Transonic — is an aeronautics term referring to a range of velocities just below and above the speed of sound (about mach 0.8–1.2). It is defined as the range of speeds between the critical mach number, when some parts of the airflow over an aircraft become… … Wikipedia
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
Mach number — (mathrm{Ma} or M) (generally pronEng|ˈmɑːk, sometimes IPA|/ˈmɑːx/ or IPA|/ˈmæk/) is the speed of an object moving through air, or any fluid substance, divided by the speed of sound as it is in that substance. It is commonly used to represent an… … Wikipedia
Subsonic and transonic wind tunnel — ubsonic tunnelLow speed wind tunnels are used for operations at very low mach number, with speeds in the test section up to 400 km/h ( 100 m/s, M = 0.3). They are of open return type ( losses. Open wind tunnelThe working principle is based on the … 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
detachment Mach number — The free stream Mach number above which there is only a small movement of the bow shock wave with an increase in speed. It indicates the upper limit of a transonic region … Aviation dictionary
