Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2019-07-30 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the design of optimal trajectories for space maneuver vehicles (SMVs) using optimal control-based techniques. It begins with a comprehensive introduction to and overview of three main approaches to trajectory optimization, and subsequently focuses on the design of a novel hybrid optimization strategy that combines an initial guess generator with an improved gradient-based inner optimizer. Further, it highlights the development of multi-objective spacecraft trajectory optimization problems, with a particular focus on multi-objective transcription methods and multi-objective evolutionary algorithms. In its final sections, the book studies spacecraft flight scenarios with noise-perturbed dynamics and probabilistic constraints, and designs and validates new chance-constrained optimal control frameworks. The comprehensive and systematic treatment of practical issues in spacecraft trajectory optimization is one of the book’s major features, making it particularly suited for readers who are seeking practical solutions in spacecraft trajectory optimization. It offers a valuable asset for researchers, engineers, and graduate students in GNC systems, engineering optimization, applied optimal control theory, etc.

Available in PDF, EPUB and Kindle. Book excerpt: One of the most important aspects of preliminary interplanetary mission planning entails designing a trajectory that delivers a spacecraft to the required destinations and accomplishes all the objectives. The design tool described in this thesis allows an investigator to explore various interplanetary trajectories quickly and easily. The design tool employs the patched conic method to determine heliocentric and planetocentric trajectory information. An existing Lambert Targeting routine and other common algorithms are utilized in conjunction with the design tool's specialized code to formulate an entire trajectory from Earth departure to arrival at the destination. The tool includes many options for the investigator to accurately configure the desired trajectory, including planetary gravity assists, deep space maneuvers, and various departure and arrival conditions. The trajectory design tool is coded in MATLAB, which provides access to three dimensional plotting options and user adaptability. The design tool also incorporates powerful MATLAB optimization functions that adjust trajectory characteristics to find a configuration that yields the minimum spacecraft propellant in the form of change in velocity.

Book excerpt: The purpose of this Mission Design Handbook is to provide trajectory designers and mission planners with graphical information about Earth to Mars trajectory opportunities for the years of 2026 through 2045. The trajectory data used to create the following opportunity contour plots was generated using MIDAS, a patched conic interplanetary trajectory optimization program that is able to optimize the times of specified trajectory events and other trajectory parameter. The plots, displayed on a departure date/arrival date mission space, show departure energy, right ascension and declination of the launch asymptote, and target planet hyperbolic arrival excess speed, V(sub infinity), for each launch opportunity. Trajectory contour plots are particularly important in the beginning stages of mission design as valuable tools that display the interplanetary flight path characteristics for a particular launch opportunity to Mars. The use of these contour plots is an important first step for determining initial optimal launch opportunities for interplanetary missions. They also serve as good approximations for directional values of the launch asymptote vector, target planet (Mars) arrival excess velocities, and total mission flight time. These plots allow a mission designer to determine the basic requirements for an Earth to Mars transfer vehicle as well as a preliminary estimate of the required propellant load. Provided in this study are two sets of contour plots for each launch opportunity. The first set of plots shows Earth to Mars ballistic trajectories without the addition of any deep space maneuvers. The second set of plots shows Earth to Mars transfer trajectories with the addition of deep space maneuvers, which further optimize the determined trajectories. Providing two sets of plots for each opportunity allows mission planners the ability to compare and contrast different mission architectures.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: In recent years space exploration has become more and more prolific. Its nature has changed, from a public state-funded (rather unusual) activity with a main goal of challenging human and physical barriers to a private industry that has seen the opportunity to take advantage of resources outside Earth. An industry that could provide the solution for the unsustainable demand in energy and basic resources generated by an exponentially increasing population. Certainly, space exploration is nowadays far away from overtaking long ago established industries such as fossil fuels. Why chasing an asteroid when you could dig oil out on Earth and at lower costs? The answer is simple: one day no resources will be left. Several companies dedicated to space exploration and exploitation do have scheduled projects for the years to come, and mission design is key for success. Natural Gravity Assist is just one of the many different approaches a space mission can implement, depending on the size of the payload (so, consequently the spacecraft), the trajectory and celestial bodies that affect it, or even its primary goal: a satellite probe for a first scientific scanning or a two-way mission involving launches and landings? Nevertheless, implementing the Natural Gravity Assist manoeuvre is a paramount contribution: using the gravitational field of other planets allows to shape the trajectory and even more remarkable, it saves fuel. One can find a huge amount of research papers and literature dealing with the Natural Gravity Assist problem and formulation, however, those solutions are predominantly in the form of scalar equations, crowded with angles and impossible to intuitively imagine the geometry. In this paper a new analytic model is proposed relying on vector algebra making it more robust, concise and elegant. This method is tested with benchmark runs reproducing the well-known Voyager 1 mission and later on obtaining by optimization (again) Voyager 1, Voyager 2 and Mariner 10. Eventually, two asteroid-rendezvous missions (to Ryugu and Nereus, both asteroids being a current target for mining companies) are simulated. Benchmark runs successfully achieve to reproduce the real missions while asteroid rendezvous missions improve considerably fuel consumption in contrast to direct transfers. However, the results per se do not constitute the most substantial part of this research, but the restrictions, considerations and limitations around them. All of these three set a starting point for other research branches and a deeper understanding of celestial mechanics problems, simultaneous optimization for many variables, search space pruning, etc.

Download or read book Design of Interplanetary Trajectories with Multiple Synergetic Gravitational Assist Maneuvers Via Particle Swarm Optimization written by Matthew Shaw and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The design capacity for synergetic gravity assists (powered flyby's) changes the type of possible optimal trajectories to distant planets. Heuristic optimization methods have potential to produce useful trajectories for design purposes. The application of Particle Swarm Optimization (PSO) is used to determine optimal mission trajectories from Earth to planets of interest, subject to synergetic gravity assist maneuver(s) in between. In order to verify the results from PSO, past missions are re-examined from a new design perspective. The trajectories designed by aid of PSO are compared to the trajectories involving the real mission dates. Test results are obtained for Voyager 1, Voyager 2, and Cassini. The results closely resemble those of actual mission data, providing support for the new design method involving PSO and synergetic gravitational assists. The computation of these solutions offers the unique benefit of costing one to two minutes of wall clock time with standard desktop or laptop computing systems. In addition to the past missions that are considered for re-design, the work then extends the design method to a newly proposed multiple gravity-assist mission from Earth to Saturn that could take place within the next few years. Two different mission timelines are considered. Direct routes and multiple gravity assist (MGA) routes to Saturn are compared. The best solutions from PSO for the MGA routes are on an order of one half to one third the propellant cost as compared to the direct routes for the launch and arrival dates chosen. Finally, consideration for promising future research directions involving PSO and synergetic gravity assist maneuvers is discussed.
