The breathable waterproof sheet includes a waterproof air-permeable layer formed of a film having elasticity, an adhesive layer having one surface adhered to one surface of the waterproof air-permeable layer, and a support layer having a plurality of air-permeable holes formed therein and having one surface adhered to the other surface of the adhesive layer.

A sensor includes an airfoil body, a heater element, and a temperature probe. The airfoil body defines a sensor axis, an insulating cavity, and extends between a leading edge and a trailing edge of the airfoil body. The heater element extends axially within the airfoil body and is positioned between the leading edge and the trailing edge of the airfoil body. The temperature probe extends axially within the airfoil body, is positioned between the heater element and the trailing edge of the airfoil body, and is separated from the heater element by the insulating cavity to limit thermal communication between the temperature probe and the heater element. Gas turbine engines, methods of making sensors, and methods of thermally separating temperature probes and heater elements in sensors are also described.
