An open-jet wind tunnel operating within an anechoic chamber was developed for the purpose of the study of VSTOL noise mechanisms. An existing low-speed conventional hard walled wind tunnel was modified to operate as an open-jet tunnel an anechoic chamber was then constructed around the test section. The resulting aerodynamic and acoustic characteristics of the tunnel are discussed.
