A hybrid composite-metal energy absorbing seat is described. According to one embodiment, an aircraft seat includes a seat base assembly and a seat back assembly. The seat base assembly includes multiple rigid metal seat base side frame elements joined by a lower seat pan, an energy absorbing element placed on the lower seat pan to deform and absorb downward energy in a crash, and a contoured seat pan whose sides extend past the seat base side frame elements and deform to absorb downward energy in a crash. The seat back assembly is attached to the seat base assembly and includes multiple rigid metal seat back side frame elements joined by a contoured composite seat back. The rigid metal seat back side frame elements absorb forward crash load energy by permanently deforming during a severe forward crash load. The contoured composite seat back provides design / aesthetic flexibility.

An aircraft for unmanned aviation is described. The aircraft includes an airframe, a pair of fins attached to a rear portion of the airframe, a pair of dihedral braces attached to a bottom portion of the airframe, a first thrust-vectoring (“T / V”) module and a second T / V module, and an electronics module. The electronics module provides commands to the two T / V modules. The two T / V modules are configured to provide lateral and longitudinal control to the aircraft by directly controlling a thrust vector for each of the pitch, the roll, and the yaw of the aircraft. The use of directly articulated electrical motors as T / V modules enables the aircraft to execute tight-radius turns over a wide range of airspeeds.

An aspirator for inflating an aircraft evacuation slide, emergency raft or other inflatable device includes a flexible, collapsible aspirator barrel that is inflated during operation to form a substantially rigid tube. According to one embodiment, the inflatable support member receives a flow of high pressure air directly from the aspirator injector nozzle assembly. According to another embodiment, the collapsible aspirator barrel receives a flow of high pressure gas directly from the high pressure inflation source. Because the aspirator barrel of the present invention is collapsible, the present invention occupies significantly less space when stored than an equivalent aspirator with a rigid aspirator barrel.

A method of automatically triggering an emergency buoyancy system (10) for a hybrid helicopter (20) having a fuselage (21), two half-wings (23, 23′), and two propulsive propellers (24, 24′). During the method, said emergency buoyancy system (10) is primed, and then if a risk of said hybrid helicopter (20) ditching is detected, two retractable wing undercarriages (28, 28′) are deployed, each wing undercarriage (28, 28′) being fastened under a respective half-wing (23, 23′) and being provided with at least one immersion sensor (16). Finally, if the beginning of said hybrid helicopter (20) ditching is detected, at least one main inflatable bag (11, 11′) 7B suitable for being arranged under such fuselage (21) and at least one secondary inflatable bag (12, 12′) suitable for being arranged under each half-wing (23, 23′) are inflated so as to ensure that said hybrid helicopter (20) floats in stable manner.

An emergency floatation system associated with a landing gear of a rotorcraft comprising at least a float unit and a raft module. The float unit is formed by a base and a float cover with an inflatable float being positioned therebetween. The raft module is formed with a raft compartment adapted to receive an inflatable raft in the packed condition thereof. The raft module is supported on the float by the base. The raft is adapted for inflation and deployment from the raft module independently of the float deployment.

A safety pre-impact deceleration system for a variety of conveyances includes a parachute structure formed from air bags inflated with gas. Alternatively, the parachute structure includes a canopy with orifices. Air spaces in the parachute structure or orifices in the canopy have adjustable and selective dimensions to control the operational parameters of the vehicle. The system includes sensors and rapid exposure rate cameras with continuous loop recording to measure operational parameters of the vehicle and to predict possible collision. Once a collision condition is detected, audio / video images are stored on storage media. The air bags are deployed and inflated. In addition to air bags constituting the parachute structure, a plurality of air bags are provided to be deployed external the vehicle to aid in a safe landing.

A crash attenuation system for an aircraft, the system having an airbag carried by the aircraft and inflatable generally adjacent an exterior of the aircraft. The airbag has at least one vent for releasing gas from the interior of the airbag. A first gas source is in fluid communication with the interior of the airbag for inflating the airbag with gas generated provided by the first gas source. A vent valve is provided for controlling a flow of gas through each vent, each vent valve being selectively configurable between an open state, in which gas can pass through the associated vent from the interior of the airbag, and a closed state, in which gas is retained within the interior of the airbag. A second gas source is provided for at least partially re-inflating the airbag after venting of gas through the at least one vent.

An emergency flotation device for crashed small airplanes which can be retrofited on most small airplanes as well as come preinstalled on new small airplanes, is self contained in a small container; has several independent triggering means; and has a visual as well as an RF beacon system integrated within to call for rescue.

An autonomous passenger module is releasably carried on a super-sonic aircraft, such as a military fighter jet, for carrying plural passengers on supersonic and near space flights. The passenger module is equipped with passenger service and life support systems to provide oxygen and the like, a parachute system, and a landing airbag or flotation aid system. The module remains mounted on the aircraft throughout a normal flight. In an emergency situation, the module separates from the aircraft by means of releasable connector elements and descends using parachutes. The module provides high passenger capacity at a low cost in a simple manner for commercial supersonic flights using an existing supersonic aircraft as a carrier platform.
