Pugachev's Cobra

From Wikipedia, the free encyclopedia

The Pugachev's Cobra (or Pugachev Cobra) is an aircraft cobra 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 (i.e. supermaneuverability^[1]). 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 maneuvering (ACM), specifically poststall maneuvering^[2]. The Pugachev's Cobra is considered to be one of the most dramatic and demanding 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 officially in 1989 at the Paris Le Bourget air show.

[edit] Description

The maneuver consists of the pilot pulling the aircraft to a 90°–120° angle of attack, then back down to zero. In a properly performed Pugachev's Cobra, the plane maintains a straight and level flight throughout the maneuver.

The vertical form of this maneuver is called a Cobra, named after the snake that behaves in a similar manner. Performing the maneuver on the horizontal plane results in the aircraft effectively stopping while the enemy overshoots, leaving the aircraft in a position for a straightforward missile attack on the enemy aircraft.^[3]

[edit] Aircraft known to be able to make the Cobra maneuver

Aircraft known to be able to make the Cobra maneuver are:

• The Su-27 'Flanker' family (from horizontal flight);
• The MiG-29 'Fulcrum' (from a 30 degree up angle);
• The Rafale (from horizontal flight)^{[citation needed]};
• The F/A-18E/F (from horizontal flight).^{[citation needed]}

Thrust vectoring aircraft, who should be able to perform this maneuver more easily (though note that the air intake still needs to be able to handle the air inflow) are:

• The Su-27 'Flanker' family is often equipped with TVC;
• The Mig-29 'Fulcrum' has a variant with TVC;
• The Su-47 'Berkut' Was to be equipped with TVC;
• The MiG 1.42 Was to be equipped with TVC;
• The Eurofighter Typhoon May be equipped with TVC at a later date;
• The F-22 Raptor;
• The F-15 ACTIVE;
• The F-16 MATV/VISTA;
• The NASA Rockwell-MBB X-31

Maneuvers that are related to the Cobra include the Cobra Turn and the Kulbit.
