness system. The crewmember may be restrained in the seat with the shoulder and waist restraint mechanisms. The seat features stepless height adjustment, which makes the seat occupation comfortable for work and vision.

The crewmember protection against the dynamic pressure G-loads at ejection is provided with the protective gear, windblast shield, forced restraint in the seat, seat stabilization as well as the selection of one of three operation modes for the energy source depending on the suited pilot mass. At the aircraft speed exceeding 850 km/h, the MRM steady-state mode is adjusted by the automatics depending on the acceleration.

After automatic separation of the pilot from the seat, the recovery parachute canopy is inflated providing the pilot’s safe descent. A portable survival kit, which is separated from the seat together with the pilot, supports his/her vital functions after landing or water landing, makes the pilot search easier, and the ПСН-1 life raft supports the pilot floatation on the surface of water.

Specifications:

The К-36D-3,5 ejection seat realizes the crewmember emergency escape within the range of equivalent airspeed (VE.) from 0 to 1300 km/h, at Mach number up to 2.5 and aircraft flight altitude from 0 to 20,000 m, including takeoff, landing run and «Н=0, V=0» mode. The seat is used with the KKO-15 set of protective gear and oxygen equipment.

The seat installation mass does not exceed 103 kg, including the survival kit.

Year of development: 2001

Application:

The К-36D-3,5 family features seat modifications for each aircraft version.

The К-36D-3,5 seats are installed in all versions of the Su-30 aircraft; the К-36D-3,5M seats are installed in the MiG-29M and seaborne МiG-29К/KUB aircraft.

The К-36D-3,5E ejection seats are supplied to India, Vietnam and Algeria.
