Abstract:
The disclosure refers to a propeller blade for an aircraft engine that includes an airbag system contained inside the blade and comprising at least one bag and at least one gas generator, the at least one gas generator in fluid communication with at least one bag for inflating the bag, a detecting system for detecting a rupture of a part of the blade, a trigger for activating the at least one gas generator when the rupture is detected by the detecting system, and the blade skin being configured for allowing the at least one bag to pass through the blade skin for being expanded outside the blade upon the bag inflation by the gas generator.
Abstract:
A protection system (15) includes an inflatable bag (16) connected to inflation elements able and intended to be activated so as to inflate the inflatable bag in the event of and/or upon the prediction of an impact. The inflatable bag (16) has a substantially annular overall shape when inflated. Such a protection system (15) is advantageously intended to protect the passengers in a helicopter.
Abstract:
Electronics module assemblies (“EMAs”) for inflatable personal restraints and associated systems are described herein. An EMA configured in accordance with an embodiment of the present technology can include, for example, a housing having a body portion, cover portion that attaches to the body portion to form an enclosure, and protrusion extending outwardly from the cover portion. The protrusion can have an outer boundary at which the protrusion projects away from the cover portion. The EMA can further include a crash sensor within the enclosure in an area defined by the outer boundary of the protrusion. The protrusion can form an envelope of space around the crash sensor that defines a minimum distance an external object with a magnetic field can come to the crash sensor without activating it. The EMA can optionally include a magnetic field configured to disable the crash sensor upon the detection of an external magnetic field.
Abstract:
A system for testing a number of electronic module assemblies (EMAs) that control one or more personal restraint systems. A programmed processor with a computer system transmits signals that instruct the EMAs to perform a diagnostic self-test. The results of the self-test are received by the computer system and stored in a computer readable memory. In one embodiment, the computer system is a cabin management computer system for use on an aircraft.
Abstract:
Structure mounted airbag assemblies and associated systems and methods are described herein. An airbag system configured in accordance with an embodiment of the present disclosure can include, for example, a housing having a cavity and an opening in communication with the cavity, an airbag assembly within the cavity, and an inflator operably coupled to the airbag assembly. The airbag assembly can include an airbag configured to deploy through the opening of the housing during a crash event. The airbag system can further include a door removably positioned across the opening and configured to move away from the opening during airbag deployment. The housing can be affixed to an interior portion of an aircraft, forward of and offset from an aircraft seat.
Abstract:
An unmanned air module includes one or more rotors, engines, a transmission and avionics. Any of several different ground modules may be attached to the air module. The air module may fly with and without the ground module attached. The ground module may be a vehicle ground module and may be manned. The vehicle ground module may transport the attached air module across the ground. The air module may have two rotors, which may be ducted fans.

Abstract:
An apparatus comprising a float bag comprising an air bladder configured to inflate when an aircraft lands in the water, a girt coupled to the air bladder and configured to attach the air bladder to the aircraft via at least one airframe fitting, and a load attenuator coupled to the girt and configured to be positioned between the girt and the airframe fitting when the float bag is attached to the aircraft.
Abstract:
An inflatable shoulder harness assembly for an aircraft seat including a shoulder belt, a retractor, an airbag contained within an outer cover, and a belt guide slideably receiving the inflatable airbag and outer cover therein when the shoulder belt is retracted, the belt guide defining an elongate channel for facilitating free movement of the outer cover during belt fastening and retraction. The assembly further includes an exit bezel for finishing the look of the seat and a stiffening element for preventing kinking, bunching and twisting of the outer cover.
Abstract:
An aircraft (11) with at least an inflatable device (41) installed in a cavity (21) in its external surface which is equipped with a door (25) for opening/closing said cavity (21) is provided. The inflatable device (41), comprising a cushion (45) and a gas generator is configured for filling the cavity (21) with the cushion (45) when it is inflated with the gas supplied by said gas generator, without protruding from the cavity (21) for reducing the downstream air flow disturbances generated by said cavity (21) when the door (25) is open. The inflatable device (41) includes control means for inflating the cushion (45) in predetermined circumstances, being the door (25) open. The invention is particularly applicable to the cavities of the Main Landing Gear (31) for avoiding power losses to a Ram Air Turbine (51) placed behind it.
