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 ...
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 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 .
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]
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.
I’ve actually had numerous calls over 30 years of people’s dogs' choking, asking what to do." @Maura pointed out, "You probably just saved a lot of dogs’ lives. Thank you."
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.
