Experimental Verification of the Rudder-Free Stability Theory for an Airplane Model Equipped with a Rudder Having Positive Floating Tendencies and Various Amounts of Friction

Abstract

The results of an investigation conducted in a free-flight tunnel indicate that, with negligible friction in the rudder control system, the general rudder-free stability theory adequately predicts the period and qualitatively predicts the damping of the rudder-free oscillations for the normal range of airplane and rudder parameters. If the general theory is simplified, it still adequately predicts the period and quantitatively predicts lower values of the damping of the rudder-free lateral oscillation.
