To break out of an established spin, the rudder must be capable of producing sufficient yawing moment to slow the spin rate and initiate a successful recovery. We will learn more about'spin recovery when we discuss the spinning motion in Chapter 7. 3.5.6 Rudder-Fr€e Directional Stallu7ity 8r f ~g p ,8 T2 <Ti Fig.3.87 Asymmetric power effects. (3.322) In sideslipping motion, if the rudder is left free to float (pilot's foot off the rudder pedal), it will assume a condition such that the net hinge moment is zero. This position is called the floating angle of the rudder and is grven by . AIAA EDUCATION SERIES ., o..
