Principle and Application of Complementary Energy Method for Thin Homogeneous and Sandwich Plates and Shells With Finite Deflections

Description: Note presenting the principle of complementary energy in the nonlinear elasticity theory, which is shown to be derivable from the principle of potential energy by a Legendre type of transformation.

Theoretical Investigation of Subsonic Oscillatory Blade-Row Aerodynamics

Description: Note presenting a method for calculating the aerodynamic lifts and moments experienced by a cascade or two-dimensional approximation to a compressor or turbine blade row in subsonic flow under harmonic oscillation. The most significant features of the method stem from the utilization of Fourier transforms of blade pressure-jump functions. A plot is presented giving the location of resonance conditions, in general, and calculation results are reported for a configuration corresponding to the tunnel-wall interference problem which constitutes a special case of the cascade problem" (p. 1).

Longitudinal Stability in Relation to the Use of an Automatic Pilot

Description: "The effect of restraint in pitching introduced by an automatic pilot upon the longitudinal stability of an airplane has been studied. Customary simplifying assumptions have been made in setting down the equations of motion, and the results of computations based on the simplified equations are presented to show the effect of an automatic pilot installed in an airplane of known dimensions and characteristics. The equations developed have been applied by making calculations for a Clark biplane and a Fairchild 22 monoplane" (p. 1).

Corrections for Lift, Drag, and Moment of an Airfoil in a Supersonic Tunnel Having a Given Static Pressure Gradient

Description: Note presenting an analysis of the corrections for lift, drag, and moment of a two-dimensional airfoil as tested in the working section of a supersonic tunnel in which the pressure field, instead of being uniform, is characterized by gradients in the axial and transverse directions. The pressure gradients of the tunnel as well as the effect of the airfoil to be tested are regarded as perturbations of the original rectilinear flow field of given Mach number.

A Study of Poisson's Ratio in the Yield Region

Description: "In the yield region of the stress-strain curve the variation in Poisson's ratio from the elastic to the plastic value is most pronounced. This variation was studied experimentally by a systematic series of tests on several aluminum alloys. The tests were conducted under simple tensile and compressive loading along three orthogonal axes" (p. 1).

Two-Dimensional Subsonic Flow Past Elliptic Cylinder by the Variational Method

Description: "A method of solution is presented for compressible fluid flow past an elliptical cylinder by means of the variational method. The solution is obtained as a function of thickness ratio and free-stream Mach number. Numerical examples are carried out for several thickness ratios and Mach numbers and the results are compared with those obtained by other methods" (p. 1).

Application of Variational Methods to Transonic Flows With Shock Waves

Description: Note presenting a modification of certain variational methods for the approximate solution of subsonic and transonic flows to compensate for the fact that those methods fail as soon as shock waves occur. By applying a variational principle to the regions of flow behind shock waves and Bateman's original principle to the other regions in the fluid, shock equations can be directly obtained.

Compressive and Torsional Buckling of Thin-Wall Cylinders in Yield Region

Description: Note presenting a general set of equilibrium differential equations for the plastic buckling of cylinders, which are based on assumptions that have led to the best agreement between theory and test data on inelastic buckling of flat plates. Test data are presented which indicate satisfactory agreement with the theoretical plasticity-reduction factors in most cases. Some of the topics addressed include compressive buckling and torsional buckling.

A Photoelectric Hygrometer

Description: Note presenting an instrument that measures small absolute humidity changes by photoelectric examination of the 9440 angstrom units absorption band of water vapor. The instrument consists of a small source of light which sends its radiation over an air path of less than 1.5 meters to a dispersing system.

Handbook of Structural Stability Part 4: Failure of Plates and Composite Elements

Description: Available theories on failure of flat plates are reviewed, and test data on the postbuckling behavior, effective width, and failure of flat curved plates are correlated. Test data on the crippling strength of various formed and extruded shapes are reviewed, from which a generalized method of crippling analysis is formulated. This analysis is then applied to a variety of sections and materials in common use.

The effect of tip shields on a horizontal tail surface

Description: A series of experiments made in the wind tunnel of the Daniel Guggenheim School of Aeronautics, New York University, on the effect of tip shields on a horizontal tail surface are described and discussed. It was found that some aerodynamic gain can be obtained by the use of tip shields though it is considered doubtful whether their use would be practical.

Corrections for Drag, Lift, and Moment of an Axially Symmetrical Body Placed in a Supersonic Tunnel Having a Two-Dimensional Pressure Gradient

Description: Note presenting corrections for drag, lift, and moment that are derived for an axially symmetrical body placed in the test section of a supersonic tunnel on the assumption that the test section is characterized by a two-dimensional pressure field originating from construction flaws. Assuming irrotational conditions, the velocity potential of the flow around the body is expanded in a threefold manner: in powers of the thickness parameter of the body, in powers of a parameter characterized the inhomogeneity of the basic flow field, and as a Fourier series in the azimuth around the body axis.
