A life preserver head restraint may be configured to inflate in response to deployment of a parachute assembly. The life preserver head restraint may comprise an inflatable volume and a charge tank fluidly coupled to the inflatable volume. In an inflated state, the life preserver head restraint may restrict head movement during line stretch of the parachute assembly.

Described is a release system for inflatable life saving devices, such as evacuation slides, evacuation slide/rafts, emergency floats, emergency flotation systems, and life rafts. The release system incorporates an energy storing device and a securement system that can be released upon activation. Once the release system is activated, the securement system is opened to allow deployment of the inflatable.

A wireless dual flight data recorder apparatus and wireless network method using satellite communications for providing remote data redundancy, location accuracy, and real-time access to live flight data contained in the black box of an aircraft. An integrated GPS receiver uses the NAVSTAR GPS Precise Position Service allowing emergency responders immediate access to exact location of the device. A data collection algorithm streams flight data to a remote data center, performs data compaction for decreasing bandwidth, and data encryption for security prior to transmission to a remote data center. An ejection sensor system signals a second unit to eject milliseconds before impact reducing shock to the recorder. A flotation system allows the device to float on water, a solar panel extends the life of the batteries, and VoIP video camera recorder allows remote surveillance. The invention protects critical flight data and passengers ensuring expeditious rescue missions for survivors and investigators.

An aspirator includes an aspirator body having at least one flapper door designed to allow intake of a gas from an environment of the aspirator. The aspirator also includes an aspirator barrel having an end tip, a compressible spring, and a fabric positioned about the compressible spring, and designed to extend in response to receiving the gas and to transfer the gas from the aspirator body to the inflatable flotation device. The aspirator also includes a gas valve designed to receive a fluid from a compressed fluid source. The aspirator also includes a nozzle positioned within the aspirator body, coupled to the gas valve, and designed to receive the fluid via the gas valve and to direct at least a portion of the fluid towards the aspirator barrel such that the at least one flapper door allows the gas to flow from the environment into the aspirator barrel.

An aspirator may comprise an aspirator body defining an air channel and an inlet. A flow straightener may be disposed at the inlet. The flow straightener may be configured to produce a laminar flow through the air channel. An aspirator barrel may be coupled to the aspirator body and may define an outlet. A static airfoil assembly may be disposed at the outlet. The static airfoil assembly may be configured to produce a vortex flow exiting the aspirator barrel.
