This book examines ascent trajectories of space launch vehicles and re-entry trajectories of space capsules. The decommissioned SCOUT is used as a reference launcher and the reader will be introduced to various and detailed aspects of a launch vehicle that are not generally available in the literature, since this information is limited to internal industry and agency reports. The SCOUT data are used here as a study case and the reader will be able to generate a complete numerical code using the general equations of flight introduced in different reference systems, including the time-dependent parameters representing the launcher and its environment with a high degree of accuracy. The guidance parameters for injection into orbits of different semiaxes, eccentricities and inclinations are determined by guessed values obtained by original analytical formulae. These formulae allow a fast and sufficiently accurate design of the rocket trajectory within the atmosphere; in the exo-atmospheric flight closed form solutions of the optimal problem of injection into orbit are provided. The second part of the book deals with re-entry trajectories. Basic analytical formulae for ballistic reentry are presented to evaluate the reentry trajectory and the capsule design in terms of critical parameters such as temperature and load peak. Entry corridors for ballistic reentry trajectories are then determined for various planets with atmospheres. The effect of lift is analysed to increase the entry corridors and guide the capsule to a target landing point. Autonomous and real-time guidance algorithms are developed for capsule of low aerodynamic efficiency and winged re-entry vehicles.

This monograph investigates the trajectory optimization problems of low- and finite-thrust aerospace vehicles and spacecraft using an indirect method based on the Pontryagin maximum principle, providing a methodological basis for the construction of numerical techniques that are superior in versatility and accuracy to direct methods. This book provides a theoretical explanation of the approaches used and also an extensive gallery of the results of practical numerical studies. The problem of boundary value problem convergence has been largely overcome, which has made it possible to practically automate the optimization of trajectories and to achieve a qualitative generalization with a number of fundamentally new results. Examples of practical optimization of branching trajectories of complex dynamics systems with finite and continual sets of branches, in deterministic and stochastic statements, with control constraints and phase constraints of various orders are demonstrated. An emphasis is placed on the consistent application of methods of numerical continuation with respect to a parameter to solve various problems in the flight mechanics of spacecraft with an electric propulsion system (EPS). The problems considered include the optimization of direct interplanetary flights of spacecraft with thrusters having limited power or limited thrust, of interplanetary flights of such spacecraft using gravity assisted maneuvers, of multi-orbit interorbital transfers of spacecraft with limited-thrust EPS. As a result, it was possible to develop a set of numerical continuation methods for solving a wide range of optimization problems for spacecraft trajectories with EPS with improved characteristics in terms of convergence and performance. This monograph also contains a description of many pitfalls in solving a wide range of problems of optimizing the trajectories of aerospace vehicles and recipes for effectively overcoming them.

Optimal Trajectories in Atmospheric Flight deals with the optimization of trajectories in atmospheric flight. The book begins with a simple treatment of functional optimization followed by a discussion of switching theory. It then presents the derivation of the general equations of motion along with the basic knowledge in aerodynamics and propulsion necessary for the analysis of atmospheric flight trajectories. It goes on to the study of optimal trajectories by providing the general properties of the optimal aerodynamic controls and the integrals of motion. This is followed by discussions of high subsonic and supersonic flight, and approximation techniques to reduce the order of the problem for a fast computation of the optimal trajectory. The final chapters present analyses of optimal reentry trajectories and orbital maneuvers. This book is intended as a reference text for scientists and engineers wanting to get into the subject of optimal trajectories in atmospheric flight. If used for teaching purposes, the book is written in a self-contained way so that a selective use of the material is at the discretion of the lecturer. The first 11 chapters are sufficient for a one-semester course with emphasis on optimal maneuvers of high performance aircraft.
