Housing for electronic device

In some examples, this disclosure describes a system for verifying identities of a first user and a second user. In some examples, the system includes processing circuitry and a memory device configured to store biometric verification data associated with the first user and the second user. In some examples, the system also includes an input device configured to receive biometric input data and transmit the biometric input data to the processing circuitry. In some examples, the processing circuitry is configured to determine whether the biometric input data matches biometric verification data for the first user or the second user, unlock the aircraft in response to determining that the biometric input data matches biometric verification data for the first user or the second user, and activate the aircraft for operation in response to determining that the biometric input data matches biometric verification data for the first user.

Different levels of access to aircraft based on biometric input data

A method and apparatus comprising a plurality of seating systems and a frame for use in a passenger aircraft. A first seating system in the plurality of seating systems may have different dimensions from a second seating system in the plurality of seating systems. A frame may be configured to be connected to the plurality of seating systems.

Aircraft seating systems

A jet noise suppressor including a nozzle having a front end and an opposed rear end, spokes extending radially inward from the nozzle, the spokes defining vents, and a center-body connected to the spokes and in fluid communication with the vents, the center-body being positioned centrally within the nozzle and including a closed front end and an open rear end, wherein the front end of the nozzle entrains a first ambient airflow passing through the nozzle and exiting the rear end of the nozzle proximate a periphery of the nozzle, and wherein the vents entrain a second ambient airflow passing through the center-body and exiting the rear end of the nozzle proximate a center of the nozzle.

Jet noise suppressor

A method and apparatus for controlling a propeller of a contra-rotation open fan (CROF) engine of an aircraft is provided. A diameter of the propeller is set to be at a first diameter during at least a portion of a first flight condition of the aircraft. The diameter of the propeller is set to be at a second diameter, different from the first diameter, during at least a portion of a second flight condition of the aircraft.

Optimization of downstream open fan propeller position and placement of acoustic sensors

A handrail apparatus and method for use with vehicles are disclosed. An apparatus in accordance with the teachings of this disclosure includes a first coupling plate to be coupled to a monument of a vehicle, a second coupling plate to be coupled to the monument of the vehicle. The apparatus includes a handrail coupled to the first coupling plate and a support coupled to the second coupling plate and the handrail. The handrail is movable between a stowed position and a deployed position.

Handrail apparatus for use with vehicles

An aircraft may include a cabin having a first portion, a second portion, a first ramp and a second ramp. The first portion of the cabin may include an upper deck and a lower deck. The upper deck and the lower deck may be disposed proximate to each other with vertical separation therebetween. The second portion may include an intermediate deck disposed in a plane that is substantially parallel to planes in which the upper deck and the lower deck lie. The intermediate deck may be vertically separated from both the upper deck and the lower deck. The first ramp may extend between the lower deck and the intermediate deck to provide access therebetween. The second ramp may extend between the upper deck and the intermediate deck to provide access therebetween.

Aircraft configuration with ramp access to multiple decks

A tire may include a tire body having an annular groove formed in a tread surface of the tire body. A plurality of spaced-apart studs may be located within the groove.

Studded tire and method of increasing tire traction

A propulsion system and methods are presented. A substantially tubular structure comprises a central axis through a longitudinal geometric center, and a first fan rotates around the central axis, and comprises a first fan hub and first fan blades. The fan hub is rotationally coupled to the substantially tubular structure, and the first fan blades are coupled to the first fan hub and increase in chord length with increasing distance from the first fan hub. A second fan is rotationally coupled to the substantially tubular structure and rotates around the central axis and contra-rotates relative to the first fan. Second fan blades are coupled to the second fan hub, and a nacelle circumscribing the first fan and the second fan is coupled to and rotates with the first fan.

Rotational annular airscrew with integrated acoustic arrester

A traction-on-demand landing gear tire control system and methods are presented. An outer tire of an aircraft wheel is depressurized to a depressurized state in response to a non-optimal aircraft landing condition. An inner tire of the aircraft wheel contacts the outer tire in response to the depressurized state, and a plurality of traction studs are deployed to protrude from the outer tire in response to the inner tire contacting the outer tire.

High traction on demand aircraft landing gear system

A method and apparatus for boarding an aircraft. Passengers may be lined up in a first line and a second line relative to a doorway for the aircraft. A flow of the passengers in the first line and the second line may be controlled through a corridor connecting the doorway to a first aisle and a second aisle in an interior of the aircraft. The flow of the passengers may pass through a number of spaces in the corridor. The number of spaces may be reserved for a number of crew members during an emergency operation in which the passengers exit the aircraft.

Dual boarding system for aircraft

An internal wall in an aircraft cabin separates a lavatory and a galley of the aircraft. The internal wall has an intermediate notch that increases a lateral width dimension of the lavatory above the notch and thereby improves the spatial environment of the lavatory.

Configurations provide rapid adjustment to an aircraft attitude in the water upon an emergency water landing. In one configuration, an aircraft fuselage has a forward compartment that includes a water intake and an air vent. The water intake is located below an expected waterline upon ditching the aircraft in water and transports a flow of water to the forward compartment at a designed flow rate. The air vent is positioned at a height in the forward compartment and allows a desired volume of water to fill the forward compartment and adjust an attitude of the aircraft within a time period.

Attitude control of an aircraft in a ditching condition

A method comprises continuously discharging a persistent vapor of bird repellant from a non-propulsion apparatus on a flying aircraft into an elevated airspace to substantially cover a runway flight path corridor at a commercial airport to prevent birds from striking subsequent aircraft in the corridor. The discharging automatically begins from a runway at the airport and automatically ends when the corridor is substantially covered.
