__Orbital Mechanics for Engineering Students, Fourth Edition,__ is a key text for students of aerospace engineering. While this latest edition has been updated with new content and included sample problems, it also retains its teach-by-example approach that emphasizes analytical procedures, computer-implemented algorithms, and the most comprehensive support package available, including fully worked solutions, PPT lecture slides, and animations of selected topics. Highly illustrated and fully supported with downloadable MATLAB algorithms for project and practical work, this book provides all the tools needed to fully understand the subject. * Provides a new chapter on the circular restricted 3-body problem, including low-energy trajectories * Presents the latest on interplanetary mission design, including non-Hohmann transfers and lunar missions * Includes new and revised examples and sample problems Cover......Page 1 Orbital Mechanics forEngineering Students......Page 3 Copyright......Page 4 Dedication......Page 5 Preface......Page 6 Acknowledgements......Page 8 Vectors......Page 9 Kinematics......Page 17 Mass, force, and Newtons law of gravitation......Page 22 Newtons law of motion......Page 25 Time derivatives of moving vectors......Page 29 Relative motion......Page 34 Numerical integration......Page 42 Runge-Kutta methods......Page 46 Heuns predictor-corrector method......Page 52 Runge-Kutta with variable step size......Page 53 Problems......Page 57 References......Page 62 Equations of motion in an inertial frame......Page 63 Equations of relative motion......Page 71 Angular momentum and the orbit formulas......Page 75 The energy law......Page 83 Circular orbits (e=0)......Page 84 Elliptical orbits (0
