Facilities and Equipment
Our state-of-the-art facilities allow us to stay at the forefront of research
Advanced Blast Simulators Facility
TNT Lab personnel have access to 1,500 sq. ft. of fully equipped laboratory space in the Center for Injury Biomechanics, which is located less than one mile from the main Virginia Tech Campus. Conventional shock tubes are quite limited in their ability to simulate blast waveforms. Our Advanced Blast Simulator facility has two state-of-the-art Advanced Blast Simulators (ABS) designed to intrinsically replicate all the key features of blast wave flow conditions, including the negative phase and secondary shock. The smaller ABS system (VT1) is 10ft long and has a 1 x 1 ft square testing section. VT1 is appropriate for testing specimens, such as small animals and material samples. The smaller system operates with compressed air or helium in the driver, which is seperated from the test section by a diaphragm. The diaphragm of choice is an acetate membrane available at different thicknesses, but other options are available. The peak static pressure of the shock front in the VT1 system can reach 30 psi (210 kPa) with a 2msec duration.
The large ABS system (VT4) is 45ft long and has a 4 x 4 ft testing section. VT4 is capable of accommodating large samples and it is available for cadaver, animal, materials, and physical surrogate testing. This system is driven by a gas detonation system. The peak static pressure generated within this system can reach up to 70 psi with a 4 msec duration.
Both VT ABS systems come equipped with multiple monitoring stations to track the development of the shock wave. In addition, observation windows provide quick access to specimens. Two separate data acquisition systems capable of sampling at 1MHz per channel are available (8 and 18 channel system). High-speed video cameras with lights are also available for use during testing.
Cell and Tissue Mechanics Lab
The TNT Cell Biomechanics laboratory is located in Kelly Hall on the campus of Virginia Tech. This facility houses student workstations and bench top wet laboratory research space. The lab contains important equipment for analyzing cell response to various injury mechanisms and design of novel treatment strategies such as high-speed video capabilities, biological laminar flow hoods, chemical fume hood, cell incubators, -20 and -80 freezers, analytical balances, Zeiss fluorescence/phase contrast microscopes, Real Time PCR machine, electrophoresis equipment, micro refrigerator centrifuge, bench top refrigerator centrifuge, Cyrostat tissue sectioning system, WES protein analysis station, and cell injury devices with oscilloscopes for data collection.
