Abstract: A calibration and verification system and method for dynamically controlling sequential delivery of mixtures containing a fire suppression agent to detection locations to simulate an agent discharge during a flight operation of an aircraft and for allowing direct monitoring of the concentration amounts at the detection locations to adjust a testing operation accordingly. Each of the mixtures is prepared with a precise concentration amount of the agent. The system and method include a remote test sequence unit for determining an optimal testing time period during a flight operation to remotely control the discharge and monitoring of the agent. Prior to the optimal testing time period, an airflow at an altitude of the flight operation is drawn through each of a plurality of detectors to tare out the characteristics of a surrounding environment using a processor, thereby establishing a measurement baseline for each of the plurality of detectors.

Abstract: An emergency oxygen system for aircraft passengers includes a hermetically welded sealed oxygen cylinder of stainless steel, a welded metal diaphragm sealing a discharge port and an extended hermetically sealed capillary tube for charging the cylinder with pressurized oxygen. A hollow piston cutter is driven to pierce the metal diaphragm as part of a first passageway delivering oxygen to the passenger. A second passageway delivers any leaking oxygen to a release port when the piston cutter is in position. A method of filling the cylinder includes welding to the cylinder a member having a metal diaphragm of a predetermined rupturable characteristic and using the open capillary tube to fill oxygen in the cylinder and subsequently crimping a portion of the capillary tube to provide a hermetic seal. A pressure gauge can be hermetically sealed to the bottom of the oxygen cylinder.
