The results of an experimental and theoretical investigation of the effects of large artificial variations of four rotary stability derivatives on the dynamic lateral stability and control of a 45 degree sweptback-wing airplane model are presented. The experimental results are presented mainly in the form of flight ratings for stability, control, and general flight behavior. Calculations of period and damping and of the response of rolling and yawing disturbances are also presented.

Experimentally determined lateral-stability derivatives of a swept-wing airplane are presented to show effects of slots, flaps, propeller, and ventral fins and are sued in calculations of a number of lateral disturbed motions. The calculated motions are compared with those obtained in flight tests to determine the applicability of the experimental stability derivatives . The effects of nonlinearity of some of the aerodynamic forces with sideslip are shown by a few supplemental calculations.
