Dynamic stall is a non-linear unsteady aerodynamic effect that occurs when aerofoils rapidly change the angle of attack. The rapid change can cause a strong vortex to be shed from the leading edge of the aerofoil, and travel backwards above the wing. The vortex, containing high velocity airflows, briefly increases the lift produced by the wing. As soon as it passes behind the trailing edge, however, the lift reduces dramatically, and the wing is in normal stall. 5, record 1, English, - aerodynamic%20stall

The computer method consists of applying the three full Navier-Stokes equations of fluid mechanics(...) over a pattern of points on a theoretical airframe before any hardware exists. Plotted over a sufficiently large number of points around an aerodynamic shape, these equations can predict lift, drag and heating. Some unsteady [air] flow patterns, such as the 3, 000 Hz shock wave buzz round the inlet spike of a missile at Mach 3, have been successfully plotted. 1, record 2, English, - inlet%20spike

La méthode sur ordinateur consiste à appliquer les trois équations complètes de Navier-Stokes sur la mécanique des fluides (...) à un certain nombre de points d'une cellule théorique. Si on les applique à un nombre suffisant de points d'une surface aérodynamique, elles permettent de connaître la portance, la traînée et l'échauffement cinétique. Cette méthode a permis de déterminer correctement certains types d'écoulements instables, tels que le "bourdonnement" de 3000 Hz dû aux ondes de choc, qui se produit à Mach 3 autour du cône d'entrée d'air d'un missile. 1, record 2, French, - c%C3%B4ne%20d%27entr%C3%A9e%20d%27air
