AIAA R-146-2020

AIAA R-146-2020: The AIAA Ground Test Technical Committee (GTTC) Dual Flow Reference Nozzle Working Group has developed recommended practices and aerodynamic definitions for two types of reference nozzles intended to verify thrust rigs measuring subscale exhaust nozzle system performance. Two different reference nozzles are defined: Dual Separate Flow Reference (DSFR) and Dual Mixed Flow Reference (DMFR). The recommended specifications focus on defining reference nozzle aerodynamic loft lines and features including flow conditioning, instrumentation, operational procedures, and data reduction procedures.
