Stall (fluid dynamics)
Videos
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value. The critical angle of attack is typically about 15°, but it may var

In aerobatics, the cobra maneuver, also called dynamic deceleration, among other names, is a dramatic and demanding maneuver in which an airplane flying at a moderate speed abruptly raises its nose mo

…engine thrust to replace lift, as well as alternative controls to replace the loss of effectiveness of the ailerons. Short-term stalls at 90–120° (e.g. Pugachev's cobra) are sometimes performed at airshows. The highest angle of attack in sustained flight so far demonstrated was 70° in the X-31 at the Dryden Flight…
