mach speed
These speeds are concurrently below, at, and above the speed of sound, ranging from Mach 0.8 to 1.2 (273-409 m/s; 980-1,470 km/h; 609-914 ..., What is Mach? The Mach number describes the aircraft's speed compared with the speed of sound in air, with Mach 1 equating to the speed of ...,跳到 High-speed flow around objects - The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1. ,Supersonic travel is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea ... ,跳到 Classification of Mach regimes - Classification of Mach regimes[edit]. Although "subsonic" and "supersonic" usually refer to speeds below and above ... ,A typical convention used in aeronautics is to define transonic flight as speeds in the range of Mach 0.72 to 1.0 (965–1,235 km/h (600–767 mph) at sea level). ,Before the introduction of Mach meters, accurate measurements of supersonic speeds could only be made externally, normally using ground-based instruments. , For the lowest subsonic conditions, compressibility can be ignored. As the speed of the object approaches the speed of sound, the flight Mach ...
