Brace yourselves as we explore the University of Texas at Arlington Aerodynamics Research Center. This isn’t just another building it is a hub of innovation. The Aerodynamics Research Building has propelled the university to the forefront of aerospace research.
Established in 1986 this center emerged from humble beginnings. It started as an aircraft maintenance and fabrication facility back in the 1930s. The Aerodynamics Research Building’s current form took shape. It allowed for a significant expansion of equipment. The ARC now features low-speed transonic supersonic arc jet and hypersonic wind tunnels. It stands as a unique facility at the university level.
Let’s step back to 1975. UTA began developing a shock tube for magnetohydrodynamic power generation research. Simultaneously the Aerospace Engineering Department needed a high-speed wind tunnel. An arc heater was acquired but sat unused due to funding shortages.
A turning point arrived in 1976. Two professors visited AEDC and NASA’s Marshall Space Flight Center. They sought inspiration for a smaller Ludwieg tube wind tunnel at UTA. Serendipitously AEDC had just decommissioned its Ludwieg tube. This tube was a prototype for the Air Force’s National Transonic Facility Development Program. UTA jokingly requested the tube. The AEDC project manager took it seriously. The Ludwieg tube was declared government surplus and donated to UTA. It arrived in Arlington on three flatbed cars.
The Ludwieg tube attracted lucrative grants. A temporary facility was built on the first floor of a new engineering building. It was located directly beneath the office of the Dean of Engineering. The Dean quickly made it a permanent building. He knew how loud the Ludwieg tube was. More wind tunnels and equipment were added.
In 1985 NASA Ames Research Center donated a large compressor to UTA. This five-stage Clark compressor was rated at 3000 psi and 2000 cfm. It was driven by a 1250 hp motor. Moving the compressor and associated equipment cost nearly $500000. The Aerodynamics Research Building was built around the compressor in 1986. Supersonic and hypersonic facilities were later added.
The low-speed wind tunnel is a closed-circuit continuous flow tunnel. It has a 100 hp variable frequency drive. The test section measures 0.6 by 0.9 meters. It is capable of flow velocities up to 50 m/s.
The high Reynolds number transonic Ludwieg tube wind tunnel is an impulse facility. It has a porous wall test section that measures 19.5 by 23.2 cm. Its run time is about 120 ms. The Mach number range is 0.5 to 1.2.
The supersonic wind tunnel is a blowdown-type tunnel. It is equipped with a variable Mach number nozzle. The achievable Mach number range is 1.5 to 4.0.
The hypersonic shock tunnel is another impulse facility. Its run time is 0.5 to 5.0 ms. It can test at Mach numbers from 5 to 16.
The arc-heated wind tunnel uses a 2 MW DC electric arc heater. It produces supersonic streams of extremely hot gas. The gas is heated to temperatures ranging from 3000 to 5000 K.
Today the Aerodynamics Research Building continues to push boundaries. Current research focuses on high-speed aerodynamics. Shock/boundary layer interaction and detonation engineering are also studied. The center also uses Computational Fluid Dynamics. Experimental test results validate CFD models and vice versa. The Aerodynamics Research Building stands as a testament to innovation. It is a hub where groundbreaking discoveries take flight.
