Flow Field Surveys in a Transonic Compressor Rig

Abstract

As the Navy prepares to transition to F-35C Joint Strike Fighter the need to understand "pop stalls" caused by steam leakage in catapult systems is of concern. "Pop stalls" caused by steam ingestion through the aircraft engine result in a loss of power and possible engine stall. The F-35C is a single engine aircraft and therefore the probability of a "pop stall" resulting in the loss of the aircraft is increased. Investigation of this phenomenon is currently being examined at the Turbopropulsion Laboratory by means of a transonic compressor rotor. The present study utilizes both three and five-hole probes to survey the flow field upstream and downstream of the rotor to examine compressor stability. A new compressor performance map was defined and a validation of previous steam ingestion was performed.
