A small flying vehicle flown by radio control or autonomously by an auto pilot is equipped with an airbag device. The small flying vehicle has a main body part including a controller and a battery, a frame, a propeller, a motor, and a transmitting and receiving antenna. The airbag device has a gas supplier, a sensor, a controller, and an airbag. The airbag device is attached to the main body part, and the gas supplier is provided with a gas cylinder that releases a compressed gas when a closure member sealing the gas cylinder is broken, a breaker, including an electric igniter, that breaks the closure member, and introduction device that introduces the gas discharged from the gas cylinder and providing the pressurized gas into the airbag to inflate the airbag.

An airbag system includes a VTOL aircraft fuselage having an airbag compartment defined within the fuselage. A protective cover defines a portion of the exterior surface of the fuselage. The protective cover encloses at least a portion of the airbag compartment. An airbag is folded within the airbag compartment secured to a point on the fuselage. A method for deploying an airbag in an aircraft includes sending a signal to a gas generator to inflate at least one airbag secured within an airbag compartment within a fuselage of an aircraft. The method includes jettisoning off a protective cover from the airbag compartment. The method includes inflating the airbag with the gas generator to extend outside of the airbag compartment to attenuate forces and cushion the aircraft upon ground impact.

An aircraft includes; a plurality of rotor units each of which includes a propeller and a motor which drives the propeller, and generates thrust for flight of the aircraft; a controller which controls rotation of the propellers included in the plurality of rotor units; a balloon which laterally covers the plurality of rotor units; and a detector which detects a state of the aircraft, wherein the controller decreases a rotational speed of the propeller included in at least one rotor unit among the plurality of rotor units, according to a result of detection by the detector.

Occupant restraint systems for use in aircraft and other vehicles are described herein. In some embodiments, the occupant restraint systems include an under-seat airbag positioned below a seat cushion having a separation feature extending laterally therethrough. The separation feature enables a front cushion portion to move upwardly and away from a seat pan by a greater distance than a rear cushion portion upon inflation of the under-seat airbag, thereby favorably positioning the seat occupant's thighs relative to the seat occupant's torso.

Safety systems for unmanned vehicles are disclosed. An example vehicle includes a housing and a propulsion system supported by the housing. The propulsion system to generate lift. An anti-crash module is coupled to the housing. The anti-crash module has a compressible foam that is to deploy to protect the propulsion system from an impact.

An inflatable head restraint system for a parachute assembly may comprise an inflatable volume configured to inflate in response to a deployment of the parachute assembly. The inflatable volume may be located between a left shoulder riser and a right shoulder riser of the parachute assembly. A conduit may be fluidly coupled to the inflatable volume.

A life protection device system is proposed. More particularly, the life protection device system includes: a shock absorbing device provided with a shock absorbing part, a shock absorber, and an airbag that are mounted on a moving object so as to absorb impact to protect the life of passengers in a crash or collision of the moving object; a measuring device detecting the shock applied to the moving object; a controller generating a preset driving control signal according to the detected shock of the measuring device; and an artificial intelligence part notifying of an occurrence of a disaster and asking for help from a designated disaster center in response to the driving control signal of the controller, wherein the impact on the passengers is minimized even when the moving object such as a drone, autonomous aircraft, and autonomous vehicle crashes or collides, or falls into a river or sea.

A starting/generating system for an aircraft turbine engine, the starting/generating system comprising at least one brushless drive motor/generator, at least one control module and at least one power module, the power module being configured to supply/receive electric power from the brushless drive motor/generator, the control module being connected to the brushless drive motor/generator by a control cable in order to control its operation, in which system the power module is configured to be mounted in the housing of the non-pressurized zone so as to be located adjacent to the brushless drive motor/generator and the control module is configured to be mounted in a pressurized zone of the aircraft, the control module being connected to the power module by a two-way communication cable in order to control its operation.

In an embodiment an unmanned aerial vehicle comprises a central body and a plurality of support structures extending outwards from the central body. Each support structure supports a rotor blade assembly and is provided with one or more deformable portions. The rotor blade assembly defines a rotational axis of one or more rotor blades associated with the rotor blade assembly.

An aircraft cabin includes at least one seat able to receive at least one passenger; at least one table arranged opposite the seat; and a safety device able to be mounted on the table, below the table or received in the table. The safety device includes a deployable protection assembly including an airbag deployable from a retracted idle configuration to a deployed safety configuration, and a system for controlling the deployment of the or each airbag, able to trigger the deployment of the airbag beyond a threshold deceleration value of the aircraft.
