A method is described for measuring the dynamic stability derivatives of a model airplane in a wind tunnel. The characteristics features of this system are that single-degree-of-freedom oscillations were used to obtain combinations of rolling, yawing, and pitching motions; that the oscillations were excited and controlled by velocity feedback which permitted operation under conditions unfavorable for more conventional types of oscillatory testing; and that data processing was greatly simplified by using analog computer elements in the strain-gage circuitry.

An investigation was conducted in the Langley high-speed 7- by 10-foot tunnel to determine the horizontal- and vertical-tail contributions to the static lateral stability of a complete-model swept-wing configuration at high subsonic speeds. The results indicate that, in a general, Mach number effects within the range studied and wing effects on the tail contribution were small and the overall trends of the data of the present investigation agreed with those which have been established at low speeds.

An investigation was made in the Langley stability tunnel to determine the effects of leading-edge radius and profile thickness on the oscillatory lateral stability derivatives for a series of delta wings with 60 degrees of leading-edge sweep. The wings were oscillated in yaw about their vertical axes.

The accuracy of the system was first investigated in tests under idealized condtions in which the aerodynamic derivatives were simulated by the action of gyroscopes and magnetic dampers. Later, the system was investigated in a high-speed wind tunnel using a simple model for which aerodynamic derivatives could be estimated.
