Location of Crew and Passenger Oxygen Masks, Portable Oxygen System, and Protective Breathing EquipmentARP6390 (Current)08/10/2021
Various emergency situations may require the dispensing of oxygen to all occupants of aircraft during flight. During an emergency event, depending on the aircraft operational flight capability, all cabin occupants must be serviced by a mask presentation system connected to an operational oxygen source. Several regulations specify the functional characteristics and requirements of the oxygen systems for aircraft in support of different missions. These should be referred to for the exact functional performance requirements. It is not the intent of this document to ensure conformance with these regulations, but only to recommend general concepts for the location of the oxygen masks and oxygen system outlets for proper accessibility by the aircraft occupants, whether cabin occupants or crew members. Different requirements may apply when the mission of the pressurized aircraft or the operational altitude of the aircraft is not in excess of FL250. When the aircraft is operating above FL100

Material Gradients in Oxygen System Components Improve SafetyTBMG-1014206/01/2011
Oxygen system components fabricated by Laser Engineered Net Shaping™ (LENS™) could result in improved safety and performance. LENS™ is a near-net shape manufacturing process fusing powdered materials injected into a laser beam. Parts can be fabricated with a variety of elemental metals, alloys, and nonmetallic materials without the use of a mold. The LENS™ process allows the injected materials to be varied throughout a single workpiece. Hence, surfaces exposed to oxygen could be constructed of an oxygen-compatible material while the remainder of the part could be one chosen for strength or reduced weight. Unlike conventional coating applications, a compositional gradient would exist between the two materials, so no abrupt material boundary exists. Without an interface between dissimilar materials, there is less tendency for chipping or cracking associated with thermal-expansion mismatches.

Miniature Distillation Column for Producing LOX From AirTBMG-2672610/01/2006
The figure shows components of a distillation column intended for use as part of a system that produces high-purity liquid oxygen (LOX) from air by distillation. (The column could be easily modified to produce high-purity liquid nitrogen.) Whereas typical industrial distillation columns for producing high-purity liquid oxygen and/or nitrogen are hundreds of feet tall, this distillation column is less than 3 ft (less than about 0.9 m) tall. This column was developed to trickle-charge a LOX-based emergency oxygen system (EOS) for a large commercial aircraft.

Oxygen-Partial-Pressure Sensor for Aircraft Oxygen MaskTBMG-144809/01/2003
A device that generates an alarm when the partial pressure of oxygen decreases to less than a preset level has been developed to help prevent hypoxia in a pilot or other crewmember of a military or other high-performance aircraft. Loss of oxygen partial pressure can be caused by poor fit of the mask or failure of a hose or other component of an oxygen-distribution system. The deleterious physical and mental effects of hypoxia cause the loss of a military aircraft and crew every few years.

Breathing Apparatus Stores Cold Supercritical AirTBMG-3003611/01/1999
The supercritical air mobility pack (SCAMP) is a prototype self-contained breathing apparatus designed for use in rescue and fire-fighting operations (see figure). The SCAMP is based on the storage of air at supercritical pressure in a temperature range slightly above that of liquid air. Like breathing apparatuses based on the storage of liquid air ("liquid-air packs," for short), the SCAMP offers the advantages of compactness and light weight. In addition, the SCAMP offers the following advantages, as explained below:

Influence of Two-Hour Oxygen Prebreathe on the Decompression Sickness Incidence at Pressures of 145, 198, and 220 mm.Hg96142007/01/1996
Oxygen prebreathe (PB) before decompression eliminates dissolved nitrogen and therefore decreases the risk of decompression sickness (DCS) in aviators and astronauts. Factors that effect tissue perfusion, such as body position, temperature and exercise are known to increase denitrogenation kinetics during oxygen breathing. Only two hours of ground level denitrogenation, with light exercise (oxygen consumption 0.3-0.4 1/min) prior decompression from 760 to 220 mm Hg are enough to protect 70 sitting subjects against severe DCS during 4 hour simulation of extravehicular activity (with oxygen consumption 1.0-1.5 1/min) at off-nominal pressure mode. However, two hours of oxygen prebreathing are not enough to protect 30 test subjects against DCS during 2 hours exposure with metabolic rate (MR) 5-8 kcal/min (oxygen consumption 1.0-1.5 1/min) at emergency pressure level 145 and 198 mm Hg. In this case severe bends occurred after 30 minutes of exposure at this emergency pressure mode. The on
