Team members’ innovative methods advance test operations for AEDC hypersonic propulsion facility

Lon Britt, left, and Robert Campbell, right, electricians, along with Adam Webb, an electrical engineer, look at a rectifier outside the Arnold Engineering Development Complex Aerodynamic and Propulsion Test Unit at Arnold Air Force Base, Tenn. Webb improved the logic used in the Programmable Logic Controllers on the units to handle uncommanded "runaways,” which allowed him to identify the part at fault.
