Paul Trame, BSE’65, MSE’67., Senior Development Engineer
After being laid off from Williams International (builder of the Cruise Missile, and small Jet Engines) when we lost several follow-on programs with Russia’s collapse in 1991, I found a job at Ford Motor Company’s Advanced V-Engine group.One of the things they were working on was better fuel atomization for cleaner emissions at start-up. I was able to use my knowledge of supersonic nozzles to design a small (.050 inch throat) nozzle that provided 20 to 40 micron particles—much better than the 200 micron spray from the fuel injectors.
