Summary: In order to determine the validity of sideslip data obtained in flight by the continuous-record method, sideslip data obtained from a fighter airplane in slowly increasing sideslips have been compared with sideslip data obtained from the same airplane in sideslips in which all the flight conditions were stabilized. The results of the comparison showed no essential difference in the sideslip characteristics obtained by the two flight techniques even though the continuous sideslips were p...

Summary: In order to determine the validity of sideslip data obtained in flight by the continuous-record method, sideslip data obtained from a fighter airplane in slowly increasing sideslips have been compared with sideslip data obtained from the same airplane in sideslips in which all the flight conditions were stabilized. The results of the comparison showed no essential difference in the sideslip characteristics obtained by the two flight techniques even though the continuous sideslips were purposely executed with a yawing velocity about double the usual rate of 1À per second in order to accentuate the effects of the small yawing and rolling velocities inherent in the method. Approximate theoretical calculations confirmed the experimental results but indicated that rates of yawing or rolling lower than 1À per second are desirable if the continuous-sideslip technique is employed in testing airplanes much larger than current fighters. The method of measuring sideslip characteristics under steady conditions is preferred to the method of measuring sideslip characteristics in slowly increasing sideslips when the airplane is directionally unstable, when is has a large pitching moment due to sideslip, or when a poor relationship exists among the rudder, aileron, and elevator control forces in sideslips.

Summary: An investigation was made by lifting-surface theory of a thin elliptic wing of aspect ratio 6 in a steady roll by means of the electromagnetic-analogy method. From the results, aspect-ratio corrections for the damping in roll and aileron hinge moments for a wing in steady roll were obtained that are considerably more accurate than those given by lifting-line theory. First-order effects of compressibility were included in the computations. The results obtained by lifting-surface theory i...

First-order effects of compressibility were included in the computations. The results obtained by lifting-surface theory indicate that the damping in roll for a wing of aspect ratio 6 is 13 percent less than that given by lifting-line theory and 5 percent less than that given by lifting-line theory with the edge-velocity correction derived by Robert T. Jones applied. The results are extended to wings of other aspect ratios. Also available in electronic format.FU

Summary: A method is suggested for making lifting-surface calculations by means of magnetic measurements of an electromagnetic-analogy model. The method is based on the perfect analogy between the strength of the magnetic field around a conductor and the strength of the induced-velocity field around a vortex. Electric conductors are arranged to represent the vortex sheet. The magnetic-field strength is determined by measuring, with an electronic voltmeter, the voltage induced in a small search c...

The method is based on the perfect analogy between the strength of the magnetic field around a conductor and the strength of the induced-velocity field around a vortex. Electric conductors are arranged to represent the vortex sheet. The magnetic-field strength is determined by measuring, with an electronic voltmeter, the voltage induced in a small search coil by the alternating current in the wires representing the vortex sheet. Solutions of nonlinear lifting-surface problems may be obtained by placing the conductors representing the trailing vortices along the fluid lines (Helmholtz condition). A potential-flow solution for the distortion and rolling up of the trailing-vortex sheet may be obtained. By use of the Prandtl-Glauert rule, the lifting-surface theory may be adapted to include first-order compressibility effects. Also available in electronic format.FU

Summary: In flight tests of an experimental elevator with geared tabs, a cockpit control over the tab gear ratio was found to be satisfactory for adjusting the stick force per g in turning flight according to the pilot's preference. This type of control appears to have application for increasing the center-of-gravity range for satisfactory stick forces in turning flight. Sample calculations made for a fighter airplane indicated that satisfactory stick forces in turning flight can be obtained...
