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 ...
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]
Karl Friedrich Louis Dobermann (/ ˈ d oʊ b ər m ə n /; German pronunciation: [ˈdoːbɐman]; 2 January 1834 – 9 June 1894) was the first breeder of the Dobermann.He started the creation of this dog breed in the town of Apolda, in the Grand Duchy of Saxe-Weimar-Eisenach around 1890, following the Franco-Prussian War.
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.
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.
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."
Split-S gif animation. The split S is an Aerobatic maneuver and an air combat maneuver mostly used to disengage from combat. To execute a split S, the pilot half-rolls his aircraft inverted and executes a descending half-loop, resulting in level flight in the opposite direction at a lower altitude.
