Mathematical modeling and response evaluation for the fluctuating pressures of aircraft buffeting by John C Houbolt( Book )

5 editions published in 1975 in English and held by 14 WorldCat member libraries worldwide

The report reviews the mathematical modeling of pressure fluctuations in various problems of turbulent flow. Emphasis is on statistical descriptions. The models reviewed are then used to synthesize a mathematical model describing turbulent pressure fluctuations on a buffeting wing. A method of evaluation of structural response to buffet is developed and an example of the method is given. Verification tests of the method are invited
Some landing studies pertinent to glider-reentry vehicles by John C Houbolt( Book )

3 editions published in 1960 in English and held by 13 WorldCat member libraries worldwide

"Results are presented of some landing studies that may serve as guidelines in the consideration of landing problems of glider-reentry configurations. The effect of the initial conditions of sinking velocity, angle of attack, and pitch rate on impact severity and the effect of locating the rear gear in various positions are discussed. Some information is included regarding the influence of landing-gear location on effective masses. Preliminary experimental results on the slideout phase of landing include sliding and rolling friction coefficients that have been determined from tests of various skids and all-metal wheels."

An investigation has been made f o r determining the minimum number of passive satellites i n near-earth orbits required t o provide given percentages of communication time between two selected ground stations. The study is limited to the geometrical and probability aspects of the problem. An application of the analysis i s made f o r an assumed transatlantic communication system. The satellites are considered t o be i n circular, randomly spaced orbits with fixed inclination and altitude considered range from 1,000 t o 3,000 statute miles
Cross-spectral functions based on von Karman's spectral equation by John C Houbolt( Book )

3 editions published in 1972 in English and held by 11 WorldCat member libraries worldwide

Cross-spectral functions for the vertical and longitudinal components of turbulence of a two-dimensional gust field are derived from the point correlation function for turbulence due to von Karman. Closed form solutions in terms of Bessel functions of order 5/6 and 11/6 are found. An asymptotic expression for large values of the frequency argument, and series results for small values of frequency, are also given. These results now form the base for studying the effect of spanwise variations in turbulence for a turbulence environment which is characterized by the von Karman isotropic spectral relations. Previous studies were based mainly on the Dryden-type spectral representation
Differential equations of motion for combined flapwise bending, chordwise bending, and torsion of twisted nonuniform rotor blades by John C Houbolt( Book )

8 editions published between 1957 and 1958 in English and held by 11 WorldCat member libraries worldwide

The differential equations of motion for the lateral and torsional deformations of twisted rotating beams are developed for application to helicopter rotor and propeller blades. No assumption is made regarding the coincidence of the neutral, elastic, and mass axes, and the generality is such that previous theories involving various simplifications are contained as subcases to the theory developed and presented in this paper. Special attention is given to coupling terms not found in previous theories, and methods of solution of the equations of motion are indicated by selected examples
A recurrence matrix solution for the dynamic response of aircraft in gusts by John C Houbolt( Book )

6 editions published between 1950 and 1951 in English and held by 10 WorldCat member libraries worldwide

Through the use of difference equations and matrix notation a systematic procedure is developed for the calculation of the structural response of an aircraft flying through a gust. The method takes into account wing bending and twisting flexibilities, fuselage flexibility, vertical and pitching motion of the airplane, and some tail forces. Strip theory is used, but approximate three-dimensional and compressibility corrections can be made without difficulty. Either sharp-edge or arbitrary gusts may be treated
A Method for determining the column curve from tests of columns with equal restraints against rotation on the ends by Eugene E Lundquist( Book )

2 editions published in 1943 in English and held by 5 WorldCat member libraries worldwide

The results are presented of a theoretical study for the determination of the column curve from tests of column specimens having ends equally restrained against rotation. The theory of this problem is studied and a curve is shown relating the fixity coefficient to the critical load, the length of the column, and the magnitude of the elastic restraint. A method of using this curve for the determination of the column curve for columns with pin ends from tests of columns with elastically restrained ends is presented. The results of the method as applied to a series of tests on thin-strip columns of stainless steel are also given
Correlation of calculation and flight studies of the effect of wing flexibility on structural response due to gusts by John C Houbolt( Book )

4 editions published in 1953 in English and held by 5 WorldCat member libraries worldwide

Studies made to evaluate the influence of wing bending flexibility on the structural response to gusts of two twin-engine transports and one four-engine bomber are summarized. The studies encompass some previously reported and some new flight studies, some calculation studies based on discrete- or single-gust encounter, and some new calculation studies for continuous-turbulence encounter, based on the methods of generalized harmonic analysis. It is shown that the discrete-gust approach reveals the general nature of the flexibility effects and leads to qualitative correlation with flight results. The studies based on the harmonic-analysis approach show good quantitative correlation with flight results and allow for a much greater degree of resolution of the flexibility effects. A good agreement shown suggests that a suitable approach for calculating flexibility effects is now available

Critical combinations of shear and transverse direct stress for an infinitely long flat plate with edges elastically restrained against rotation by S. B Batdorf( Book )

4 editions published between 1945 and 1946 in English and held by 4 WorldCat member libraries worldwide

An exact solution and a closely concurring approximate energy solution are given for the buckling of an infinitely long flat plate under combined shear and transverse direct stress with edges elastically restrained against rotation. It was found that an appreciable fraction of the critical stress in pure shear may be applied to the plate without any reduction in the transverse compressive stress necessary to produce buckling. An interaction formula in general use was shown to be decidedly conservative for the range in which it is supposed to apply
On spectral analysis of runway roughness and loads developed during taxiing by John C Houbolt( Book )

2 editions published in 1955 in English and held by 4 WorldCat member libraries worldwide

The application of the techniques of generalized harmonic analysis to the airplane taxiing problem is considered rather briefly in this paper. Some previous results on runway roughness are reviewed, and some results obtained from taxiing tests of a large airplane are given
Critical stress of plate columns by John C Houbolt( Book )

3 editions published in 1950 in English and held by 4 WorldCat member libraries worldwide

An exact solution is given for the elastic buckling stress of a flat rectangular plate with simply supported ends when loaded as a column, and an energy solution in which power series and undetermined multiplieres are used is made for the case of fixed ends. The critical stress is given in terms of the Euler column-buckling value of the load multiplied by a coefficient which depends on the width-length ratio of the plate. A point of theoretical interest on the buckling of a very wide plate is presented
