WRIGHT BROTHERS WIND TUNNEL Since its opening in September 1938, the Wright Brothers Wind Tunnel has played a major role in the development of aerospace, civil engineering and architectural systems. In recent years, faculty research interests generated long-range studies of unsteady airfoil flow fields, jet engine inlet-vortex behavior, aeroelastic tests of unducted propeller fans, and panel methods for tunnel wall interaction effects. Industrial testing has ranged over auxiliary propulsion burner units, helicopter antenna pods, and in-flight trailing cables, as well as concepts for roofing attachments, a variety of stationary and vehicle mounted ground antenna configurations, the aeroelastic dynamics of airport control tower configurations for the Federal Aviation Authority, and the less anticipated live tests in Olympic ski gear, space suits for tare evaluations related to underwater simulations of weightless space activity, racing bicycles, subway station entrances, and Olympic rowing shells for oarlock system drag comparisons. In its nearly 80 years of operation, Wright Brothers Wind Tunnel work has been recorded in hundreds of theses and more than 1,000 technical reports.

In recent years there had been a growing problem with the mechanism controlling the tunnel fan’s blade pitch, which enables researchers to vary the air speed. During the spring of 2016, the blades and the original 77-year-old pitch gear and motor set were removed, refurbished, and reinstalled by a team comprising technical instructors Dave Robertson and Todd Billings, Gas Turbine Lab manager Jim Letendre, and Professor Mark Drela. The tunnel was returned to full operation in time for the Institute’s April 23 Open House, where it was a star attraction for thousands of visitors. WBWT faculty and staff include Professor Mark Drela and technical instructor David Robertson. Outreach activities are coordinated by communications director William Litant.
