LEWIS RESEARCH CENTER 21000 Brookpark Road Cleveland, OH 44135 NASA's Lewis Research Center occupies 360 acres of land adjacent to the Cleveland Hopkins International Airport, some 20 miles southwest of Cleveland, Ohio. More than 100 buildings comprise the center which is staffed by about 2,800 government employees and some 1,400 on-site contractors. Additional facilities, currently being brought back on line, are located at Plum Brook Station, about 3 miles south of Sandusky, Ohio. The center was established in 1941 by the National Advisory Committee for Aeronautics (NACA). Named for George W. Lewis, NACA's Director of Research from 1924 to 1947, the center developed an international reputation for its research on jet propulsion systems. Lewis is NASA's lead center for research, technology and development in aircraft propulsion, space propulsion, space power and satellite communications. The center has been advancing propulsion technology to enable aircraft to fly faster, farther and higher and also focused its research on fuel economy, noise abatement, reliability and reduced pollution. The center pioneered efforts in the use of high energy fuels for both air breathing and space propulsion. Projects demonstrated the practicality of liquid hydrogen as a fuel, leading to its use in the Apollo and the Space Shuttle programs as prime examples. Lewis has responsibility for developing the largest space power system ever designed to provide the electrical power necessary to accommodate the life support systems and research experiments to be conducted aboard the Space Station. In addition, the center will support the station in other major areas such as auxiliary propulsion systems and communications. Lewis is the home of the Microgravity Materials Science Laboratory, a unique facility to qualify potential space experiments. Other facilities include a zero-gravity drop tower, wind tunnels, space tanks, chemical rocket thrust stands and chambers for testing jet engine efficiency and noise. A major computer complex supports both the center's scientific and administrative activities. Individual computer work stations are dispersed throughout the center with network connections among them. Dr. John M. Klineberg is Center Director.
