Abstract
A temperature sensing assembly configured for a fire detection system for an aircraft, wherein the temperature sensing assembly includes: a plate of material having a thermal conductivity at least 200 W/(m·K), and a plurality of thermocouples arranged on the plate. A controller is configured to receive the temperatures measured by the thermocouples and determine if one or more of the measured temperatures complies with at least one predetermined criterion.

A temperature sensing assembly configured for a fire detection system for an aircraft, wherein the temperature sensing assembly includes:
- a plate of material having a thermal conductivity of at least 200 W/(m·K), and
- a plurality of thermocouples arranged on the plate,
- wherein the temperature sensing assembly is included in the fire detection system on the aircraft.
An aircraft comprising:
- an engine configured to combust fuel to generate power for the aircraft;
- a fuselage with a rear section housing the auxiliary power unit;
- a skin of the rear section of the fuselage at least partially encloses the auxiliary power unit;
- a plate of material having a thermal conductivity of at least 200 W/(m·K), wherein the plate is a portion of the skin or positioned on an inside surface of the skin proximate engine;
- thermocouples arranged at various locations on the plate such that the thermocouples form a pattern covering at least an upper portion of the engine, and
- a computer controller configured to:
- receive temperature data indicating temperatures at various locations on the plate from the thermocouples;
- determine from the temperature data the temperatures at the various locations on the plate;
- determine if one or more of the temperatures meet at least one predetermined criterion, and issue an alert if the one or more of the temperatures meet the at least one predetermined criterion.
