An aircraft air distribution assembly providing integrated personally controllable air flow and cabin air flow is presented. The aircraft air distribution assembly comprises a plenum and a flow restriction system. The plenum is connected to a plurality of personal air outlets configured to provide the personally controllable air flow. The flow restriction system extends through at least one wall of the plenum, the flow restriction system configured to set a pressure for the cabin air flow.

Anti-fogging systems for air-cooled, piston powered single engine aircraft which effectively prevent windshields from fogging during cold weather by directing a forceful stream of unheated, ambient air in a direction which intercepts exhaled air from an aircraft occupant to impede the moist exhaled air from directly reaching the windshield and condensing on the windshield. The disclosed systems keep the windshield of a small air-cooled, piston powered single engine aircraft from fogging while permitting a pilot to perform his pre-flight preparation, taxi and takeoff in cold climates.

An aircraft outflow valve with a heat exchanger is disclosed herein. The aircraft outflow valve can include a heat exchanger that includes an air flow path. Air can flow through the air flow path and exit the outflow valve through an opening at the end of the air flow path. Such airflow can regulate the internal pressure of the aircraft and can also dissipate heat from the outflow valve. The outflow valve can further include a liquid coolant flow path. The liquid coolant flow path can be coupled to liquid coolant lines of electronics of the aircraft. Thus, heat from the electronics of the aircraft can be dissipated through heat transfer between the coolant and the outflow valve, which is accordingly cooled by the airflow through the heat exchanger.

Apparatus and methods for providing a desired volumetric conditioned airflow rate and for reducing noise level, airflow recirculation and airflow separation are disclosed. An example apparatus includes a nozzle housing having a pair of opposing sidewalls and a front and back wall that define an airflow passage. The airflow passage has a centerline extending between the inlet and the outlet and has a plurality of cross-sections taken perpendicular to the centerline that collectively define a smooth contour along a length of the airflow passage. The cross-sections each have a thickness between the front and back wall that is greater at side edges than at the centerline. The thickness of the cross-sections decreases along a length of at least a first portion of the nozzle housing. A width of each of the cross-sections between the sidewalls increases along the length of at least the first portion of the nozzle housing.

An overhead aircraft passenger service unit, which is configured to be placed above the passenger seats within an aircraft cabin, comprises at least one cavity for housing at least one oxygen mask and at least one removable cover, which at least partially covers an opening of the cavity. The removable cover houses and/or supports at least one functional component.

Disclosed is a stowable airflow diverter for removable attachment to a floor vent of a turbine aircraft. The air diverter comprises vertical ducting extending from a base. A flexible gasket and magnets are attached to the base for engagement with the floor vent. A nozzle attached to the vertical ducting redirects the airflow emanating from the floor vent from horizontal to vertical in order to direct air conditioned air into the cock pit of the aircraft. In an alternate embodiment, the nozzle is rotatable with respect to the vertical axis of the duct. In another alternate embodiment, the nozzle and vertical duct comprise telescoping segments such that the device can be collapsed into the floor vent.

A gas turbine engine is disclosed having a tip clearance control system. The tip clearance control system has a cabin blower system, a casing arranged in use about a rotor of a gas turbine engine and a fluid delivery passage. The cabin blower system having a cabin blower compressor arranged in use to compress fluid used in a cabin of an aircraft and to compress fluid conducted via the fluid delivery passage into heat exchange with the casing.

A service trolley for inspecting an interior cabin of a vehicle including a plurality of seats is disclosed. The service trolley includes a container body supported by a plurality of wheels, at least one image capture device, and a control module in communication with the image capture device and a database. The image capture device is mounted to the container body and is positioned along an outer surface of the container body in a location relative to the interior cabin of the vehicle to view the plurality of seats. The database stores image data of the plurality of seats of the vehicle. The control module executes instructions to compare the image data stored in the database with the image of a specific seat to determine a presence of at least one defect on an exterior of a specific seat in the interior cabin of the vehicle.

A direction controlled service apparatus may include a mounting assembly, a housing assembly configured to operably connect to the mounting assembly, the housing assembly being movable with respect to the mounting assembly, and a plurality of actuators connected between the mounting assembly and the housing assembly, each actuator of the plurality of actuators being configured to contract upon a current being applied to the actuator to rotate the housing assembly with respect to the mounting assembly.

An apparatus for locational aiming of an overhead directional service unit includes a body including a first end configured to be matingly engaged with a housing assembly of the overhead directional service unit and a second end longitudinally opposed to the first end. A light source is disposed within the body and operable to project a light beam from the second end in a direction defined by a longitudinal axis of the body. With the first end matingly engaged with the housing assembly, pivotal movement of the body about a pivot axis relative to a mounting assembly of the overhead directional service unit applies a leverage force to the housing assembly to pivotally reposition the housing assembly relative to the mounting assembly so that the housing assembly is directionally aimed toward a target location visually indicated by the light beam.
