This book was released on 1970 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boundary-layer transition by the sublimation and impact-pressure techniques and force tests have been performed on three Haack-Adams bodies of revolution of fineness ratios 7, 10, and 13 at zero angle of attack for free-stream Mach numbers of 2.00, 2.75, and 4.63 and a range of Reynolds numbers based on model length of 6 to 15 X 10(to the 6 power) with and without a roughness strip. The grit method of inducing turbulence was found to provide for a nearly complete turbulent flow over the models at the lower Mach numbers and higher Reynolds numbers considered in this study while the amount of trip drag was less than 8 percent of the model drag with transition fixed. A method of interpreting sublimation data was discussed and used and the results compared well with the impact-pressure results.

This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method to determine the aerodynamic forces acting on oscillating pointed bodies of revolution in transonic-supersonic flight has been developed. The nonlinear equation for the mean-flow perturbation potential and the time linearized equation for the cross-flow perturbation potential are both of hyperbolic type, for the Mach number range of interest, and have been solved by the method of characteristics. The method is valid for arbitrary frequencies of oscillation and can be applied for rigid or flexible body motions. Results are presented for the stability force coefficients, unsteady pressure distributions and shock deformations for various body shapes and Mach numbers.

This book was released on 1950 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of large-scale high-speed computing machines, it has become feasible to solve certain supersonic flow problems by numerical methods using the exact hydrodynamical equations instead of resorting to linearization or graphical methods. This report describes in detail one such numerical method; namely, an efficient form of the method of characteristics. Characteristic equations are derived for supersonic, steady, inviscid, isoenergetic flows in terms of a variety of dependent variables. A discussion is given of several methods of numerically solving systems of 1st order ordinary differential equations, such as are encountered in the Taylor-Maccoll and corner processes. The other computations involve approximating partial derivatives by difference quotients and solving on a finite grid of points. Solutions are derived for the cases in which the derivatives are approximated to 1st, 2nd, and 3rd orders. An empirical study is made of the error due to the introduction of finite differences. This is based on the results of a particular calculation performed on the ENIAC. It is shown that a knowledge of the nature of the errors leads to a procedure for extrapolation to zero grid size, which reduces by a factor of ten the total labor required to obtain a solution correct to about four significant figures.

Download or read book Supersonic Flow with Vorticity about a Slightly Yawing Body of Revolution written by W. C. Carter and published by . This book was released on 1952 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steady inviscid flow about a slightly yawing body of revolution has been approximated by a perturbation of the axisymmetric flow about the same body at the same free stream Mach Number. It is generally (but not always) assumed that the products of the perturbations are negligible. The hyperbolic system of partial differential equations of motion is transformed into characteristic form, then the perturbations are expanded in Fourier series, most of whose terms are shown to vanish. The remaining perturbation coefficients satisfy a linear homogeneous system of partial differential equations. The procedure has been developed with sufficient generality to include vorticity, and is applicable to bodies whose meridian sections have discontinuous slopes. Pressure ratios, normal force coefficients, and center of pressure positions calculated by this method for a 10 degree semi-angle cone cylinder with free stream Mach Number of 1.72 are in good agreement with wind tunnel and free flight data for yaws not exceeding five degrees.
