Supersonic laminar flow control studies in the SUPERTRAC project

• The global objective of the SUPERTRAC project is to explore the possibilities to delay laminar-turbulent transition on supersonic aircraft wings. The following techniques are investigated: micron-sized roughness elements, anti-contamination devices, suction and shape optimization. This paper provides an overview of the project and describes in more detail the numerical investigations performed during the first year in order to design two wind tunnel models. These models will be used to assess the capabilities of the first three techniques listed above.
