Pugachev Cobra SU-37
The Pugachev Cobra is a fighter aircraft maneuver. It is a demonstration of the pitch control authority, high angle of attack (AOA) stability and engine/inlet compatibility at high angles of attack of the aircraft. The maneuver allows for very quick turns which can make an attack fail or put the pilot in a position to execute an attack. It is an example of air combat manoeuvering (ACM). Many Western experts on ACM believe this maneuver has absolutely no value in actual air combat; nonetheless, the Pugachev Cobra is known to be one of the most aesthetic, dramatic, demanding and beautiful maneuvers performed at air shows worldwide. The maneuver is so named after the Sukhoi OKB (design bureau) test pilot Viktor Pugachev, who first performed the maneuver.
