High-temperature Turbine Alternator

The APS Turbine Alternator^† is a high-temperature, axial flow design for use in measurement-while-drilling (MWD) and logging-while-drilling (LWD) systems. This development, partially supported by Sandia Laboratories, provides reliable, ongoing power at temperatures of up to 200°C, taking the place of expensive, short-lived disposable batteries. The turbine is configurable to match the required flow rates for typical BHA/ hole size combinations.
