A galley cart system employs a dry ice compartment and a refrigeration compartment in a galley cart in flow communication with the dry ice compartment. A ventilation system is in interruptible flow communication with at least the refrigeration compartment and configured to receive gas discharged from at least the refrigeration compartment.

A fluid flow restrictor device for controlling fluid flow at a connection between ducts may include a restrictor device body that is partially or fully inserted into and disposed within one of the ducts and an outboard restrictor device flange extending radially outward at an outboard end of the restrictor device body and having an outboard flange outer diameter that is greater than an inner diameter of the ducts so that the restrictor device body or the outboard restrictor device flange is engaged by an open end surface of the duct to prevent full insertion of the fluid flow restrictor device into the duct. A body inner surface defines a restrictor opening through the restrictor device body that can be varied to achieve desired fluid flow characteristics at the connection.

A seal assembly for a gas turbine engine employs a first seal forming an oil chamber around a bearing. The first seal is configured to maintain the oil chamber at a first pressure. A second seal forms a ventilating cavity around the oil chamber. The second seal is configured to maintain the ventilating cavity at a second pressure, the second pressure being less than the first pressure and less than an ambient pressure of a primary flow path in the engine. A pressure reducing device is coupled to the ventilating cavity. The pressure reducing device is configured to maintain the second pressure.

A galley cart system employs a housing with a door coupled to the housing, the door configured to be moved between a closed position and an open position. A vent plate in the housing communicates between a first compartment and a second compartment. A valve plate adjacent the vent plate is movable from a venting position when the door is in the closed position to a blocking position when the door is in the open position thereby preventing flow communication between the first and second compartment.

A system and method of sanitizing one or more structures within an enclosed space includes operatively coupling an ozone ventilation control unit to an ultraviolet (UV) light assembly, an ozone sensor, and an exhaust fan, using the ozone ventilation control unit to operate the UV light assembly to emit UV light into or onto structure(s) of the enclosed space during a cleaning cycle, receiving, by the ozone ventilation control unit, an ozone presence signal indicative of an amount of ozone within the enclosed space from an ozone sensor that detects the amount of ozone within the enclosed space, using the ozone ventilation control unit to selectively activate and deactivate the exhaust fan based on the amount of ozone within the enclosed space, and using the ozone ventilation control unit to selectively activate and deactivate the UV light assembly based on the amount of ozone within the enclosed space.

An aircraft air supply system may include a primary duct to supply a primary air flow to a flight deck of an aircraft. A nitrogen generating system may be configured for generating nitrogen enriched air and oxygen enriched air. A secondary duct may be provided for channeling the oxygen enriched air from the nitrogen generating system to the primary duct. The flow of the oxygen enriched air into the primary duct and to the flight deck may be controlled to reduce an effective altitude of the flight deck.

Aircraft air supply systems for reducing effective altitude of flight decks

A method and system are presented. The system comprises a plurality of baffles positioned to split an airflow from a door of an autoclave into a counter-rotating flow pattern.

An ultraviolet (UV) light sanitizing system is configured to sanitize a structure. The UV light sanitizing system includes a UV light assembly that is configured to emit UV light onto the structure, and a UV light emission control unit coupled to the UV light assembly. The UV light emission control unit is configured to control the UV light assembly to emit UV light onto the structure within at least a first UV band and a second UV band that differs from the first UV narrow band during a sanitizing cycle that sanitizes the structure. The UV light within the first and second UV bands is configured to kill at least one type of microbe.

A galley cart system employs a dry ice compartment and a refrigeration compartment in a galley cart in flow communication with the dry ice compartment. A ventilation system is in interruptible flow communication with at least the refrigeration compartment and is for receiving gas discharged from at least the refrigeration compartment.

A system for providing oxygen includes an oxygen generating device, configured to provide oxygenated air, a monitor of a condition of the air provided by the oxygen generating device, a backup oxygen supply, and an automatic switch. The automatic switch is configured to activate the backup oxygen supply and block air from the oxygen generating device when the monitor detects a failure of the condition of the air provided by the oxygen generating device. The system can be used for providing backup oxygen in an aircraft.

A system and methods for reducing pressure in an enclosed volume is disclosed. A first quantity of steam is inserted into a condensation chamber, and the first quantity of steam is substantially condensed in the condensation chamber. A first quantity of air is extracted from an enclosed volume into the condensation chamber.

System and methods for ground-based cabin/cargo pressurization/depressurization

An aircraft has a ventilation system that employs a plurality of nozzles positioned in a cavity between a sidewall of the aircraft cabin and a section of the aircraft fuselage. The nozzles receive a supply of ventilation air and direct jets of air from the nozzles, through the cavity and into the aircraft cabin. The jets of air produced by the nozzles create low-pressure areas in the cavity. At least one return air opening in the cabin sidewall communicates the low-pressure areas with the cabin interior, whereby the low pressure areas draw air from the cabin interior into the cavity where the drawn air is entrained with the jets of air produced by the nozzles. Devices inside the cavity remove suspended impurities from the air drawn into the cavity. In this manner, the ventilation system filters or sanitizes the air drawn through the system.
