Chemical Rockets: Performance Prediction and Internal Ballistics Design by Subramaniam Krishnan
English | PDF | 2020 | 538 Pages | ISBN : 3030269647 | 5.5 MB

The purpose of this book is to discuss, at the graduate level, the methods of performance prediction for chemical rocket propulsion. A pedagogical presentation of such methods has been unavailable thus far and this text, based upon lectures, fills this gap. The first part contains the energy-minimization to calculate the propellant-combustion composition and the subsequent computation of rocket performance.

Permanent Magnet Spherical Motors: Model and Field Based Approaches for Design, Sensing and Control By Kun Bai
English | EPUB | 2018 | 170 Pages | ISBN : 9811079617 | 5.2 MB

This book introduces and illustrates modeling, sensing, and control methods for analyzing, designing, and developing spherical motors. It systematically presents models for establishing the relationships among the magnetic fields, position/orientation and force/torque, while also providing time-efficient solutions to assist researchers and engineers in studying and developing these motors. In order to take full advantage of spherical motors’ compact structure in practical applications, sensing and control methods that utilize their magnetic fields and eliminate the need to install external sensors for feedback are proposed.
