Download or read book Tensile Properties of 7075 T6 and 2024 T3 Aluminum alloy Sheet Heated at Uniform Temperature Rates Under Constant Load written by George J. Heimerl and published by . This book was released on 1955 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented of tests to determine the effect of heating at uniform temperature rates from 0.2 degrees to 100 degrees F. per second on the tensile properties of 7075-T6 d(75s-T6) and 2024-T3 (24s-T3) aluminum-alloy sheet under constant-load conditions. Yield and rupture stresses, obtained under rapid-heating conditions, are compared with results of elevated-temperature stress-strain tests for 1/2-hour exposure. Master yield-and-rupture-stress curves based on linear temperature-rate parameter are presented with which yield and rupture stresses or temperatures may be predicted for these materials for temperature rates from 0.2 to 100 degrees F per second. A description of the test equipment is included.

This book was released on 1955 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented of some rapid-heating tests of some sheet materials - 7075-T6 and 2024-T3 (formerly 75S-T6 and 24S-T3, respectively) aluminum alloys, Inconel, and RS-120 titanium alloy - which are part of an investigation of a number of structural materials. The materials were tested at temperature rates from 0.2 degree F to 100 degrees F per second under constant-load conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The frequency characteristics and statistical properties of the buffet loads measured on the unswept wing and tail of a fighter airplane have been studied in the stall and in the shock regime. The results indicate that the wing loads in buffeting can be treated as the Gaussian response of a simple elastic system. The tail loads appear to represent a more complicated pattern.

Download or read book Advances in Space Science and Technology written by Frederick I. Ordway and published by Academic Press. This book was released on 2014-12-02 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Space Science and Technology, Volume 8 presents the possibility that what is recognized as lunar cratering was caused by endogenous, volcanic activity rather than by the more widely accepted meteoritic impact mechanism. This book provides an introduction to the technology of rocketry. Organized into four chapters, this volume begins with an overview of lunar volcanism and the interpretation of the widespread phenomenon of cratering. This text then provides a comprehensive examination of one of the major components of the solid propellant rocket. Other chapters consider the many problems associated with design, construction, and testing of motor cases of the solid propellant rocket. This book presents as well a thorough examination of interplanetary mission planning covering such vital elements as the process of mission decision making based on model theory. The final chapter deals with the exploration of the planet Mars. This book is a valuable resource for geoscientists, astronomers, and geologists.

Nielsen and published by . This book was released on 1956 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: The wing-body interference theory of NACA TN 2677 applied to symmetrical wings in combination with quasi-cylindrical bodies permits the direct calculation of pressure-distribution changes produced by body shape changes. This theory is used to determine the relative magnitued of the wave-drag reduction produced by changes in cylinder cross-sectional area and that produced changes in cross-sectional shape (without change in area). The body distortion is expressed as a Fourier series, and an integral equation is derived for the body shape for minimum drag for each Fourier component. Thus the wave-drag reductions for the various Fourier harmonics are independent and additive.
