For more than\u202f100\u202fyears, wind tunnels at NASA\u2019s Langley Research Center in Hampton, Virginia, have helped shape the future of flight.\u202f\u00a0<\/p>\n

Now, two of\u202fNASA\u2019s\u202flongest-serving facilities \u2014 the 12-Foot Low-Speed Tunnel\u202fand the 20-Foot Vertical Spin Tunnel\u202f\u2014\u202fwill pass\u202fthe torch to\u202fthe Flight Dynamics Research Facility (FDRF),\u202fthe first major NASA wind tunnel built in more than 40 years.\u202f\u00a0<\/p>\n

\u201cThe FDRF has a combination of features found in no other single facility in the world,\u201d said Mike\u00a0Fremaux,\u00a0retired\u00a0chief engineer for the Intelligent Flight Systems division at NASA Langley. \u201cIt\u2019s a high-performance vertical wind tunnel with a large test section capable of conducting all manner of tests to assess the dynamics of flight vehicles.\u201d \u00a0<\/p>\n

When the FDRF opens later this year, it will provide enhanced versions of the capabilities offered by the two legacy facilities. The FDRF\u2019s test\u00a0section will allow researchers to drop models into a rising vertical airflow. This will offer researchers the ability to conduct spin tests of aircraft and free-flight tests of vehicles designed to re-enter Earth\u2019s atmosphere from space. \u00a0<\/p>\n

The FDRF will play an integral role in conducting research that supports NASA\u2019s aeronautics, science, and space exploration missions. Like many NASA facilities, the FDRF\u2019s story is rooted in a history of\u00a0innovation.<\/p>\n

12-Foot Low-Speed Tunnel<\/strong>\u202f\u00a0<\/strong><\/h1>\n

When the 12-Foot Low-Speed Tunnel began operations in 1939, aviation looked very different than it does today.<\/p>\n

It was built for NASA\u2019s predecessor agency, the National Advisory Committee for Aeronautics (NACA) to study the controllability of airplanes using free flight. Aircraft models flew unsupported in the wind it generated, instead of being mounted to\u00a0supports. Multiple operators used rudimentary remote controls to operate the models in the tunnel. \u00a0<\/p>\n

The facility that housed the tunnel boasted a unique design: a 60-foot diameter sphere. The configuration allowed the tunnel to move and adapt to the flight paths of free flying models. \u201cPilots\u201d could use hydraulic actuators, pivoting the tunnel\u2019s test section to match the models\u2019 movements. The spherical design made it easy for air from the facility\u2019s fan to recirculate through the tunnel, regardless of the pitch angle of the test section. \u00a0<\/p>\n

In 1958, NASA moved the free-flight tests to another Langley\u00a0tunnel<\/a>.\u00a0The agency deactivated the 12-Foot\u2019s hydraulic actuators, fixing its test section into a horizontal position, and began using it for more conventional testing, looking at how aerodynamic force affected the stability and control of strut-mounted models.<\/p>\n

The 12-Foot supported major projects throughout its 86 years of service, from the transition from\u00a0bi-planes to monoplanes between two world wars, through the development of supersonic aircraft. Revolutionary designs saw testing in the 12-Foot, from the forward-swept-wing X-29<\/a> and the X-31<\/a> Enhanced\u00a0Fighter\u00a0Maneuverability Demonstrator, to the more recent X-59<\/a> quiet\u00a0supersonic research aircraft, and the aeroshell for NASA\u2019s Dragonfly<\/a>, a unique rotorcraft designed to explore Titan, Saturn\u2019s largest moon. \u00a0<\/p>\n

20-Foot\u202fVertical Spin Tunnel<\/strong>\u202f\u00a0<\/strong><\/h1>\n

While the 12-Foot tested new ideas for aircraft and components, the\u00a020-Foot\u00a0Vertical Spin Tunnel played a critical role in aviation safety. \u00a0<\/p>\n

Opened in 1941, the Vertical Spin Tunnel was designed to study aircraft stall and spin characteristics. Its aim was to prevent deadly accidents in which an aircraft enters an uncontrolled spin. The vertical design allowed models to fall into the rising airflow, simulating how aircraft behave during a spin. Researchers hand-launched models into the tunnel\u2019s vertically rising airstream to evaluate those characteristics. \u00a0<\/p>\n

The tunnel quickly became one of the most important spin-testing facilities in the world. Research supported commercial aviation, parachute design systems, NASA space missions, and the development of nearly every U.S. military aircraft designed since World War II. \u00a0<\/p>\n

Models from many of those tests will be on display in the FDRF\u2019s lobby, a testament to the Vertical Spin Tunnel\u2019s rich history. \u00a0<\/p>\n

\u201cIt is great to showcase the legacy of work that started in the NACA days and will continue going forward for decades to come,\u201d\u00a0Fremaux\u00a0said.<\/p>\n

New\u00a0era of\u00a0flight\u00a0research<\/strong><\/strong><\/h1>\n

The\u00a0FDRF will continue NASA\u2019s commitment to world-class facilities and the unique expertise of\u00a0the agency\u2019s\u00a0workforce. \u00a0<\/p>\n

\u201cThat\u2019s what kept those other facilities going,\u201d\u00a0Fremaux\u00a0said. \u201cNot just the buildings, the fans, and the motors, but also the expertise associated with those facilities. You can\u2019t have one without the other.\u201d \u00a0<\/p>\n

The FDRF will build not only on the history of the 12-Foot\u00a0tunnel\u00a0and the Vertical Spin Tunnel,\u00a0but\u00a0on\u00a0their equipment, including\u00a0many of their major test rigs, instrumentation, and data systems, were repurposed for use in the FDRF, reducing costs and development time. \u00a0<\/p>\n

As NASA returns astronauts to the Moon through the Artemis\u00a0program,\u00a0the FDRF will play a vital role in testing the technologies for entry, descent, and landing that will ensure a safe return to Earth. Research within the FDRF\u00a0also\u00a0will\u00a0support science missions to planets and moons with atmospheres, such as Venus and Saturn\u2019s moon, Titan. The 25,000-square-foot facility will play a major role in experimental research for NASA\u2019s development of X-planes, autonomous flight vehicles, and drones. \u00a0<\/p>\n

\u201cFor me, seeing FDRF come alive and being prepared to begin supporting important agency missions, after 30 years of working on the concept behind the scenes with formal and informal teams of motivated, innovative coworkers, is the most rewarding capstone I could have in my career,\u201d Fremaux said. \u00a0<\/p>\n

Just as the 12-Foot Low-Speed Tunnel and the\u00a020-Foot\u00a0Vertical Spin Tunnel supported decades of aerospace innovation, the FDRF is ready to shape the future of flight.<\/p>\n
