To begin a study related to the High Speed Theory, it is necessary to know that the aircraft are classified according to the being: subsonic, transonic, hypersonic or supersonic. Directly related to there are still the so-called pressure waves, which are concentric waves printed in the air by any object that produces sound or which travels in the Earth's atmosphere, these propagate at a speed of 340 m/s or 1224 km/h at the mean sea level. The Aircraft in flight produces these waves, which are formed around them and move 360º around it. In this study, the nose of the aircraft and the area of greater curvature in the extrados of the wing as expansion waveformers, in order to study the wave of Shock, Mach number and critical Mach number.
