Detection and Quantification of Damage During Startup

Greg Beshori- Hoerbiger, Daniel Rem- Enbridge, Robert Goffin- AETC


The application of modern automation and combustion control technologies has greatly increased the reliability of engine operation when operating under load. Detonation and preignition along with unanticipated shutdowns have been reduced if not eliminated on modernized legacy engines. However starting and unloaded operation can result in substantial detonation and preignition resulting in pressure and temperatures which significantly exceed loaded operation. In addition, these combustion aberrations can trip an engine offline before it achieves stable loaded operation.
