High Tech with a Human Touch
Department of Mechanical and Aerospace Engineering
The Department of Mechanical and Aerospace Engineering at Florida Tech is among the top national programs engaged in cutting-edge advanced propulsion research for both rockets and air-breathing engines. Partnerships for funded research projects are in place with NASA-KSC, NASA-MSFC, U.S. Air Force, Space Florida, Masten Aerospace, Environmental Aerospace Corporation, and the Advanced Magnet Laboratory, as well as collaborations with other top national universities. A new partnership for research on micro-scale air-breathing engines is currently being established with Florida Turbine Technologies and a collaboration for gas turbine technologies studies for power generation has recently been put in place with Seimens.
Florida Tech is also the premier university for student designed and built rocket projects, with our pinnacle accomplishment being the first university to even have a student designed and built rocket successfully launched from Cape Canaveral Air Force Station. Currently there are several solid and hybrid rocket projects underway, including an attempt to launch a solid rocket to the edge of space (57 miles). Students are also participating in the deisgn of cryogenic liquid rocket propellant experiments that will be flown on the ZeroG aircraft in 2007.
A direct benefit of our propulsion research collaborations has been to help place our students in leading aerospace companies and laboratories including various NASA centers, Pratt & Whitney, General Electric, Boeing, the United Space Alliance, and Space Florida.

The NASA Launch Services Program's UCAT is used to analysze the flight performance of a series of specific launch vehicles. A series of non-propietary, generic launch vehicles have been simulated ranging from a relatively simple single-stage, solid propellant sounding rocket to a more complex two-stage liquid rocket. The generic models span a broad range of rockets classes and are slected to highlight various features of the UCAT modeling tool. New features and capabilities, including a propulsion module, have been added to the UCAT modeling suite.
