Lifting-surface-theory values of the damping in roll and of the parameter used in estimating aileron stick forces by Robert S Swanson ( Book )
4 editions published in 1945 in English and held by 5 WorldCat member libraries worldwide
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 the compressibility were included in the computations
Analysis of available data on the effectiveness of ailerons without exposed overhang balance by Robert S Swanson ( Book )
4 editions published in 1944 in English and held by 5 WorldCat member libraries worldwide
A considerable amount of two- and three-dimensional data on the effectiveness of ailerons without exposed overhang balance has been collected and analyzed. The trends indicated by the analysis have been summarized in the form of a few approximate rules concerning the effectiveness parameter (at constant lift): Thickening and beveling the trailing edge (as measured by the trailing edge angle) will generally reduce the effectiveness about 0.3 percent per degree of bevel for ailerons sealed at the hinge axis and about 0.6 percent per degree of bevel for unsealed ailerons
An electromagnetic-analogy method of solving lifting-surface-theory problems by Robert S Swanson ( Book )
3 editions published in 1945 in English and held by 5 WorldCat member libraries worldwide
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 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
A Lifting-surface-theory solution and tests of an elliptic tail surface of aspect ratio 3 with a 0.5-chord 0.85-span elevator by Robert S Swanson ( Book )
2 editions published in 1947 in English and held by 4 WorldCat member libraries worldwide
An electromagnetic-analogy model of the vortex load, estimated from lifing-line theory with an arbitrary fairing near the elevator tip, on a thin elliptic horizontal tail surface of aspect ratio 3 with a 0.5-chord 0.85-span plain elevator was constructed and tested. The aspect-ratio corrections to the lift and hinge moments were calculated from the measured results
Lifting -surface-theory aspect-ratio corrections to the lift and hinge-moment parameters for full-span elevators on horizontal tail surfaces by Robert S Swanson ( Book )
2 editions published in 1947 in English and held by 4 WorldCat member libraries worldwide
A limited number of lifting-surface-theory solutions for wings with chordwise loadings resulting from angle of attack, parabolic-arc camber, and flap deflection are now available. These solutions were studied with the purpose of determining methods of extrapolating the results in such a way that they could be used to determine lifting-surface-theory values of the aspect-ratio corrections to the lift and hinge-moment parameters for both angle-of-attack and flap-deflection-type loading that could be used to predict the characteristics of horizontal tail surfaces from section data with sufficient accuracy for engineering purposes. Such a method was devised for horizontal tail surfaces with full-span elevators. In spite of the fact that the theory involved is rather complex, the method is simple to apply, and may be applied without any knowledge of lifting-surface-theory

Wind-tunnel tests of an NACA 23021 airfoil equipped with a slotted extensible and a plain extensible flap by Thomas A Harris ( Book )
1 edition published in 1940 in English and held by 3 WorldCat member libraries worldwide
The results showed that the basic airfoil gave the lowest profile-drag coefficients over the low lift range, the airfoil with the plain extensible flap gave the lowest profile-drag coefficients over the high lift range. The airfoil with the slotted extensivle flap had the same maximum lift at a flap deflection of 25 degrees as the airfoil with the plain extensible flap had at a flap deflection of 60 degrees. The results of comparisons of the airfoil pitching-moment coefficients obtained with the two types of flap are dependent upon the basis chosen for comparison

Determination of the stability and control characteristics of airplanes from tests of powered models by Isidore G Recant ( Book )
3 editions published in 1942 in English and held by 3 WorldCat member libraries worldwide
A technique of testing wind-tunnel powered models has been developed as a result of experience gained in the investigation of the static longitudinal and lateral stability and control characteristics of several powered models in the NACA 7- by 10-foot wind tunnel. As an important part of this technique, a minimum program of the tests considered necessary to specify satisfactorily the static stability and control characteristics for present-day airplanes has been tentatively established
Wind-tunnel tests of a twin-engine model to determine the effect of direction of propeller rotation on the static-stability characteristics by Francis M Rogallo ( Book )
2 editions published in 1943 in English and held by 2 WorldCat member libraries worldwide
Tests were made in the LMAL 7- by 10-foot tunnel to determine the effect of direction of propeller rotation on the static longitudinal- and lateral-stability characteristics of the 1/10-scale model of the North American B-28 airplane
Wind-tunnel investigation of an NACA 23021 airfoil with two sizes of balanced split flaps by Robert S Swanson ( Book )
2 editions published in 1941 in English and held by 2 WorldCat member libraries worldwide
An investigation has been made in the NACA 7- by 10-foot wind tunnel of a large-chord NACA 23021 airfoil with a 15-percent-chord and a 25-percent-chord balanced split flap of Clark Y profile, to determine the aerodynamic section characteristics of the airfoil-flap combinations as affected by the size, nose location, and deflection of the flaps. Section lift, drag, and pitching-moment characteristics are presented in the form of contours of flap nose location for given values of the lift, drag, and pitching-moment coefficients and complete aerodynamic section characteristics are presented for four representative locations of each flap. The two balanced split flaps are compared with a slotted-flap arrangement in a previous investigation
Jet-boundary corrections to a yawed model in a closed rectangular wind tunnel by Robert S Swanson ( Book )
2 editions published in 1943 in English and held by 2 WorldCat member libraries worldwide
General formulas are derived for determining the jet-boundary corrections to the angle of attack, the drag coefficient, the downwash, the pitching-, rolling-, and yawing-moment coefficients of complete powered yawed models, and to the increments of rolling- and yawing-moment coefficients due to the ailerons on yawed models. Numerical values of the jet-boundary induced velocities and the corresponding corrections are calculated for a typical powered model yawed 20 degrees in a 7- by 10-foot closed wind tunnel. The results of the calculations are compared with the results for the unyawed model
Wind-tunnel calibration and correction procedures for three-dimensional models by Robert S Swanson ( Book )
2 editions published in 1944 in English and held by 2 WorldCat member libraries worldwide
Detailed methods are presented for determining the corrections to results from wind-tunnel tests of three-dimensional models for the effects of the model-support system, the nonuniform air flow in the tunnel, and the tunnel walls or jet boundaries. The procedures for determining the corrections are illustrated by equations and the required tests are discussed. Particular attention is given to the parts of the procedures dealing with drag measurements. Two general methods that are used for determining and applying the corrections to force tests are discussed. Some discussion is also included of the correction procedures to be used for wake survey tests. The methods described in this report apply only to tests at subcritical speeds
Limitations of lifting-line theory for estimation of aileron hinge-moment characteristics by Robert S Swanson ( Book )
2 editions published in 1943 in English and held by 2 WorldCat member libraries worldwide
Hinge-moment parameters for several typical ailerons were calculated from section data with the aspect-ratio correction as usually determined from lifting-line theory. The calculations showed that the agreement between experimental and calculated results was unsatisfactory. An additional aspect-ration correction, calculated by the method of lifting-surface theory, was applied to the slope of the curve of hinge-moment coefficient against angle of attack at small angles of attack. This so-called streamline-curvature correction brought the calculated and experimental results into satisfactory agreement
Jet-boundary corrections to the downwash behind powered models in rectangular wind tunnels with numerical values for 7- by 10-foot closed wind tunnels by Robert S Swanson ( Book )
2 editions published in 1942 in English and held by 2 WorldCat member libraries worldwide
Methods are presented for determining the jet-boundary corrections to the downwash behind models in rectangular wind tunnels. The methods take into account the tunnel dimensions, the type of jet, the span loading of the model, the geometric position of the wing and of the tail in the tunnel, the displacement of the wing wake, and the effect of slipstream. A correction to the lift of the wing due to the curvature of the streamlines was determined from the downwash correction calculations and is included in the appendix. Numerical values of the downwash correction factors for 7- by 10-foot closed wind tunnels are presented in the form of graphs
Wind-tunnel development of a plug-type spoiler-slot aileron for a wing with a full-span slotted flap and a discussion of its application by Francis M Rogallo ( Book )
2 editions published in 1941 in English and held by 2 WorldCat member libraries worldwide
Wind-tunnel tests were made regarding aileron to determine static rolling, yawing, and hinge moments for several angles of attack and flap deflections. Aileron is essentially a tapered plug which is fitted into slot through wing and conforms to external wing contour when in neutral position. Results indicated aileron has negligible drag in neutral position and provides satisfactory lateral control for airplanes equipped with full-span slotted flaps; it is unsatisfactory with full-span split flap. Application of aileron to pursuit type airplane is considered and resultant characteristics are estimated
