The design, development, and performance of equipment suitable for use by educational institutions for student training and basic compressible-flow research are described. The equipment consists of an induction tunnel having a 4- by 16-inch test section and capable of operating at Mach numbers ranging from about 0.4 to 1.4 and a blowdown tunnel having a 4- by 4-inch test section for supersonic Mach numbers up to about 4.0.
