Internal flow investigations on the Rolls Royce Allison T-63 engine

A collaborative investigation has been initiated by the Royal Military College of Canada (RMC) and Standard Aero Limited (SAL) of Winnipeg. The objectives of the project are to study compressor instabilities, to investigate the internal aerodynamic characteristics of the major engine stages and their influences on downstream components, and to quantify the temperature profile at the exit of a combustion chamber. The program will initially explore rotating compressor stall in the axial stage of a Rolls Royce Allison A250 gas turbine. Three follow-on research thrusts will explore the centrifugal stage on the same rig, while an existing combustion chamber test rig will be used to explore the effects of inlet disturbances on the combustion chamber. Finally, compressor discharge ducts will be surveyed and modelled to determine influences between the two major components. SAL is a major global overhauler and engineering developer of the A250 gas turbine engine and the insight gained will be applied to improving their role as an engineering service provider. HQP specifically post-graduate students will be drawn from SAL employees; other students will be attracted from conventional sources.
