The Mechanical and Aerospace Engineering department at Princeton University has one of the top aerospace propulsion research labs in the world. Engineers who were educated there have been designing new aircraft engines at Pratt & Whitney, United Technologies and General Electric for many years. They use combustion models developed at Princeton which describe the chemistry that occurs when jet fuel burns, including the chemistry of emissions. Feeding into work the Princeton lab is doing with the U.S. Air Force, the project that NetJets is sponsoring will apply what is being learned in related research on bio-fuels and alternative jet fuels to business jets.This project will identify the most promising ways to develop and commercialise green aviation fuel technology. The research team pursuing this work includes aerospace engineers Fred Dryer and Yijunang Ju, joined by Robert Williams and Eric Larson at the Princeton Environmental Institute. NetJets is the first and only commercial backer of this project.
