Altitude Chamber Testing of the Passenger Oxygen System (POS)

AFRL711 HPWRHPG, Brooks City-Base TX conducted safe-to-fly testing of the CV-22 Passenger Oxygen System POS. The CV-22 is an unpressurized aircraft. POS is a self-contained, roll-onroll-off system to support passengers or paratroopers during high altitude operations and patients during medevac. POS includes a device for storing liquid oxygen, regulating the system pressure, and distributing oxygen to cargo area seats. POS is secured on the V-22 like cargo, has removable ballistic protection, and requires no aircraft modifications. One or two POS units can be installed in the CV-22 cargo area. The system successfully passed testing in the passenger, paratrooper, and medevac configurations. Two 2 POS units can support up to 20 passengers to 17,999 feet MSL, up to 16 paratroopers to 24,999 feet MSL, and up to 12 patients to 10,000 feet MSL.
