Abstract: Current engine condition monitoring (ECM) systems for jet engines include the analysis of on-wing gas path data using steady-state performance models. Such data, which are also referred to as performance snapshots, usually ...

Abstract: This paper addresses the unsteady formation of secondary flow structures inside a turbine rotor passage. The first stage of a twostage, lowpressure turbine is investigated at a Reynolds Number of 75,000. The design represents ...
