Mach wave Mach wave In fluid dynamics, a Mach wave is a pressure wave traveling with the speed of sound caused by a slight change of pressure added to a compressible flow. These weak waves can combine in supersonic flow to become a shock wave if sufficient Mach waves are present at any location. Such a shock wave is called a Mach stem or Mach front. Thus, it is possible to have shockless compression or expansion in a supersonic flow by having the production of Mach waves sufficiently spaced ("cf." isentropic compression in supersonic flows). A Mach wave is the weak limit
Mach Five kind of terrain (firm, icy, unsteady ground, and significant slopes). Control G = Homing robot (As in the original) When pressed, the Mach Five releases a remote control robot bird capable of transmitting footage back to the Mach Five from wherever it is. This function wasn't used in the film. In the 1959 movie "On the Beach" Dr Julian Osborne (played by Fred Astaire) races in a white number 5 Ferrari while wearing a white helmet and goggles—eerily similar to Speed Racer in the Mach Five. In the animated 2008 series, which takes place about 40 years after the events
