Abstract:
A carbon dioxide conversion system for an environment includes a first gas-liquid contactor-separator downstream of the environment; an electrochemical conversion cell downstream of the first gas-liquid contactor-separator; and a cleaned ionic liquid storage intermediate the first gas-liquid contactor-separator and the electrochemical conversion cell.
Abstract:
An Environmental Control System includes sensors, an air purification subsystem, and a controller in communication with the sensors and air purification subsystem. The sensors detect contaminants in outside air supplied through engine and APU bleeds or other air sources including ground supplies and electric compressors, contaminants in recirculated air, particulates in outside air, carbon dioxide in recirculated air, temperature in an environment, and pressure in an environment. These sensed parameters are compared against thresholds. Based on the comparisons, changes to the outside air and/or recirculated air are made.
Abstract:
An Environmental Control System includes a sensor, an air purification subsystem, and a controller in communication with the sensor and air purification subsystem. The sensor detects a contaminant in the air and generates a contaminant signal. The controller compares the contaminant signal to a predicted sensory response threshold. When the contaminant signal reaches the predicted sensory response threshold, the controller commands the air purification subsystem to alter a condition in the air.

Abstract:
An example liquid mirror includes a first ionic liquid and a second ionic liquid. The first and second ionic liquids are immiscible with each other. The liquid mirror also includes a plurality of reflective particles configured to self-assemble at an interface between the first and second ionic liquids.
Abstract:
A thermal process system includes a retort assembly, a heating assembly, and a vessel housing. The retort assembly includes a retort chamber and is configured to substantially form a containment boundary to contain one or more gases in the retort chamber during a thermal process. The heating assembly includes one or more heating elements and is configured to heat the retort chamber. The vessel housing is positioned around the retort chamber and the one or more heating elements and configured to form a pressure boundary to maintain a pressure within the retort chamber and reduce a pressure across the retort chamber.
Abstract:
An environmental control system includes an air conditioning subsystem and a contaminant removal subsystem downstream of the environment to be conditioned. The contaminant removal subsystem includes: a first gas-liquid contactor-separator; a second gas-liquid contactor-separator; and a dehumidifier disposed either upstream of the first gas-liquid contactor-separator or downstream of the second gas-liquid contactor-separator.
Abstract:
A contaminant removal system for removing a contaminant from an environment includes a gas separator, a scrubber-separator downstream of the gas separator, and a stripper-separator downstream of the scrubber-separator. The gas separator is configured to receive a cabin air stream from the environment and concentrate the contaminant from the cabin air stream to produce a concentrated cabin air stream. The cabin air stream includes the contaminant, and the concentrated cabin air stream has a higher concentration of the contaminant than the cabin air stream. The scrubber-separator is configured to absorb the contaminant from the concentrated cabin air stream into a liquid sorbent and discharge a clean air stream to the environment. The stripper-separator is configured to desorb the contaminant from the liquid sorbent into a contaminant stream.
Abstract:
A system and method for sanitizing a surface within an aircraft includes emitting UV radiation from a UV radiation source toward the surface, and emitting visible light from a visible light source toward the surface. A UV sensor senses an intensity of the UV radiation reflected by a reflector that is disposed on a least a portion of the surface and a visible light senses an intensity of the visible light reflected by the reflector. A processor processes the UV intensity signal and the visible light intensity signal to determine the intensity of the UV radiation on the surface and a UV dose to the surface.
