Summary
24-Inch High Speed Tunnel (24-Inch HST): Construction of the foundation for the tunnel. Construction was authorized in 1933 and was built using funds from the Federal Public Works Administration (PWA). The initial cost was $12,600. Eastman Jacobs, John Stack, Ira Abbott, W.F. Lindsey and Kenneth Ward participated in the design of this new tunnel which could investigate airfoils and fuselages at twice the Reynolds numbers of the 11-inch HST. L9648 shows the completed foundation for the outer housing for the 15-Foot Spin Tunnel. Charles Zimmerman was given the assignment to design and build a larger spin tunnel that would supplant the 5-foot Vertical Wind Tunnel. Authorization to build the tunnel using funds from the Federal Public Works Administration (PWA) came in June 1933. Construction started in late winter 1934 and the tunnel was operational in April 1935. The initial construction costs were $64,000
