Abstract: A thermal ice protection system including a spray tube for spraying engine bleed air on an interior surface of an aircraft wing leading edge. The engine bleed air impinges simultaneously at multiple locations on the interior surface heats the aircraft leading edge so as to inhibit the formation of ice on the aircraft leading edge at the predetermined ice susceptible areas. The spray tube is particularly intended to be used to heat a wing slat leading edge skin/surface without using a nose beam or other internal structure to direct the flow of the engine bleed air.

Abstract: Disclosed is a temperature sensor for measuring a temperature of a reference material. The temperature sensor includes a thermocouple, spring, and spring housing. The thermocouple is configured to measure the temperature of the reference material. The spring is operably coupled to the thermocouple and the spring housing is configured to accommodate the spring and thermocouple within the spring housing. Additionally, the spring housing is configured to attach to the reference material and the spring applies a force on the thermocouple in a direction towards the reference material.
