Cracked role
The torn roll (English: flick roll , American: snap roll ) in aerobatics is a roll around the longitudinal axis of the aircraft that is not controlled by aileron. Instead, by quickly operating the elevator and practically at the same time abruptly deflecting the rudder, a one-sided flow separation is caused on one wing, whereby the lift on this wing collapses. Since there is now only lift on the other wing, the aircraft performs a very fast autorotation around the longitudinal axis. The ailerons are usually kept in neutral. The snapped roll is related to the spin .
The initiation of a broken roll is easy and does not require a lot of dexterity, on the contrary, with many types of aircraft even quite brutal steering deflections are necessary to bring about a clean flow stall (hence the name of the figure: the pilot has to pull the control stick backwards) when the initiation speed fits, you can't really go wrong. However, it is then much more difficult to stop the rotation exactly in the desired position.
Torn rollers put a heavy load on the aircraft structure, especially in the area of the tail unit. This figure is therefore not approved for all aerobatic aircraft.
The analogous figure with a stall at a negative angle of attack is called the pushed roller .
