The CLA facility was established in 1984 as a state funded “Center of Excellence” to provide outstanding capabilities in research, education, and technology transfer relating to laser applications. The CLA occupies buildings 8184 and 8189 and consists of over 29,000 ft2 of lab and office space. The laboratories contain advanced laser system, optics, materials processing and analytical systems. The labs also include a class clean room nano-fabrication facility and a chemistry lab.
- Chemistry Science Laboratory

- High Pressure Air
- High pressure air flow capabilities include eighteen 3,000 psig air storage tanks that are valved into a blow-down air supply system. This can provide up to 6,200 lbm flow capacity at 10 to 200 lbm/s. Lower flow rates can be controlled with an alternate regulator, and system recharge is provided at 500 lbm/h.
- Low Pressure Air
- Low pressure, high volume flow is provided at 6 lbm/sec up to 150 psi by regulating the 3000 psig high pressure supply through a Dresser/Grove 311B Powreactor 1.5” regulator (Cv = 26). This air is piped to the PRF facility underground 1080 ft through 4” pipe that provides geothermal temperature stability.
- Heated Low Pressure Air
- The UTSI Propulsion Research Facility has the capability of supplying heated air with flow rates up to 6 lbm/sec and pressures up to 150 psi. This can be directed though a 0.5 um Balston coalescing filter and a 274KW HETC electric air heater. Examples of capabilities are heated air at 2.0 lbm/sec at 500°F or 1.46 lbm/sec at 650°F. The air comes from the high pressure storage facility with at least 6,200 lbm of usable air that can be recharged at a rate of 0.75lbm/sec or the low pressure compressors.
A water channel laboratory is available for fluid flow modeling studies. The facility includes an Aerolab water channel that has a 15” x 20” x 60” test section with three transparent sides. The water speed is infinitely variable from 0 to 3 ft/sec. Up to 6 different colored or florescent dyes may be injected for flow visualization. Laser light sheets to aid visualization can be created using 405nm or 513 nm lasers. A custom 2 axis force balance is also available for lift and drag studies. Water velocity is monitored using a Sierra Instruments, Innova-Sonic Model 205 ultrasonic flow meter.
- Low Speed Wind Tunnel Facility
- Contains a subsonic, single pass, ambient air wind tunnel. Precise air speeds of 0 – 250 fps can be controlled through its 14 inch high, 20 inch wide, 3 foot long test section. The tunnel is also equipped with a 29” by 9.5” moving floor to simulate a roadbed for vehicle aerodynamic studies. The flow is monitored and controlled with a National Instruments LabVIEW DAQ and control system.
- HORIZON Center
- The High-Speed Original Research and Innovation Zone (HORIZON) was founded in the fall of 2014 when John Schmisseur joined the faculty at UTSI. His goal was to conduct foundational research in aerothermodynamics and the science of ground testing through both his research on the numerical modeling of complex flows and shock waves, and the experimental capabilities of the university. He is building a center with the goal of national leadership in aerospace and defense research.
- TALon (Tennessee Aerothermal Laboratory)
