Description: At the request of the Bureau of Aeronautics, Navy Department, an investigation of the low-speed, power-off stability and control characteristics of a 1/10-scale model of the McDonnell XF3H-1 airplane has been made in the Langley free-flight tunnel. Flight tests of the model in the clean and in the slats-and-flaps-extended conditions were made over a lift-coefficient range from about 0.5 through the stall. Only low-altitude conditions were simulated and no attempt was made to determine the effect on the stability characteristics of freeing the controls. Static force tests were made to determine the static longitudinal and lateral stability derivatives and rotary force tests were made to determine the dynamic rolling derivatives. Calculations were also made to determine the damping of the lateral oscillation for correlation with the flight results.
