The University of Connecticut
The University of Connecticut is a state-supported institution with a total enrollment of about 25,000 students. The School of Engineering , located on the main campus at Storrs , Connecticut , has a total enrollment of about 1700 students, with over 500 graduate students.
Connecticut is home to many companies that develop high technology components and systems, including Pratt & Whitney, Hamilton Standard, Sikorsky, United Technologies Research Center , Textron-Lycoming, General Dynamics-Electric Boat. Over the years, the University has developed strong partnerships with local industry, and this is especially true of the relationships with Pratt & Whitney and the United Technologies Research Center involving gas turbine engine research activities, including aerodynamics, heat transfer, structures, life-time prediction systems, materials/manufacturing processing.
Faculty
There are about 12 faculty members in the mechanical engineering and metallurgy department involved in various aspects of power generation and gas turbine engine research. Of note, Dr. Lee S. Langston of the mechanical engineering department is former chairman of the International Gas Turbine Institute.
