A study of the use of experimental stability derivatives in the calculation of the lateral disturbed motions of a swept-wing airplane and comparison with flight results /

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.NACA TN No. 2013."January 1950."Includes bibliographical references.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.
