An Overview of the Turbine Engine Measurement needs of the US Air Force and how the Propulsion Instrumentation Working Group is working to address those needs

William A. Stange, US Air Force,
Measurement Science and Systems Engineering (MSSE) Division Seminar

Abstract

This presentation will describe the technical difficulties and major shortcomings associated with making accurate measurements of various parameters in the hot section of turbine engines in the test cell environment. The status of a current contract effort to develop both the Nonintrusive Stress Measurement System (NSMS) (also known as Blade Tip Timing), as well as temperature measurement using Thermographic Phosphors will be reviewed, with emphasis on the area of Blade Tip Timing. As a major participant in the development of advanced measurement techniques for turbine engine test cell applications, this presentation will discuss the development and role of the Propulsion Instrumentation Working Group (PIWG) in addressing these and other engine measurement needs, as well as PIWG's efforts to establish collaborations with similar entities. This presentation will also discuss the on-going efforts of a new Standards Committee which is actively developing new Standards in five different areas of turbine engine measurement technology.
