INSTRUMENTATION AND MEASUREMENT.

Abstract

NASA has instrumentation and measurement programs covering virtually all areas of aerospace technology. Program emphasis is on increased capability, performance, and economy. Three main topics from NASA's instrumentation program are discussed here: the custody transfer of gases; instruments for the testing and monitoring of machinery - specifically large industrial gas turbines; and data handling and control. The instrumentation and measurement techniques described were developed for and are being used in turbomachinery research and development. It is clear, however, that they all have a much more general applicability. Refs.
