F-86 Ejection SEAT
간만에 F-86의 사출시트가 궁금해져서
찾아보았습니다.
예전에 군생활할때 시트 안쪽을 좀 자세히
살펴볼걸... 좀 후회되네요...

그래도 자료는 많습니다..^__^

우선 사진의 출처들은 사진 아래에 자막으로 달려있고 마우스를 올리면 출처를 보실수 있습니다.
사진들은 일부만 가져왔습니다.

우측사진의 시트가 F-86 사출좌석입니다.
다리 보호용 발판이 있습니다..

글을 읽어보시면 F-86 사출시트는 1세대형
사출시트라고 하네요...

1세대 사출시트도 함께 올려둡니다.

The F-86 Ejection seat is a good example of the first generation ejection seat.

Designed to do little more than keep the pilot in place in the aircraft, and toss him out, it was of little value below 1000 feet. The seat included a seat height adjustment that only differs from the currect style of office chair in the location of the handle. The seat height was adjusted by use of the lever to the right of the headrest and by removing the pilots weight from the seat to go up, or pushing down to lower the seat. The ejection sequence was complicated by the tight fit of the canopy and its low frame at the front.

Accordingly, after actuating the emergency O2 bottle, the pilot was to lower his head and pull up on the right handgrip to jettison the canopy. The canopy slid straight aft along its rails and then the pilot could sit upright and lock the harness with the left
handgrip. He then was to bring his feet back to
the footrests and brace his arms on the armrests. His head was to be pushed back against the headrest with his chin tucked in.

The ejection trigger under the handgrip was then squeezed. The seat catapult would fire and the seat would clear the aircraft.

The pilots connections to the aircraft were automatically disconnected by the connectors between the footrests. Once clear of the aircraft the pilot had to release his safety harness and kick away from the seat.
 
Then he had to manually activate his parachute once he had descended to a safe altitude.

The photos below show an F-86E seat manufactured by Canadair.

Generations of Seat Designs

First Generation - (1940-1965) These seats were purely ballistic operation with a compressed air, mortar, or rocket cartridge providing a single force to remove the seat and occupant from the aircraft. In early generation 1 seats, the occupant had to deploy the parachute manually. In later seats this became an automatic function. Examples of first Generation seats would be the Saab Mk 1 and the Martin Baker Mk 1-5 seats.

Second Generation - (1965-1975) Accumulated information had shown that a catapult alone would put too much force/acceleration on the occupant to survive an ejection without significant injury. Also, the end users of the seats were looking for zero/zero performance and performance at high speed. To accomplish this, a rocket sustainer was added. The catapult would operate from 0.15 to 0.25 seconds to keep the initial acceleration under 10G. The rocket sustainer would then act for an additional 0.20 to 0.40 seconds. The Martin Baker Mk 7 and the Douglas Escapac seats would be examples of this generation.

Third Generation - (1975-present) Automated features had been added to seats such as drogue chutes, parachute deployment based on altitude, and automatic deployment of survival gear since the first generation. But the advances in electronics allowed a computer to be placed into the seat and control the functions based on readings from sensors. Pitot - static systems, gyroscopic stabilizers, and pilot weight indicators were added to give information to the seat computer, extending the ejection envelope and improving crew survivability. Representative examples of the third generation are the Martin Baker Mk 14, The McDonnell Douglas ACES II, and the Stencil S4S.

Fourth Generation - (present) Research continues on expanding the envelope for the systems. Martin - Baker Aircraft, Boeing (McDonnell Douglas), and the former Soviet Union have either tested or placed into service seats featuring vectored thrust, flow generators, or variable thrust rockets.
