An air mobility control system is provided. The system includes one or more shock absorbing units that are mounted in an aircraft and are configured to absorb a vertical force impacting on the air mobility vehicle. A distance sensor is mounted in the air mobility vehicle and is configured to sense the distance to a ground or an approaching object. A safety controller is configured to detect an abnormal descent of the air mobility vehicle and to operate the one or more shock absorbing units to be deployed according to the distance sensed by the distance sensor.

A hydraulic system 300 for an aircraft including a backup hydraulic pressure source 216 to provide hydraulic pressure to a brake 222 in the event of a failure condition of a primary hydraulic brake pressure source. The hydraulic system 300 also includes a landing gear backup system to provide hydraulic pressure to enable extension and/or retraction of landing gear 100. The backup hydraulic pressure source 216 is arranged to provide hydraulic pressure to the landing gear backup system in the event of a failure condition of a primary landing gear hydraulic pressure source.

An aircraft emergency landing stability system includes an aircraft a fuselage and landing gear, and a landing stability apparatus coupled to the fuselage, wherein the landing stability structure mitigates a nose-down pitching moment of the aircraft created in response to contact with a landing surface during an emergency landing.

An actuator assembly includes an actuation member, a release member, and a source of pressurized gas, wherein during a normal mode of operation, the actuation member and the release member are engaged to move in unison, and wherein during an emergency mode of operation, pressurized gas automatically decouples the actuation member from the release member to move separately. In accordance with yet other aspects of the present disclosure, an electro-mechanical actuator includes an electro-mechanical drive system and an integrated backup system operated by a gas generator, wherein when the backup system is activated, the electro-mechanical drive system is decoupled and the actuator moves to a predetermined position and mechanically locks in place.

A deployable aircraft flotation system. The deployable aircraft flotation system includes a pair of flotation members. The pair of flotation members are positioned on opposing sides of a bottom surface of an aircraft body. Each flotation member of the pair of flotation members has an inner layer that is made of a first buoyant material, an outer layer that is made of a second buoyant material, and a middle layer between the inner layer and the outer layer that is made of a rigid material. The flotation members can be moved from a stowed position, where they are stored in housings, to a deployed position, where they emerge and are positioned on the bottom of the plane.

An emission-capturing apparatus includes a tank having an inlet and an outlet. The apparatus further includes a muffler fluidly coupled with the outlet to intercept fluid exiting the outlet, permit passage of gas through the muffler, and inhibit passage of liquid through the muffler. The apparatus further includes a hose having a tank end and a coupler end. The tank end is coupled to the inlet. The apparatus further includes a coupler coupled to the coupler end of the hose. The coupler has a drain hole. The coupler is configured to be coupled to a surface having an ejection port, to completely cover the ejection port when the coupler is coupled to the surface and to support the coupler end of the hose in a position to receive an emission when the drain hole is aligned with the ejection port.

Described are systems and methods for a nacelle auxiliary landing gear to be utilized as an alternative landing gear in the event of main landing gear non-deployment. The systems described herein include a nacelle auxiliary landing gear that includes a nacelle auxiliary landing gear strut and a nacelle auxiliary landing gear wheel, coupled to the nacelle auxiliary landing gear strut, wherein at least a first portion of the nacelle auxiliary landing gear wheel is configured to be disposed outside of a nacelle of an aircraft propulsor. The nacelle auxiliary landing gear strut is coupled to a core engine. Techniques for use of the nacelle auxiliary landing gear are also described herein.
