Abstract: A new experimental method for panoramic contactless determination of the laminar-turbulent transition position in a three-dimensional boundary layer is described. It is demonstrated that this method allows accurate determination of the transition region boundaries at both reduced and elevated degrees of free-stream turbulence.

Keywords: boundary layer, laminar-turbulent transition, panoramic methods of measurements, swept wing, crossflow vortices, hydrodynamic instability.
