Abstract

A system containing a sensor suitable for pilot respiration inhalation gas data collection and a sensor suitable for pilot respiration exhalation gas data collection can be interfaced to a host computer or operate autonomously. The system or sensor components thereof can be used as a research tool for in-flight monitoring of physiologic effects on pilots' performance caused by the unique conditions faced during flight, in addition to human factors engendered during the course of their duty (fatigue, sleep loss, etc.).

Abstract

A pressure vessel including a boss, liner, and shell to create a vessel capable of storing high-pressure fluids with minimal weight. The boss includes a through aperture and at least one recess to receive at least one fastener. The liner includes an interior surface, an exterior surface, and an annular insert to receive the fastener(s). The interior surface defines an interior cavity of the pressure vessel. The liner is configured to secure the boss to its exterior surface using the fastener(s) and the annular insert. After securing the boss to the liner, the composite wrap is applied to the boss and liner so as to surround the liner and at least a portion of the boss.

Abstract

Disclosed is an inflator assembly. The assembly operates by puncturing a diaphragm of an associated container to thereby releasing a volume of pressurized gas. The pressurized gas, in turn, is used to inflate an article, such as a life raft. The inflator assembly is adapted to be either manually or automatically actuated. The various details of the present disclosure, and the manner in which they interrelate, are described in greater detail hereinafter.

Abstract

Disclosed is an inflatable article that is designed to be launched to an intended target. The article is launched by a gun in an un-inflated state and inflates upon contacting water. The target can be, for example, a person being rescued. The article is initially stored in an outer layer of material. The outer layer of material may be shrink-wrap or a foam layer. The outer layer permits the article to be retained in a compact configuration prior to being launched. This, in turn, allows the article to be launched over great distances. The outer layer is designed to rupture upon inflation of the article.

Abstract

An adapter for converting a full size aircraft bomb rack into a rack capable of supporting reduced size bombs or stores. The full size bomb rack includes a bomb ejection mechanism capable of delivering an ejection force to a full size bomb. The adapter includes an elongated plate having a body portion defining a planar center portion and end portions. The end portions include laterally extending sway braces for reducing lateral swaying of the reduced size store or bomb. The adapter plate is mounted between the reduced size store and the full size adapter rack. The body portion of the adapter rack includes apparatus for ejecting a reduced size store from the elongated plate. A first opening is arranged adjacent to one end portion of the elongated plate for receiving fasteners carried by the reduced size store which attach the store to the full size bomb rack. These fasteners are passed through an opening in the elongated plate. An ejection mechanism at an end of the elongated plate operates to transfer the ejection force from the full size bomb rack to the store.

Abstract

An electromechanical valve assembly for controlling oxygen flow from a compressed oxygen source in an aircraft includes: a valve housing, an inlet, an outlet, a passageway allowing flow of oxygen from the inlet to the outlet, a spring-biased conical poppet movable within the passageway; a spring-biased pressure regulating piston engagable with the conical poppet to maintain it in an open position, a push rod engagable with the conical poppet to maintain it in a closed position, and a movable seat in the passageway that engages the conical poppet to regulate gas flow through the passageway. Actuation of an electric motor assembly to cause the seat to move upward results in closing of the valve assembly and shutting off of the oxygen flow. Actuation of the motor assembly to cause the seat to move downward results in opening of the valve assembly and regulation of the oxygen flow.

Abstract

An emergency oxygen system includes a pressure vessel containing pressurized oxygen, a rupturable seal that confines the oxygen within the vessel until the seal is ruptured, and a valve assembly for controlling the oxygen release and delivery to an aircraft passenger The valve assembly includes a valve body with an oxygen outlet connected to the pressure vessel, and a threaded poppet mounted within the valve body whose first end is a pierce point in contact with the seal The system further includes a pulley that is rotatably connected to the valve body and engages the second end of the poppet, a cable attached to the pulley to effect its rotation, and an oxygen breathing mask connected to the oxygen outlet
