| Facility History: | Facility History LSAF was derived from the original large (anechoic) test chamber or LTC commissioned in 1974 primarily built for jet engine nozzle testing. Major renovation completed in 1989 was addition of .25 mach free jet capability. In 1996 a mach boost insert was added to the LSAF contraction. In 2002 a new control room and automated model control system was added. |
