Kulbit

The "Kulbitinscy" (or simply, "Kulbit") is an aerial maneuver developed by Russian pilots, in which the aircraft performs an incredibly tight diametered loop, often not much wider than the length of the aircraft itself. It is an example of post-stall maneuvering, a type of supermaneuverability. 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 decelerates the aircraft 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.
