New approaches to traditional sensor fabrication and methodology have been developed allowing sensors to be deposited directly onto conformal components. The Company’s Direct Write MesoPlasma™ process enables structural health sensing capabilities for gas turbine engines and aerospace structures operating in harsh environments. Thermocouple and strain sensors are embedded within protective coatings and allow for both wire connections and wireless interrogation.
Recent activity has focused on increasing sensor durability at high temperatures. Thermocouple sensors were deposited onto coupons and engine components and subjected to a number of thermal exposure tests using oxy-acetylene burner rigs, lasers, and high pressure combustion test rigs. In addition, advances in high temperature strain measurement capability will be reported for both static and dynamic strain applications.
