isolated such that heat and flammable fluids or gases cannot enter the converter
*
area. Other equipment components that may be located nearby, but not physically
separated shall be qualified to an explosive atmosphere. Converters, associated
plumbing arid heat exchanger(s) shall be located and installed to maximize
survivability during survivable crash landings. All components including
converters filled with LOX shall be installed to withstand a crash loading, g
level and pulse duration, applicable to that component and the aircraft for which
it is intended.
3.5.7 Drawings and data.
3.5.7.1 Drawings, Drawings should include the following and shall be in
accordance with DOD-STD-100.
3.5.7.2 Pre-engineering information. At least 60 days prior to the
preparation of the installation drawings, a schematic diagram of the oxygen system
and oxygen duration calculation, for specified mission profiles, shall be
submitted to the acquiring activity. The oxygen duration calculations shall
include data to show that the number of converters provided is sufficient for the
performance of the aircraft. The symbols used on all schematic drawings shall be
in accordance with Figure 1.
3.5.7.3 `Installation drawings. All installation drawings for oxygen equipment
shall be submitted to the acquiring activity for approval. Installation drawings
shall show the position of the equipment in the aircraft and the possible stations
in the aircraft. Installation drawings shall also show accessibility of
replaceable converters and filler valves.
3.5.7.4 Pilot's flight operating handbook data (for Air Force use). A
schematic drawing of the oxygen system and oxygen duration tables shall be
provided as required in the Pilot's Flight Operating Instructions Handbook in
conformance with Manual, Technical, Organizationl Maintenance Instructions. The
drawing shall include a plan view of the aircraft and shall include all items for
which there is a symbol in MIL-STD-17, Part 2. The drawing shall include the
symbol key listing, where applicable, and the type number of items. The symbols
used on all schematic drawings shall be in accordance with Figure 1 (see 6.3).
3.6 Major system components.
3.6.1 Converter selection and installation. The liquid oxygen converter, with
appropriate indicators, shall be selected from Table V and be based upon the
converter capability to support the specified number of crewmembers and based upon
the parameters set forth in 3.5.1 for indicators. Space shall be provided in the
aircraft based on the maximum converter specification envelope dimensions. If two
or more converters are installed in the aircraft, they should be separated as much
as practicable to minimize combat vulnerability. Sufficient space shall be
available to replace converters and perform maintenance on all parts. The
installation shall also provide for replenishing the liquid oxygen supply by
connecting 'an external filling source directly to the filling valve(s). The
filling point(s) shall be located such that the time for gaining access for
connecting the external filling source shall not exceed one man minute and shall
not create a hazard for servicing personnel.
