Wind-Tunnel Testing

Airfoils Incorporated offers experimental verification of its airfoil designs and high-lift systems using appropriate wind-tunnel facilities.

Facilities

Investigations are conducted primarily in the following facilities, in order of increasing Reynolds number capability:

• The Pennsylvania State University low-speed, low-turbulence wind tunnel, University Park, Pennsylvania, USA
• The low-turbulence wind tunnel of the Delft University of Technology Low Speed Laboratory, Delft, The Netherlands
• The NASA Langley Low-Turbulence Pressure Tunnel, Hampton, Virginia, USA

Other facilities may be utilized as required.

Service

This service normally consists of:

1. The selection of and contracting and coordination with the wind-tunnel facility
2. The development of the test plan, including Reynolds and Mach numbers and angle-of-attack schedules
3. The specification of the wind-tunnel model, including chord, dimensional coordinates, orifice size and locations, and drawings
4. The fabrication of the wind-tunnel model, including coordination, inspection, and verification of coordinates and orifice locations
5. Conducting the investigation
6. Analyzing and reporting the results.
