This book proposes a solution to the problem of incorrect use of automation tools to perform complex design work. Currently, a large number of start-up projects are non-professional design bureaus that show a huge amount of their achievements. In reality, most of these achievements burst like soap bubbles. This is due to the low-quality and inefficient use of information technology in this industry. The book highlights advanced information technologies in the fields of design, machine learning, and computer vision.

This open access book presents technologies and methods of lightweight system design to support future low-emission aviation in achieving climate targets. It will be shown how reduction of weight and aerodynamic drag affects the energy consumption of commercial aircraft and what characterizes lightweight system design. Methods, design principles, production technologies and options for functional integration are available for more energy-efficient aircraft. Research results from the last decade are presented, which are intended to encourage the reader to further research and, above all, to implement them in future aircraft. The Author Prof. Dr.-Ing. Martin Wiedemann heads the DLR Institute of Lightweight Systems and helds a professorship for Adaptive Systems at the Technical University of Braunschweig. He combines his experience from 15 years in the aviation industry with his research expertise in the field of lightweight system design, a combination of lightweight composite structures and function integration. Martin Wiedemann is board member in the Cluster of Excellence "Sustainable and Energy Efficient Aviation - SE2A" at the Technical University of Braunschweig and board member in the German wind energy research association. He is co-leader of the DLR Alliance for Lightweight Production Technologies and member of the German CFRP Fuselage Forum, a DLR cooperation with Airbus.

This book details science of hypersonics especially focusing on propulsion aspects such as supersonic combustion ramjets and their applications, and also includes lift and drag in hypersonic flight and their mathematical and physical explanation. It provides charts and data from hypersonic testing and measurements from actual vehicles and engines built in the past. Criteria to dimension hypersonic powered and unpowered vehicles (gliders) based on fundamental fluid dynamics and backed by flight testing; criteria to preliminary sizing vehicles and preliminary dimensioning of supersonic combustors are introduced. The book will serve better theoretical understanding of drag, lift and how to apply them to the design of hypersonic vehicles, as well as data to size vehicles and supersonic combustion ramjet (SCRJ) systems. This book will be a useful reference for researchers and designers in hypersonic vehicles but also second or third-year graduate students.

Fatigue occurs under cyclic loading and can significantly degrade the operational capability and safety of metallic aircraft components and structures. This book provides summaries of some metallic aircraft structural integrity issues, innovative but established examples of maintaining operational capability—airworthiness, and assessments of safe in-service fatigue lives. These topics are based on a through-life fatigue management philosophy that ensures safe and continued operation, including during life extensions that are almost inevitably required. This philosophy is underpinned by observations of the behaviour of fatigue cracks in actual structures subjected to realistic service loading conditions. The book includes topics like aircraft design requirements, individual aircraft fatigue loads monitoring, airframe fatigue testing, sources of fatigue-nucleating discontinuities, and prediction of fatigue crack growth from these discontinuities. All these aspects contribute to discussing methods of assuring the structural integrity and operational capability of realistically cracked structures. The book also discusses the exponential behaviour of lead or dominant cracks—those leading to first failure—and the practical significance of differences between fatigue fracture topographies produced under constant amplitude and variable amplitude loading. The book can be a valuable reference for researchers and professionals interested in aircraft fatigue management and allied fields.

This book is a useful source of knowledge for engineers and scientists in the field of mechanics of deformation and destruction of composite materials. In Chapter 1 three-dimensional equations of elasticity theory composed for the case of finite displacements and deformations of solids have been analyzed. It is found that the generally accepted simplifications known in the literature and carried out for the case of small deformations result in equations that are considered to be absolutely correct and consistent in all scientific and educational literature on mechanics of deformable solid bodies. However, this conclusion is not sufficiently well-founded as confirmed by formulation and solution of problems on the basis of generally accepted equations for determining both the stress-strain state (SSS) and the critical loads and buckling modes. In Chapter 2 the theoretical and experimental methods for determining the mechanical characteristics of fiber-reinforced plastics (FRPs) based on tensile and compression tests of flat specimens with [0]s , [±90]s, and [±45]2s lay-ups are analyzed. For FRPs with [±45]2s lay-ups, relations are derived for determining the components of lamina strains and stresses in the orthotropy axes of FRP monolayer in terms of axial strains and Poisson ratios of specimens measured in experiments. In Chapter 3 the structure of a unidirectional fibre composite of two types ELUR-P carbon fibre based on KhT-118 cold-curing binder and HSE 180 REM prepreg based on hot-curing binder has been studied. The diameters of fibres and fibre bundles (filaments) of both types of composites have been measured. Based on the results of the analysis of the composite material structure, a refined formulation of the linearised problems of a refined statement of linearized problems on flat internal multiscale buckling modes of a rigid lamina with either fibers or a fiber bundle is presented taking into account their interaction with an epoxy matrix. In Chapter 4 for shells of a layered structure based on the Timoshenko’s model, taking into account the transverse compression used for each layer, two versions of two-dimensional equations are constructed that describe geometrically nonlinear deformation with arbitrary displacements and small deformations. The formulation of a linear problem on the initial (subcritical) stress-strain state of a test specimen from a unidirectional fibrous composite with the [900]s structure during tension-compression tests with shear is given. A numerical method for solving the formulated problem is developed, which is based on the reduction of the original problem to a system of integro-algebraic equations and the search for their numerical solution by the finite sum method. In Chapter 5 conclusions were done and directions for further research have been identified.

This book systematically investigates the Mars entry problem from the perspectives of deterministic optimization, uncertainty optimization, and guidance. Began with a detailed review of the robotic missions and human-scaled exploration plans to Mars, theories or concepts of optimal control, uncertainty quantification, robust optimization, model predictive control, sequential convex programming, and computational guidance are subsequently introduced. Correspondingly, this book presents a series of trajectory planning and guidance algorithms to improve the robustness, reliability, and safety of the Mars missions. Because the Mars entry problem is studied using advanced mathematics, including probability theory, optimization theory, and cybernetics, thus the book is primarily designed as a textbook for graduate students in aerospace engineering, aeronautics, and astronautics departments. Engineers and researchers may also use this book as a reference or tutorial to help with the modeling and simulation of the Mars entry problem due to its thorough simulations and analyses.
