1. A jet engine having a core that sources a first flow of fluid and a component that sources a second flow of fluid, wherein the first flow of fluid has a higher temperature than the second flow of fluid, the jet engine further comprising:
at least one flow aperture formed by a first passageway to receive at least a portion of the second flow of fluid, wherein the first passageway is comprised of at least one material that deflects as a function of temperature such that a flow of the second flow of fluid through the at least one flow aperture is thereby desirably modulated;
wherein the at least one flow aperture further comprises a thermal barrier coating disposed to thermally isolate the first passageway such that deflection of the at least one material that deflects as a function of temperature that is adjacent to the first flow of fluid accurately tracks a temperature of the first flow of fluid.
