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 ...
The ability of these aircraft to perform this maneuver is based in inherent instability like that of the F-16; the MiG-29 and Su-27 families of jets are designed for desirable post-stall behavior. Thus, when performing a maneuver like Pugachev's Cobra the aircraft will stall as the nose pitches up and the airflow over the wing becomes separated ...
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"
The alternate name, "Frolov's Chakra", refers to Russian test pilot Yevgeni Frolov, the pilot who first carried out the maneuver, while "chakra" is a yogic term, meaning "vortex" or "whirlpool". The Kulbit drastically decreases the aircraft's speed and could theoretically be used to cause a pursuing aircraft to overshoot its target.
3D Aerobatics or 3D flying is a form of flying using flying aircraft to perform specific aerial maneuvers. They are usually performed when the aircraft had been intentionally placed in a stalled position for purposes of entertainment or display.
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 ...
Due to this, J 35 pilots were trained to prevent super stalls, and this training led to the development of the cobra maneuver. The cobra is performed by entering into a controlled super stall state, gaining high alpha and then quickly negating the angle of attack to counter the stall. [ 8 ]
Exit the maneuver as the above method. This maneuver calls for a specific type of aircraft. Since the motion involves rapid downward pitch, a low-wing aircraft with high thrustline is desirable, as it naturally creates the downward pitch moment. Also, the aircraft should readily snap on command.
