Editing Delta wing (section)

====High-speed supersonic waveriding====
At high supersonic speeds, the shock cone from the leading edge root angles further back to lie along the wing surface behind the leading edge. It is no longer possible for the sideways flow to occur and the aerodynamic characteristics change considerably.<ref name="mason10-1" /> It is in this flight regime that the [[waverider]] design, as used on the [[North American XB-70 Valkyrie]], becomes practicable. Here, a shock body beneath the wing creates an attached shockwave and the high pressure associated with the wave provides significant lift without increasing drag.
