Aviation-Ejection 2편[사출]/Shoulder Harness Reel Assembly[하네스 릴 어셈블리]

Ejection Seat 사출 단계 [http://www.gallagher.com/ejection_seat/technical_aspects.htm]▽

위 사출 단계는 국내 사이트를 찾아보면 금방나오는 내용이라 간단하게만 찾아 올립니다.

Shoulder Harness Reel Assembly[하네스 릴 어셈블리] ▽
Shoulder Harness [안전벨트 릴] 이란 갑작스러운 충돌에 몸이 앞으로 튕겨나가는걸 방지하기 위해서 릴이라는 것이 lock을 걸어줍니다. 자동차 안전벨트와 같습니다. 실제로 팍당겼을때 락이 걸려야 정상입니다.
사출했을때는 사출시트 머리받침대 안쪽에 붙어있는 릴의 끈이 등받이서부터 엉덩이 아래 Survivor Kit 아랫쪽으로 이어져있는데 Reel이란것이 사출했을때 감아줌으로써 시트에서 조종사와 Survivor kit를 튕겨주는 역할을 합니다.

아래 내용은 어렵게 구한 Shoulder Harness Reel 구조T.O입니다.  하네스 릴의 구조는 이렇게 생겼고 사진은 구하는 대로 올려보도록 하겠습니다.
Shoulder Harness Reel Assembly With Automatic Reel Lock - Patent 4801105

SHOULDER HARNESS REEL.- The shoulder harness reel (fig. 5-8, view A) is fitted horizontally across the front faces of the main beams and serves as a center crossbeam for the main beams assembly, as well as a means of securing the upper harness. It ensures that the occupant will be brought to, and locked in, the correct posture for ejection. For normal flight operations, the shoulder harness is free to extend and retract as the occupant moves in the ejection seat. The shoulder harness control lever on the LH side of the seat bucket can be moved to the forward (locked) position, which will permit the

harness straps to retract but prevent them from extending. When in the normal unlocked state, automatic locks protect the occupant against rapid forward movement under high g-loading.

PARACHUTE DEPLOYMENT ROCKET MOTOR MK 122 MOD 0.- The parachute deployment rocket motor (PDRM) (fig. 5-9) is mounted on the LH main beam of the seat. When initiated by the sequencer, restraint release unit, or manual override (MOR) system, the PDRM extracts the personnel parachute from its stowage by means of a withdrawal line attached to the deployment sleeve.

The PDRM is a sealed unit. It consists of a cylindrical body that contains a gas-operated secondary cartridge in a breech at the lower end and a rocket with an integral gas-operated igniter cartridge in a barrel at the upper end. In a parallel connected chamber is an electrically initiated primary cartridge. A gas inlet is connected by a gas pipe to the harness release system.

Fitted around the rocket is a sliding stirrup, which is connected to the parachute withdrawal line and is free to slide down the rocket as it leaves the barrel.

ELECTRONIC SEQUENCER.- The NACES sequencer assembly (fig. 5-10) is composed of the sequencer, connectors to the interface with pitot static and dynamic pressure sources, and cable loom sleeving. It is mounted across the main beam assembly, below the parachute assembly. Upon activation, the sequencer determines the ejection mode and controls the functions of the drogue release, parachute deployment, and seat/man separation.
