Abstract

Sensor assemblies, comprising one or more sensors for use in high-temperature environments such as an aircraft wing, include a thermally conductive retaining member in thermal communication with either the sensor or the environment surrounding the sensor. A housing assembly placed proximate to, and in thermal communication with, the retaining member defines a fluid passageway. During operation, fluid circulates through the housing to enhance the transfer of heat away from the sensor. Such heat transfer facilitates maintaining a sensor environment within the tolerance range of the sensor, thereby facilitating monitoring of the pressure fluctuation (or other sensor parameter) during operation of the aircraft.

Claims

1. A sensor assembly for monitoring at least one condition proximate a surface of an aircraft, said sensor assembly comprising:

a plurality of sensors;

at least one retaining member having at least one of said plurality of sensors retained therein, said at least one retaining member having an upper surface cooperatively configured with said surface of said aircraft to lie proximate said surface of said aircraft and further having a securing portion extending from said retaining member'"'"'s surface through at least a portion of said surface of said aircraft; and

at least one fluid chamber cooperatively arranged proximate said at least one retaining member to establish thermal communication between said plurality of sensors in said at least one retaining member and a fluid within said at least one fluid chamber to control the temperature environment of said plurality of sensors.

2. The sensor assembly of claim 1, wherein said at least one retaining member has a generally cylindrical body portion, and wherein said at least one fluid chamber is defined by a housing, and wherein each said body portion of said retaining member extends through a portion of said housing of an associated fluid chamber.

3. The sensor assembly of claim 1, wherein said plurality of sensors comprises at least one acoustic sensor.

4. A sensor assembly for monitoring at least one condition proximate a surface of an aircraft, comprising:

a retaining member, said retaining member having an upper surface configured to lie proximate the surface of said aircraft, and having a securing portion configured to extend through at least a portion of the surface of said aircraft, said retaining member comprising a bore therein;

a sensor, said sensor retained at least partially within said bore of said retaining member;

a fluid housing, said fluid housing configured to extend around said securing portion of said retaining member and to establish thermal communication therebetween, said fluid housing comprising a fluid passage; and

a securing member adapted to secure said retaining member to said aircraft surface and to secure said fluid housing proximate said retaining member.

5. The sensor assembly of claim 4, wherein said retaining member is formed at least partially of metal, and wherein said fluid housing is formed at least partially of metal.

6. The sensor assembly of claim 4, wherein said sensor comprises an acoustic sensor.

7. The sensor assembly of claim 4, further comprising a volume of fluid passed through said housing.
