Pipe threads shall conform to FED-STD-H28/8. 3.6 Design and construction, The rigid seat survival kit (RSSK) shall be designed and oriented in such a manner as to accommodate and provide a maximum of comfort,
29、 convenience, and freedom from hazard for the aircrewman (lower limit 3 percentile man, upper limit 98 percen- tile man, as specified in ACEL Report No. 533). The seat kit shall be designed or oriented in such a manner as to integrate satisfactorily with the airframe, seat, and aircrewmans personal
30、equipment. The seat kit shall be designed to accommodate the applicable survival equipment within the configuration envelope. The seat kit shall be designed such that any hardware, handles, or other equipment protruding above the seat kit shall not cause pressure points or discomfort to the aircrewm
31、an during service usage, ejection, or possible crash loads. The container shall provide attachment to the aircrewmans torso harness such that it will stay with the aircrewman during ejection and fall. The seat kit when installed in the seat shall be compatible with the in-service adjustment of the s
32、eat and maintain the in-service pilots eye reference level requirement and accommodate the 3 to 98 percentile aircrewman. As a design goal, in aircraft where the in-service adjustment of the ejection seat is physically limited by the anthropometry of the 3 or 98 percentile aircrewnan, the i . . f Pr
33、ovided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-design of the seat kit shall compensate, where possible, the adjustment limitations on the ejection seat to allow for full-up and full-down adjustment of the seat to the eye reference level. Such a design
34、 would require the approval of the Naval Air Systems Command. The optimum design of the RSSK shall be such that the components affecting the ejection seat to RSSK and torso harness restraint subassembly shall confom to the general arrangement shown in figure 1. 3.6.1 Operation. The rigid seat surviv
35、al kit shall be designed to allow the following operations: a. Removal of the kit from the aircraft for servicing, packing, etc., without the use of special tools for detaching or attaching service lines from the aircraft to the kit and without repacking the container. b. Normal abandonment of the a
36、ircraft after a flight, leaving the RSSK in the aircraft by actuating the quick release fittings of the restraint subassembly from the torso harness. c. Ejection with subsequent manual release of the release handle causing the bottom container to separate and fall away from the contoured container l
37、id secured to the aircrewman. The bottom container as it falls to full line stretch actuates the inflation system of the life raft causing it to inflate. The raft and survival equipment shall be secured to the aircrewman by means of the dropline which is connected to the container bottom and to the
38、container lid. The manual release shall operate with an upward pull on the release handle releasing the container bottom from the container lid and aircrewman. 3.6.2 Components. Unless otherwise specified, the rigid seat survival kit shall consist of the following components: a. Basic container. b.
39、Comfort cushion. subassembly. c. Ejection seat to RSSK and torso harness restraint d. Release handle and container locking mechanism. e. Container dropline. f. Radio beacon bracket. 3.6.2.1 Basic container. The container shall be designed to The provide basically a cushioned seat conforming to the d
40、imensions and general design as specified in the applicable detail specification. container shall provide a maximum of interior space consistent with the limitations and requirements as specified herein and the physical limitations Provided by IHSNot for ResaleNo reproduction or networking permitted

The basic container shall be composed of two parts consisting of the contoured container lid and a container bottom with means for locking and releasing the lid as specified in the detailed specification. surfaces shall be accurat
42、e to a degree that shall permit the proper function of the unit within the environmental conditions expected during the service life of the unit. The fit of the assembled components shall be such that upon actuation of the release handle, the container bottom shall separate and fall away easily from
