TECHNOLOGIES
- High-Temperature Thin Film Multifunctional Sensor
- A microfabricated thin-film sensor to measure multiple parameters in high-temperature aerospace environments that is minimally intrusive to the system.
- Thin-Film Heat Flux Sensor (Improved Design)
- A new design for a thin film heat flux sensor utilizing a Wheatstone bridge is easier to fabricate, has a larger signal, and is more easily scalable than previous designs.
- Temperature Probe for Measuring up to 2400 °C
- This technology is for a probe that uses multiwavelengths to measure very high temperatures, from 1380 °C up to 2400 °C. The ability to withstand higher temperatures and oxidizing atmospheres translates into extended lifetimes even during operation in less severe conditions.
- Thin Film Air Mass Flow Sensor
- This technology uses thin film resistance temperature detectors in a bridge arrangement to measure air mass flow rate with minimal disruption of the flow.
- High-Temperature Thin-Film Strain Gauges
- The NASA Glenn Research Center has developed high-temperature thin-film strain gauges, which are miniature and deposited directly on the test articles. These sputter-deposited thin-film resistance strain gauges can provide minimally intrusive surface strain measurements in the temperature range from ambient up to 1100 °C.
- Thin Film Heat Flux Sensor
- The thin film heat flux sensors, being developed at NASA Glenn Research Center, are fabricated as a plug-type sensor on the surface of a ceramic material. They can also be fabricated directly on the surface of a part such as a turbine blade.
- Thin Film Thermocouples for Surface Temperature Measurement
- Thin film thermocouples have been developed for surface temperature measurement on several material systems for various aerospace applications.
- Beam Drag-Force Anemometer
- The drag-force anemometer is capable of measuring both static and dynamic velocity head and flow angle. In contrast to the hot-wire anemometer, the drag-force anemometer has an output that is proportional to the force exerted on the beam by the moving fluid.
- Dynamic Gas Temperature Measurement Probe
- The dynamic gas temperature measurement system developed by NASA can measure rapid temperature fluctuations to 1000 Hz in hot, high speed gas flows. It is capable of operating at the exit of a jet engine combustor, and can measure deviations of 600 K from the mean. The system requires less than a minute for data reduction on a PC.

NASA Fact
NASA GRC was built on the parking lot of the Cleveland Air Races in 1941. The wooden grandstand stood on the current site of the Hangar.
