Measurements of Flying Qualities of an F-47D-30 Airplane to Determine Lateral and Directional Stability and Control Characteristics

Abstract

Flight tests were made to determine the lateral and directional stability and control characteristics of an F-47D-3O airplane. The results of these tests showed the airplane stability to be weak directionally in low-speed conditions. In the power-off landing condition and high-speed clean conditions, the directional stability was satisfactory. The effect,of increasing the altitude was to decrease the stability. The general characteristics of the aileron control were satisfactory, but the values of the aileron effectiveness were low and failed to meet the Air Force handling-qualities requirements. The rudder-force trim change with change in power and speed was rather large and objectionable to the pilot, although the forces encountered did not exceed the specified requirements.
