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...

thinner wing gave it a considerably higher critical Mach number (about 0.89). Drag divergence Mach number L. J. Clancy (1975) Aerodynamics, Pitman Publishing...

by shock waves formed when flying at or above the aircraft's drag divergence Mach number. Shock stall may cause control problem during speed transition...

Supercritical airfoils feature four main benefits: they have a higher drag-divergence Mach number, they develop shock waves farther aft than traditional airfoils...

rest. The wing is a supercritical design with a 0.87 to 0.88 drag divergence Mach number depending upon lift coefficient. It is based on the G650's wing...

sweep. The wing root glove reportedly increased the drag divergence Mach number of the wing by Mach 0.02. Though initially fitted with turbojet engines...

The Mach number (M or Ma), often only Mach, (/mɑːk/; German: [max]) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity...

Flight tests revealed that the aircraft exhibited a higher drag divergence Mach number than predicted by wind tunnel data. The maximum lift coefficient...

approach Mach 1.0. At such speeds, shock waves form in the air passing over the wings, drastically increasing the drag due to drag divergence, causing Mach buffet...

the wing. There is a following point called the drag divergence mach number where the effect of the drag from the shocks becomes noticeable. This is normally...

speed of sound, often stated as starting at speeds of Mach 5 and above. The precise Mach number at which a craft can be said to be flying at hypersonic...

or efficiency, the required area ratio increases with flight Mach number. If the divergence is too short giving too small an exit area the exhaust will...

reduced trim drag and reduced wave drag, while using the strakes for trim in situations where the center of gravity is off provides less trim drag than relying...

incompressible fluid dynamics, the Mach number of the flow is evaluated. As a rough guide, compressible effects can be ignored at Mach numbers below approximately...

consider the flow over a transonic airfoil. The airfoil is operating at a Mach number of 0.8 and an angle of attack of 1.25 degrees. We assume that the shape...

\mathbf {u} } is the flow velocity, ∇ ⋅ {\textstyle \nabla \cdot \,} is the divergence, p {\textstyle p} is the pressure, t {\textstyle t} is time, τ {\textstyle...

consequence of the Gauss divergence theorem and the Kelvin–Stokes theorem. According to the (purely mathematical) Gauss divergence theorem, the electric...

the vehicle increases speed to the Critical Mach number. It is the sudden and dramatic rise of wave drag that leads to the concept of a sound barrier...
