Each month in “Slice of History” we feature a historical photo from the JPL Archives. See more historical photos and explore the JPL Archives at https://beacon.jpl.nasa.gov/.
In December 1974, this photo was taken of the Low Speed Wind Tunnel. NASA’s Jet Propulsion Laboratory had 21-, 20-, and 12-inch wind tunnels that were very well documented, but an April 1967 report about JPL wind tunnels does not mention this facility and very little is known about it. It appears in 1961 drawings of building 80, which was next door to the main wind tunnel building but it may have been relocated years later. The March 1968 JPL telephone book indicates that there was a Low Density Wind Tunnel in building 183, room 601, belonging to the Fluid Physics Section. The section number prefix for this image indicates that it was photographed for the Research and Advanced Concepts Section, but the photo was taken at the request of Paul Massier of the Structures and Dynamics Section. Massier was seen in the June “Slice of History” blog taken in the anechoic chamber.
