Interplanetary travel is a difficult task due to the high fuel mass required to reach other planets. Minimizing the cost of the manoeuvres (and, in turn, the fuel mass) is the objective preliminary mission design. During this phase, a large number of potential solutions must be evaluated quickly in search of feasible trajectories. This means computationally fast but simple models are preferred over accurate but slow models. Additionally, the process demands for an automatic execution due to the vast amount of solutions that must be evaluated. One of the major improvements regarding space travel was the discovery of the gravity assist, where a spacecraft uses the gravitational pull of a flyby planet to change its velocity with respect to the Sun. This allows reducing the amount of fuel mass, which in turn increases the science payload available for the mission. This thesis deals with the optimization of interplanetary trajectories with gravity assist. From an engineering approach, the thesis aims at producing an automatic optimizer of interplanetary trajectories with gravity assist manoeuvres aimed to preliminary mission design applications. From a scientific approach, the thesis aims at identifying key issues in the literature that allow for improvement and presenting novel implementations. Finally, the thesis has a strong educational component: the code and tools are specially focused towards an easy understanding and analysis of the underlying methods rather than producing a computationally efficient code. The result from this work is an automatic optimizer of multi gravity-assist interplanetary trajectories. The tool is fully modular and works with a double-loop approach: an outer loop obtains feasible sequences of planets using the Tisserand graph and an inner loop finds the best trajectory for each sequence using a hybrid heuristic optimizer and a patched conics method. Five key issues have been investigated and improved upon during the thesis: we provide an improved solution method for the Kepler equation, we have conducted an extensive bibliographic research of Lambert's problem and analyzed the representative methods to select the best for our application, we have recovered and improved the Lambert's problem method by Simó , we present two different models for the patched conics method, we have developed an automatic method to traverse the Tisserand graph and finally we have implemented several heuristic optimization methods and coupled them with an islands model. The resulting tool has already proved to work in operational mission design scenarios. However, it lends itself to many improvements and upgrades, in particular increasing the level of automation, improving the physical model and the patched conics method robustness, improving the visualization capabilities during the optimization stage and translating the code into compiled language to increase the computational performance with complex missions and intensive simulations.

This is a long-overdue volume dedicated to space trajectory optimization. Interest in the subject has grown, as space missions of increasing levels of sophistication, complexity, and scientific return - hardly imaginable in the 1960s - have been designed and flown. Although the basic tools of optimization theory remain an accepted canon, there has been a revolution in the manner in which they are applied and in the development of numerical optimization. This volume purposely includes a variety of both analytical and numerical approaches to trajectory optimization. The choice of authors has been guided by the editor's intention to assemble the most expert and active researchers in the various specialities presented. The authors were given considerable freedom to choose their subjects, and although this may yield a somewhat eclectic volume, it also yields chapters written with palpable enthusiasm and relevance to contemporary problems.

Reflecting the results of twenty years; experience in the field of multipurpose flights, this monograph includes the complex routes of the trajectories of a number of bodies (e.g., space vehicles, comets) in the solar system. A general methodological approach to the research of flight schemes and the choice of optimal performances is developed. Additionally, a number of interconnected methods and algorithms used at sequential stages of such development are introduced, which allow the selection of a rational multipurpose route for a space vehicle, the design of multipurpose orbits, the determination of optimal space vehicle design, and ballistic performances for carrying out the routes chosen. Other topics include the practical results obtained from using these methods, navigation problems, near-to-planet orbits, and an overview of proven and new flight schemes.

Many systems architecture optimization problems are characterized by a variable number of optimization variables. Many classical optimization algorithms are not suitable for such problems. The book presents recently developed optimization concepts that are designed to solve such problems. These new concepts are implemented using genetic algorithms and differential evolution. The examples and applications presented show the effectiveness of the use of these new algorithms in optimizing systems architectures. The book focuses on systems architecture optimization. It covers new algorithms and its applications, besides reviewing fundamental mathematical concepts and classical optimization methods. It also provides detailed modeling of sample engineering problems. The book is suitable for graduate engineering students and engineers. The second part of the book includes numerical examples on classical optimization algorithms, which are useful for undergraduate engineering students. While focusing on the algorithms and their implementation, the applications in this book cover the space trajectory optimization problem, the optimization of earth orbiting satellites orbits, and the optimization of the wave energy converter dynamic system: architecture and control. These applications are illustrated in the starting of the book, and are used as case studies in later chapters for the optimization methods presented in the book.

An authoritative reference that covers essential concepts of orbital mechanics and explains how they relate to advanced space trajectory applications Space Trajectories is the first book to offer a comprehensive exploration of orbital mechanics and trajectory optimization in a single volume. Beginning with a review of essential concepts, the book progresses to advanced space applications, highlighting methods used in today’s space missions. The contents are organized into three parts. The first part delves into free orbital motion, covering topics such as Keplerian motion, perturbed motion, the three-body problem, orbit determination, and collision risks in orbit. The second part focuses on controlled orbital motion, discussing impulsive transfer, orbital rendezvous, thrust level optimization, low-thrust transfer, and space debris cleaning. The third part examines ascent and reentry, including launch into orbit, launcher staging, analytical solutions in flat Earth, interplanetary missions, and atmospheric reentry. Each chapter is written in a modular way, featuring conclusion summaries, key points, and suggestions for further investigation. Examples are included with detailed solutions methods that readers can apply to solve their own trajectory problems. Written by an expert of the topic who has performed guidance of Ariane launchers for 30 years, Space Trajectories includes information on: Keplerian motion, motion time law, universal formulation, equinoctial parameters, and Lagrange coefficients Osculating orbit, Gauss equations, gravitational and third body perturbations, Lissajous and Halo orbits, and invariant manifolds Astrometry measurements, Kalman filtering, orbit uncertainties, and collision probability Transfer in one, two, or three impulses, minimum-energy transfer, Lambert’s problem, high- and low-thrust transfer, and interplanetary path Launch and reentry trajectories, propulsion systems, optimized thrust profiles, and launcher staging Space Trajectories is an essential reference for students and researchers aiming to quickly understand the main issues in astrodynamics and the way to design trajectories, as well as space engineers seeking to consolidate their knowledge in the field of optimization and optimal control applied to aerospace and space missions.
