This book was released on 1961 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Entry corridors for manned vehicles returning from the moon are defined consistent with requirements for avoiding radiation exposure and for limiting values of peak deceleration. It was found that the use of lift increases the depth of the entry corridor and, hence, reduces guidance accuracy requirements. Mid-course guidance requirements appear to be critical only for the flight-path angle. Increasing the energy of the transfer orbit increases the required guidance for the flight-path angle. To correct a trajectory for an error in target perigee point, it was found that application of the corrective thrust essentially parallel to the local horizontal produces the maximum change in perigee altitude for a given increment of velocity. It was also found that the energy required to effect a given change in perigee altitude is not strongly dependent on the energy of the orbit, but it was found to vary inversely with range measured from the center of the earth. For this reason, it is important to detect and correct any errors in approach trajectory at the largest possible distance from the earth.

Available in PDF, EPUB and Kindle. Book excerpt: A symposium on Aerothermoelasticity was held to present the latest significant developments in each scientific area and engineering area that comprise the component parts of this technology. New and significant contributions were presented in four technical areas consisting of dynamic aerothermoelasticity (flutter), stability and control, thermodynamics and aerodynamics (or aerothermodynamics), and structures including material and construction concepts. Categories important and significant to each technical area are discussed state-of-the-art wise. In addition, 26 separate papers are given on items of special importance.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Control Systems: Theory and Applications, Volume 2 provides information pertinent to the significant progress in the field of automatic control. This book presents different methods for generating Liapunov functions, which is important in the analysis of nonlinear systems. Organized into five chapters, this volume begins with an overview of the reduction of the important method of Liapunov to a practical working tool for the analysis of complex nonlinear systems. This text then discusses applications of the rather powerful method of dynamic programming to a complex class of problems. Other chapters consider the mathematical theory of optimal control, which is often confronted with the task of solving a system of first-order ordinary differential equations. This book discusses as well the input–output relationship of multivariable linear systems or plants. The final chapter deals with a powerful technique for design by analysis of nonlinear systems. This book is a valuable resource for mathematicians and engineers.
