Career Experience: Compressor Engineer

Introduction:

As a Gas Turbine Compressor Engineer in Pratt & Whitney's Compressor Component Design and Engineering Group I performed a wide variety of tasks 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.
My tasks also included creating dedicated computer programs to handle, reduce, and analyze data, defining & writing procedures, developing & providing training, vetting colleagues, and proposing and implementing databases to catalog all of the test data and analysis.

Some (Unredacted) 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. Note that company-sensitive information has been redacted.

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

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.
