In a method of this type, it is provided to use a "cold", internally cooled heat shield to allow the heated and/or evaporated or gasified coolant stream to flow out via nozzles in the heat shield essentially against the flight direction. As a result, the ejected coolant stream forms a "cold" recirculation zone, which is located in front of the heat shield and deflects the approaching hot stream from the vehicle surface. This measure produces a change in the extreme flow drag.
