In aerobatics, the cobra maneuver (or just the cobra), also called dynamic deceleration, [1] among other names (see § Etymology), is a dramatic and demanding maneuver in which an airplane flying at a moderate speed abruptly raises its nose momentarily to a vertical and slightly past vertical attitude, causing an extremely high angle of attack and making the plane into a full-body air brake ...
Pugachev's Cobra maneuver is one of the tests for supermaneuverability, here performed by an Su-27. Supermaneuverability is the capability of fighter aircraft to execute tactical maneuvers that are not possible with purely aerodynamic techniques. Such maneuvers can involve controlled side-slipping or angles of attack beyond maximum lift. [1]
Pugachev's Cobra; the nose of the aircraft is pulled up suddenly. The aircraft pitches up to 90–120° angle of attack. The nose then falls back to the horizontal, and the aircraft accelerates away in the original direction ; Kulbit; post-stall maneuver similar to Pugachev's Cobra, but going to 360° pitch angle, flying a "loop"
In modern aerobatics, this maneuver, if executed pre-stall with a non-zero turning radius at the top of the climb, is known as a wingover. If the rudder turn is executed right at the initiation of the stall, the resulting yaw occurs around a point within the aircraft's wingspan and the maneuver is known as a stall turn or hammerhead.
Do you ever feel really horny after working out? Well, there’s a reason for that. You release hormones while working out, including adrenaline and dopamine a.k.a. the so-called "feel-good" chemical.
The Russian Su-27 Flanker can, in theory, lock an adversary with IRST and perform a cobra maneuver in which it suddenly pitches upwards but continues laterally, gaining 90 degrees or higher of AoA, and launches a heat-seeking missile. The missile is able to engage the enemy aircraft after it has overshot the Flanker, often without the adversary ...
The Heimlich maneuver is a first-aid method recommended by most health organizations, which uses abdominal thrusts to dislodge an obstruction from a person’s windpipe. Boy, 8, Saves Choking ...
