Optimization of the NPS Transonic Compressor Rig Downstream Pressure and Temperature Instrumentation

Abstract

In order to provide the fleet with the most beneficial research on military fan engines, the NPS Turbopropulsion Lab (TPL) required a modernization of its transonic compressor rig's (TCR) pressure and temperature instrumentation. An entirely new casing was designed and additively manufactured to provide a consistent datum for which new pressure and temperature rake probes could be designed and additively manufactured. This resulted in a more accurate and repeatable solution to map the internal characteristics of the rig. To optimize the instrumentation, a computational fluid dynamics (CFD) analysis was completed on the stator for the first time. Next, the CFD results guided the new design for the pressure and temperature probes by identifying the most effective measurement locations. In all, the TPL, and the Navy, will benefit for years to come as the TCR at NPS will provide more accurate and repeatable measurements on military fan engines.
