Parachutist High Altitude Oxygen System (PHAOS)

HDT Airborne Systems designs and manufactures the Parachutist High Altitude Oxygen System (PHAOS) certified by the US Military to meet mission requirements for high altitude jumps. PHAOS has been tested by NASA, the U.S. Army Soldier Systems Center (SSC), and NAVAIR and has been certified to operate at altitudes up to 35,000 ft MSL. OXCON, the eight-, six-, or two-man OXygen CONsole which supplements the man-mounted PHAOS system, has been in use worldwide for more than 25 years.

The PHAOS system integrates an MBU- 12P mask with an automatic diluter/demand regulator (as opposed to a constant flow system) to maximize the effective use of oxygen with regard to mission objectives and individual user requirements. PHAOS has been tested by NASA, The U.S. Army Soldier Systems Center (SSC), and NAVAIR and has been certified to operate at altitudes up to 35,000 ft MSL.

Meeting the Challenges for High Altitude Parachutists

• PHAOS automatically adjusts the mix of oxygen and ambient air to ensure optimal use of oxygen supply for the jumper when reaching high altitudes up to 35,000 ft MSL.
• PHAOS provides 100% oxygen when connected to a pre-breathing oxygen console and programmed dilution when breathing from the individual oxygen supply.
• The mask-mounted dilution port and exhalation valve allows the user to breathe comfortably throughout total descent, even after all oxygen is consumed and provides facial protection from brush during landing.
• PHAOS eliminates hoses and connectors on the front torso providing the parachutist with a “clean front” to improve vision and mobility.

PHAOS Optional Equipment

• Selection of different bottle capacities to increase duration.
• Mask integrated communications (microphone).
• Helmet with fiberglass hard shell, rigid foam insert and bayonet receptacles.
• Helmet integrated communications (headphones).
