Determination of Engine Recovery After a Rollback, Engine Performance Deterioration and Health Monitoring Using Minimal Instrumentation During NASA Icing Testing in PSL3

摘要

This paper discusses methods and considerations used for determining when an ALF502-R5A turbofan engine has recovered from an icing induced rollback event, engine deterioration and health trending while testing in the Propulsion Systems Laboratory (PSL) at NASA Glenn Research Center in Cleveland, OH. It is based on successes and lessons learned from the first research engine, S/N LF01 in Q1 of 2013 and the second research engine, LF11 at NASA Glenn in Q4 of 2015. This paper will be given as part of a coordinated series by Honeywell, NASA, Ice Crystal Consortium and the Canadian National Research Council (NRC), all to be presented at the Washington, D.C. symposium in June, 2016.
