EDM and Rokide Flame Spray on Turbine Engine Blades
Wire electrical discharge machining (EDM), an industrial cutting process, is performed on lead wire holes and egress slots on power-generating turbine engine blades for installation of thermocouples and high-temperature strain gauges. A Rokide™ flame spray, one of the best methods of attaching strain gauges in extreme environments, is used to guarantee sensor survivability. Static and dynamic sensors for gas turbine components measure stress, strain, and vibration. HITEC’s extreme environment instrumentation expertise allows for accurate performance in a maximum temperature of 2012°F.
Strain Gauge Instrumentation for Full-Scale Static Load Measurement
Strain gauges are used on wind turbine blades for full-scale static load measurement, design validation, and fatigue testing for cycle loading and certification requirements. Strain gauge instrumentation services can be provided on location or here at our facility.
Rokide Application for Strain Gauges on Turbine Engine Fuel Spray Nozzles
120 Ohm free-filament strain gauges are installed using a high-temperature Rokide application on the turbine engine fuel spray nozzle. The strain gauges are installed onto the inlet fitting assembly prior to the braze cycle to provide for dynamic strain data and testing. After the assembly braze cycle, strain gauges are installed on the flange and outer stem at operating temperatures of 1350°F.
