4 Οκτ 2024 · A high-speed buffet, also known as Mach buffet, occurs when an aircraft approaches or exceeds its critical Mach number. This phenomenon is caused by the airflow over the wings becoming turbulent, leading to a loss of control effectiveness and stability.
Named after Ernst Mach, a 19th century Austrian physicist, Mach is the ratio of an aircraft’s true speed compared to the local speed of sound at a given time or place.

Associated with “drag rise” are buffet (known as Mach buffet), trim, and stability changes and a decrease in control force effectiveness. The loss of lift due to airflow separation results in a loss of downwash and a change in the position of the center pressure on the wing.
8 Ιαν 2016 · Buffet is a kind of vibration caused by aerodynamic excitation, usually associated with separated (or turbulent) airflow. As the aircraft approaches stall, the airflow over the wing becomes turbulent and if it flows across the horizontal stabilizer, buffeting may occur.
11 Απρ 2017 · Turbulent flow develops behind the wing, causing a buffet called mach buffet. You can also experience mach tuck after you pass the critical mach number. The supersonic air flowing past the leading edge of the wing generates far more lift than the subsonic (and often stalled) air aft of the shock wave.
