The "Kulbit" (also known as the "Frolov chakra" after Russian test pilot Yevgeni Frolov) is an aerial maneuver developed by Russian pilots in which the aircraft performs an extremely tight loop, often not much wider than the length of the aircraft itself. It is an example of post-stall maneuvering,[1] a type of supermaneuverability.[1] Like most post-stall maneuvers, it demonstrates pitch control outside of the normal flight envelope wherein pitch control is made possible by having aerodynamic flow over the aircraft's elevators or stabilators.

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.
