Abstract: In some examples, a computing device is configured to monitor an air quality of a vehicle cabin by at least receiving, from a plurality of remote sensors distributed throughout the cabin, signals indicative of one or more air quality parameters for air in the cabin. Based on the received signals, the computing device can determine if values for the one or more air quality parameters are indicative of an air quality event and generate an output in response to such a determination. The output may include, for example, an audio or visual indication of the air quality event or a signal to control another system of the aircraft to take action to remedy the air quality event.

Abstract: A system configured to compress air to be used by a power generation system includes a first compressor stage configured to be driven by exhaust air from the power generation system and a second compressor stage configured to be driven by electrical power generated by the power generation system.

Abstract: A temperature sensor arrangement (100, 300) includes a sensor cavity (150), a temperature sensing element (330) being positioned along a center line (140, 340) of the sensor cavity (150) and generating a signal indicating temperature of air flowing thereto, and a generally cylindrical outer casing (105, 305) surrounding the sensor cavity (150). In one embodiment, the outer casing (105) includes a pattern of flow passages (110) for allowing air flow to the temperature sensing element (330) in the sensor cavity (150), the flow passages (110) being angled such that there is no direct line of air flow from an exterior of the outer casing (105) to the sensing element (330). In another embodiment, the flow passages (310) are arranged in an offset pattern relative to a center line (340) of the housing cavity (150), such that there is no direct line of air flow from an exterior of the outer casing (305) to the sensing element (330).
