  • Critical Mach number — Transonic flow patterns on an aircraft wing showing the effects at critical mach. In aerodynamics, the critical Mach number (Mcr) of an aircraft is the lowest Mach number at which the airflow over any part of the aircraft reaches the speed of… …   Wikipedia

  • Drag divergence Mach number — The drag divergence Mach number (not to be confused with critical Mach number) is the Mach number at which the aerodynamic drag on an airfoil or airframe begins to increase rapidly as the Mach number continues to increase[1]. This increase can… …   Wikipedia

  • drag divergence Mach number — The Mach number at which there is a sudden rise in wing drag as a result of the formation of shock waves. Buffet may take place and control difficulty may occur at this Mach number …   Aviation dictionary

  • Mach tuck — is an aerodynamic effect, whereby the nose of an aircraft tends to pitch downwards as the airflow around the wing reaches supersonic speeds. Note that the aircraft is subsonic, and traveling significantly below Mach 1.0, when it experiences this… …   Wikipedia
