Abstract:
The present invention provides a system and method for cooling the bleed air supply in an on-board inert gas generation system. The gas generation system cools the bleed air using a turbocompressor in conjunction with heat exchangers. Exhaust from a regenerative heat exchanger providing air to the turbocompressor is ported to a ram air outlet using a flow-restriction/ejector unit.

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).
