Description
The 9- by 15-Foot Low Speed Wind Tunnel (9x15), housed in the return leg of the 8- by 6-Foot Supersonic Wind Tunnel, provides a unique facility for testing large-scale hardware in a continuous subsonic air stream. The test section is 9 ft. high and 15 ft. wide by 28 ft. long and provides airspeeds from 0 to 175 mph. The facility is used to evaluate aerodynamic performance and acoustic characteristics of nozzles, inlets, and propellers and to test short and vertical take off and landing aircraft systems.

Airspeed :	0 - 175 mph
Test Section:	9-ft high by 15-ft wide by 28-ft long
Reynolds Number :	0 - 1.4 x 10⁶/ft
Dynamic Pressure:	0 - 72 psf
Temperature:	ambient - 550°R
