Viktor Georgiyevich Pugachev (Russian: Ви́ктор Гео́ргиевич Пугачёв) (born 8 August 1948 in Taganrog, RSFSR) is [1] a retired Russian Air Force officer and a former Soviet test pilot who was the first to demonstrate the so-called Pugachev's Cobra manoeuvre to the general public in 1989, flying an Su-27.
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 unconventional wing design also had the side effect of making it the first known aircraft to be capable of and perform the Cobra maneuver. [ 8 ] [ 9 ] [ 10 ] It was also one of the first Western-European-built aircraft to exceed Mach 2 in level flight, [ 11 ] reaching it on January 14, 1960.
However, as supermaneuverability itself is defined, the ability of an aircraft to perform high alpha maneuvers that are impossible for most aircraft is evidence of the aircraft's supermaneuverability. Such maneuvers include Pugachev's Cobra and the Herbst maneuver (also known as the "J-turn").
The maneuver is used to equalize pressure in the middle ear. Today, the maneuver is also performed by scuba divers, free divers and by passengers on aircraft as they descend. [1] [2] [3] The trapped air inside the mouth and nasal cavities is compressed by the movement of the tongue or larynx while doing Frenzel maneuver.

Heimlich was enjoying a steak dinner at the Dupree House senior living facility, when he noticed the 87-year-old Patty Ris choking on her hamburger.
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 .
