A sensor assembly includes a housing and a tube. The housing has a first leading edge portion which is capable of being located in a compressor/fan inlet flow path and which includes an interior wall section. The tube has a proximal portion including an air inlet which is adapted to receive a compressor bleed air flow and a distal portion which is located in the housing and which includes at least one air outlet hole. The hole is spaced apart from the interior wall section and is aligned to direct at least some compressor bleed air flow to impinge against the interior wall section. The housing includes an opening which receives air from the flow path when the housing is located in the flow path, wherein the opening is adapted for fluid communication with a sensor, and wherein the sensor measures at least one of air temperature and air pressure.

The invention claimed is: 1. A sensor assembly comprising: a) a housing having a first leading edge portion which is disposable in a compressor/fan inlet flow path and which includes an interior wall section; b) a tube having a proximal portion including an air inlet which is adapted to receive a compressor bleed air flow and having a distal portion disposed in the housing and including at least one air outlet hole which is spaced apart from the interior wall section and which is aligned to direct at least some of the compressor bleed air flow to impinge against the interior wall section, wherein the housing includes an opening which receives air from the compressor/fan inlet flow path when the housing is disposed in the compressor/fan inlet flow path, wherein the opening is adapted for fluid communication with a sensor, and wherein the sensor measures at least one of air temperature and air pressure. 2. The sensor assembly of claim 1, wherein the sensor measures air temperature and is disposed in the housing. 3. The sensor assembly of claim 2, wherein the at-least-one air outlet hole includes a plurality of air outlet holes. 4. The sensor assembly of claim 3, wherein the plurality of air outlet holes are substantially linearly aligned. 5. The sensor assembly of claim 2, wherein the housing includes at least one spent-impingement-air exhaust hole which is in fluid communication with at least some of the compressor bleed air flow which impinged against the interior wall section. 6. The sensor assembly of claim 2, also including a tubular sheath surrounding, and spaced apart from, the proximal portion of the tube. 7. The sensor assembly of claim 6, wherein the housing, the tube, and the tubular sheath consist essentially of steel. 8. The sensor assembly of claim 2, wherein the compressor bleed air flow is an aircraft gas-turbine-engine compressor bleed air flow. 9. The sensor assembly of claim 8, wherein the aircraft gas-turbine-engine compressor bleed air flow is an aircraft gas-turbine-engine high-pressure-compressor bleed air flow. 10. The sensor assembly of claim 2, wherein the sensor is in fluid communication with aspirated air from the compressor/fan inlet flow path. 11. The sensor assembly of claim 2, wherein the housing includes a trailing edge which is disposable in the compressor/fan inlet flow path, and wherein the sensor is disposed between the tube and the trailing edge. 12. The sensor assembly of claim 11, wherein the housing includes at least one air outlet passageway leading from the sensor to the trailing edge. 13. The sensor assembly of claim 12, wherein the housing includes a second leading edge portion, wherein, when the first leading edge portion is disposed in the compressor/fan inlet flow path, the second leading edge portion extends a greater distance into the compressor/fan inlet flow path than does the first leading edge portion and the second leading edge portion is disposed downstream of the first leading edge portion, wherein the second leading edge portion includes an air scoop, and wherein the sensor is in aspirated fluid communication with air entering the air scoop. 14. The sensor assembly of claim 13, wherein the housing includes at least one spent-impingement-air exhaust hole which is in fluid communication with at least some of the compressor bleed air flow which impinged against the interior wall section of the first leading edge portion of the housing, and wherein, when the first leading edge portion is disposed in the compressor/fan inlet flow path, the air scoop is disposed a greater distance into the compressor/fan inlet flow path than is the at-least-one spent-impingement-air exhaust hole. 15. The sensor assembly of claim 14, wherein the housing includes first and second sides extending from the first leading edge portion to the trailing edge, wherein the at-least-one spent-impingement air exhaust hole includes a first air exhaust hole disposed on the first side and a second air exhaust hole disposed on the second side, and wherein the first and second air exhaust holes are disposed upstream from the sensor. 16. The sensor assembly of claim 2, wherein the housing is attachable to an aircraft-gas-turbine-engine structure. 17. A sensor assembly comprising: a) a housing having a first leading edge portion which is disposed in a compressor/fan inlet flow path and which includes an interior wall section; b) a tube having a proximal portion including an air inlet receiving a compressor bleed air flow and having a distal portion disposed in the housing and including at least one air outlet hole which is spaced apart from the interior wall section and which is aligned to direct at least some of the compressor bleed air flow to impinge against the interior wall section, wherein the housing includes an opening which receives air from the compressor/fan inlet flow path, wherein the opening is adapted for fluid communication with a sensor, and wherein the sensor measures at least one of air temperature and air pressure. 18. The sensor assembly of claim 17, wherein the housing is attached to an aircraft-gas-turbine-engine structure, and wherein the housing is one of a monolithic housing and a contiguous multi part housing. 19. A sensor assembly comprising: a) a housing having a first leading edge portion which is disposable in a compressor/fan inlet flow path and which includes an interior wall section; b) a tube having a proximal portion including an air inlet which is adapted to receive a compressor bleed air flow and having a distal portion disposed in the housing and including at least one air outlet hole which is spaced apart from the interior wall section and which is aligned to direct at least some of the compressor bleed air flow to impinge against the interior wall section; and c) a sensor which measures air temperature, which is disposed within the housing and which is in fluid communication with air from the compressor/fan inlet flow path when the first leading edge portion is disposed in the compressor flow path, wherein the housing includes at least one spent-impingement-air exhaust hole which is in fluid communication with at least some of the compressor bleed air flow which impinged against the interior wall section, also including a tubular sheath surrounding, and spaced apart from, the proximal portion of the tube, wherein the sensor is in fluid communication with aspirated air from the compressor/fan inlet flow path, wherein the housing includes a trailing edge which is disposable in the compressor/fan inlet flow path, and wherein the sensor is disposed between the tube and the trailing edge, and wherein the housing includes at least one air outlet passageway leading from the sensor to the trailing edge. 20.
