Low Speed Wind Tunnel


The Lockheed Martin Aeronautics Low Speed Wind Tunnel (LSWT) is a conventional single return, closed test section ground test facility located in Marietta, Georgia. Since its establishment in 1967, the LSWT has supported over 2500 tests, logging nearly 50,000 hours of air-on test time, and 125,000 hours of complete test support for government, commercial, and in-house customers.

The circuit features a pair of tandem subsonic test sections, ideal for both aerospace and automotive applications. Featured testing capabilities include aerodynamic force & moment measurement, surface and duct pressure capture, engine inlet performance and flow simulations, and control surface loads measurement. Tunnel walls have been acoustically treated to minimize ambient noise in the primary test section, making this facility a desirable asset for wind noise characterization as well.

The LSWT provides complete protection of customer proprietary data and for the security of government-classified information. Personnel access can be controlled in accordance with customer requirements.


The LSWT staff has decades of experience in wind tunnel testing, and are the perfect resource to help customize test plans from start to finish:

  • Model design using CAD and FEA tools
  • Instrumentation selection and calibration
  • Data reduction programming and transmission
  • Real-time data review and analysis
  • Model hardware on-site fabrication and repair
