This is a short description of my background re. the 3 changes I just submitted for the Pratt & Whitney Canada PT 6 engine design. I retired in 1999 from a 9 year career as Director, Component Engineering, Pratt & Whitney Canada plus  1 1/2 years as Director, Advanced Engineering. In the 9 year span I was responsible for the analytical design of the PW 500 series engines, the PW307, 308, the 150 and preliminary design of the 600. Preceding that I was the manager responsible for the PW100 series turbomachinery aerodynamics and the same for the PW 305 engine. Preceding that I was responsible for the aerodynamic research of compressors dating back to 1964. In that capacity I carried out the basic research of the Vrana pipe diffuser and shared an additional patent (with the mechanical designer, S. Jarosz) for the diffusing duct carrying air from the radial plane drillings to the annular duct surrounding the reverse flow combustor. I published 9 technical papers on the aerodynamics of centrifugal compressors under the Gas Turbine Div. of the ASME, AIAA, CASI and the Von Karman Institute of AGARD (the scientific arm of NATO).I also lectured at the Von Karman Inst. and MIT in the US.
