A UAH aerospace engineering undergraduate student's idea for a new, more efficient way to package rocket engines has won him and two UAH professors a recent patent. Sean Entrekin, now a UAH graduate with a master's degree in aerospace engineering, is an experimental flight test engineer at Redstone Testing Center. He joined with Dr. James Blackmon, a research professor at the UAH Propulsion Research Center, and Dr. Brian Landrum, an associate professor of aerospace engineering, in the patent award.
