A mechanical engineering professor from The University of Texas at El Paso will help enhance the sustainability of structures moving at hypersonic speeds through a $130,000 grant from the Air Force Research Laboratory (AFRL). alvin M. Stewart, Ph.D., associate professor of mechanical engineering in UTEP’s College of Engineering, is the principal investigator of the award from the AFRL. The grant will be used to conduct experimental and computational research on materials for hypersonic cruise vehicles (HVCs).
