A40283 — Moffett Field CA: National Advisory Committee for Aeronautics. Very Good. 0. Hardcover. B&W Illustrations; This group of sixteen 8" x 10" black and white photographs from the NACA Ames Aeronautical Laboratory all have the NACA logo and photograph identification inside the photo and an identifier notation at the bottom edge of the white outer border. The photos themselves mostly cover the the use of Schlieren photography at supersonic or subsonic speeds or the wind tunnels in which the photography was produced. The photographs are all in Very Good condition. Two of the photographs have ink stamped designation from NACA which has been crossed out with blue pen. Unfortunately the photos are undated but can be positively dated between 1944 and 1958. "On 9 August 1939 as World War II began Congress authorized the construction of a second National Advisory Committee for Aeronautics NACA laboratory for urgent research in aircraft structures. Ground was broken for the laboratory at Moffett Field California in December 1939 and operations began in early 1941. NACA named the facility "Ames Aeronautical Laboratory" in 1944 in honor of Dr. Joseph S. Ames leading aerodynamicist and former president of Johns Hopkins University. Wind tunnels are central to Ames' history. Several wind tunnels were opened in the 1940s to test and refine aircraft guided missiles satellites and reentry bodies. Of particular note are three tunnels later designated key national resources. The 40 x 80-foot wind tunnel opened in June 1944 to conduct aircraft development work. The 12-foot subsonic wind tunnel opened in July 1946. The Unitary Plan Wind Tunnel enabled Ames to conduct new research; almost all NASA manned space vehicles including the Space Shuttle were tested in the Unitary." from Wikipedia .
