Dynamics and Control Branch Staff in the 10- by 10-Foot Supersonic Wind Tunnel

Members of the Wind Tunnel and Flight Division’s Dynamics and Control Branch examine a supersonic inlet in the 10- by 10-Foot Supersonic Wind Tunnel at the National Aeronautics and Space Administration (NASA) Lewis Research Center. From left to right: Kirby Hiller, Miles Dustin, Gary Cole, and George Neiner. The 30-person Dynamics and Control Branch analyzed the dynamic behavior and control of advanced engine systems. They sought to better understand propulsion system dynamics and control the system during flow disturbances. The group conducted both analytical and experimental research in variety of test facilities including the 10- by 10, 8- by 6-Foot Supersonic Wind Tunnel, and the Propulsion Systems Laboratory. The Dynamics and Control Branch, led by Daniel Drain, consisted of three sections: System Dynamics, Propulsion Systems Control, and Simulation. Digital computer controls for propulsion systems was one of the branch’s emphases at the time. Engine control systems determine the fuel required to produce the 171 specific levels of desired thrust. The thrust must be available despite the presence of turbulence or other abnormal flight conditions. NASA researchers next sought to integrate all engine components through a single digital computer.
