Team members’ innovative methods advance test operations for AEDC hypersonic propulsion facility
Electricians Lon Britt, left, and Robert Campbell, right, along with electrical engineer Adam Webb look at a rectifier, like one that was responsible for an un-commanded "runaway" condition, outside the AEDC Aerodynamic and Propulsion Test Unit at Arnold Air Force base. Webb improved the logic used in the Programmable Logic Controllers on the units to handle un-commanded "runaways,” which allowed him to identify the part at fault.
