Shadowgraphs show a winged model launched into atmospheric air from a gun.
The bow wave is marginally attached at this slightly supersonic speed. In the plan view above, the wings are lifting, as shown by trailing vortices from the tips. In the side view below, the herringbone pattern is produced by pressure pulses from grooves in the wing that trip the boundary layer to make it turbulent over the rear half.
