Career Experience: Compressor Engineer
Introduction:

Over the next eleven years I performed a wide variety of tasks in Pratt's Compressor Component Design and Engineering Group, including:
- performance modeling and data analysis of axial flow compressors using 3-Dimensional (Streamline) analysis
- aerodynamic test support of full-size and scaled compressor test rigs
- hardware inspection of experimental blades and vanes
- aerodynamic design of axial compressor blades & vanes, and fan exit guide vanes (FEGV)
- data reduction and analysis of aerothermodynamic (pressure-temperature-flow)data
- providing aerodynamic and data reduction/analysis test support for Pratt & Whitney's first use of Laser Doppler Velocimetry in both a multistage compressor and a counter-rotating high-speed swept fan.
- writing, editing, layout, and desktop publishing of an interdepartmental newsletter focusing on quality for the Engineering Group
- the occasional "G-Job"
- ...and even reviewing a US Patent on Controlled Diffusion Airfoils.
Some Work Examples...
Here are a few examples from the records I've still retained from this portion of my career:At right is an example of a Data Reduction Flowchart proposed for reducing and comparing Laser Velocimetry (LV, or velocimetric) data to traditional aerothermodynamic (Pressure / Temperature / Flow) data. The comparisons allowed analysts to use independently-measured velocity data to improve their 2d and 3D models for loss, turning, and turbulence.

As a member of Pratt's first "Group Quality Team" during 1990-91 I edited and produced a newsletter for the Engineering Department's "Component Design & Technology Group". This monthly newsletter, highlighting quality activies of the various Component sub-groups, was distributed to the entire Group's 400-plus employees. It was produced on a Mac SE using "Ready, Set, Go!" v.3 (Click here for the full newsletter (pdf, 549kb)) |

When Pratt & Whitney announced a poster contest for their quality improvement initiative ("Q+"), I sarcastically asked my collegues during a lunch break "How tough could it be to design a poster?", and quickly sketched one out on a napkin. Apparently, it wasn't tough at all: Not only did my entry win, but it was so popular that upon my return to Pratt in 2001 - after beng laid off in 1991 - I still saw these posters proudly hanging throughout the manufacturing floor. |
