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"
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.
The Kulbit drastically decreases the aircraft's speed and could theoretically be used to cause a pursuing aircraft to overshoot its target. The maneuver is closely related to the famous "Pugachev's Cobra" maneuver, but the Kulbit completes the loop that the Cobra almost immediately cuts off.
The first T-10K flew in August 1987 flown by the famous Soviet test pilot Viktor Pugachev (who first demonstrated the Cobra maneuver using an Su-27 in 1989), performing test takeoffs from a land-based ski-jump carrier deck on the Black Sea coast at Saky in the Ukrainian SSR. The aircraft was lost in an accident in 1988.
Equipped with a digital fly-by-wire system, the Su-30 can perform some very advanced maneuvers, including the Pugachev's Cobra and the tailslide. These manoeuvers quickly decelerate the aircraft, causing a pursuing fighter to overshoot, as well as breaking a Doppler radar-lock , as the relative speed of the aircraft drops below the threshold ...
