Book Description
Aerodynamic lift is used during re-entry to provide range maneuverability so that a precise site can be selected and a horizontal landing capability can be provided. Maximum maneuverability may be achieved by modulating the hypersonic lift-to drag ratio (L/D). In this study the lifting re entry configuration was optimized to maximize hypersonic L/D within the heating, stability, and landing constraints. Eleven pertinent constraint equations were formulated, and numerical calcula tions of the complete aerodynamic characteristics and configurational geometry were determined. The IBM 7090 computer was used to solve the 11 constraint equations through an iteration tech nique and to perform the maximization process. Optimum configurational geometries were evaluated for three wing loadings at vehicle weights of 10,000 and 100,000 pounds. Results show that higher L/D values can be achieved with low aspect ratio, low wing loadings, and large scale vehi cles. The complete geometry for one of the typical optimums is shown as an example.

Book Description
This book covers the parameterization of entry capsules, including Apollo capsules and planetary probes, and winged entry vehicles such as the Space Shuttle and lifting bodies. The aerodynamic modelling is based on a variety of panel methods that take shadowing into account, and it has been validated with flight and wind tunnel data of Apollo and the Space Shuttle. The shape optimization is combined with constrained trajectory analysis, and the multi-objective approach provides the engineer with a Pareto front of optimal shapes. The method detailed in Conceptual Shape Optimization of Entry Vehicles is straightforward, and the output gives the engineer insight in the effect of shape variations on trajectory performance. All applied models and algorithms used are explained in detail, allowing for reconstructing the design tool to the researcher’s requirements. Conceptual Shape Optimization of Entry Vehicles will be of interest to both researchers and graduate students in the field of aerospace engineering, and to practitioners within the aerospace industry.

Book Description
This book is devoted to the state-of-the-art in all aspects of fireworks algorithm (FWA), with particular emphasis on the efficient improved versions of FWA. It describes the most substantial theoretical analysis including basic principle and implementation of FWA and modeling and theoretical analysis of FWA. It covers exhaustively the key recent significant research into the improvements of FWA so far. In addition, the book describes a few advanced topics in the research of FWA, including multi-objective optimization (MOO), discrete FWA (DFWA) for combinatorial optimization, and GPU-based FWA for parallel implementation. In sequels, several successful applications of FWA on non-negative matrix factorization (NMF), text clustering, pattern recognition, and seismic inversion problem, and swarm robotics, are illustrated in details, which might shed new light on more real-world applications in future. Addressing a multidisciplinary topic, it will appeal to researchers and professionals in the areas of metahuristics, swarm intelligence, evolutionary computation, complex optimization solving, etc.

Book Description
Ballistic Missile and Space Technology, Volume IV: Re-Entry and Vehicle Design focuses on the advancements of processes, methodologies, and technologies involved in re-entry and vehicle design, including hypersonics, material structures, propulsion, and communications. The selection first offers information on the pyrolysis of plastics in a high vacuum arc image furnace and aerothermodynamic feasibility of graphite for hypersonic glide vehicles. Discussions focus on aerothermochemical behavior of graphite, transient heat conduction, equilibrium glide trajectory, and apparatus and pyrolysis procedure. The text then takes a look at an engineering analysis of the weights of ablating systems for manned reentry vehicles and trajectories of lifting bodies entering planetary atmospheres at shallow angles. The manuscript ponders on propulsive control of atmospheric entry lifting trajectories, re-entry engineering mechanics, and rocket casing behavior predicted by laboratory tests. Topics include description of testing program, full-scale casing results, camera design, theoretical correlation, approximate thrust vector optimization, and propellant weight estimation. The selection is a dependable reference for astronauts and researchers interested in re-entry and vehicle design.
