Aircraft Control Allocation Wayne Durham, Virginia Polytechnic Institute and State University, USA Kenneth A. Bordignon, Embry-Riddle Aeronautical University, USA Roger Beck, Dynamic Concepts, Inc., USA An authoritative work on aircraft control allocation by its pioneers Aircraft Control Allocation addresses the problem of allocating supposed redundant flight controls. It provides introductory material on flight dynamics and control to provide the context, and then describes in detail the geometry of the problem. The book includes a large section on solution methods, including 'Banks' method', a previously unpublished procedure. Generalized inverses are also discussed at length. There is an introductory section on linear programming solutions, as well as an extensive and comprehensive appendix dedicated to linear programming formulations and solutions. Discrete-time, or frame-wise allocation, is presented, including rate-limiting, nonlinear data, and preferred solutions. Key features: Written by pioneers in the field of control allocation. Comprehensive explanation and discussion of the major control allocation solution methods. Extensive treatment of linear programming solutions to control allocation. A companion web site contains the code of a MATLAB/Simulink flight simulation with modules that incorporate all of the major solution methods. Includes examples based on actual aircraft. The book is a vital reference for researchers and practitioners working in aircraft control, as well as graduate students in aerospace engineering.

Aircraft Flight Dynamics and Control addresses airplane flight dynamics and control in a largely classical manner, but with references to modern treatment throughout. Classical feedback control methods are illustrated with relevant examples, and current trends in control are presented by introductions to dynamic inversion and control allocation. This book covers the physical and mathematical fundamentals of aircraft flight dynamics as well as more advanced theory enabling a better insight into nonlinear dynamics. This leads to a useful introduction to automatic flight control and stability augmentation systems with discussion of the theory behind their design, and the limitations of the systems. The author provides a rigorous development of theory and derivations and illustrates the equations of motion in both scalar and matrix notation. Key features: * Classical development and modern treatment of flight dynamics and control * Detailed and rigorous exposition and examples, with illustrations * Presentation of important trends in modern flight control systems * Accessible introduction to control allocation based on the author's seminal work in the field * Development of sensitivity analysis to determine the influential states in an airplane's response modes * End of chapter problems with solutions available on an accompanying website Written by an author with experience as an engineering test pilot as well as a university professor, Aircraft Flight Dynamics and Control provides the reader with a systematic development of the insights and tools necessary for further work in related fields of flight dynamics and control. It is an ideal course textbook and is also a valuable reference for many of the necessary basic formulations of the math and science underlying flight dynamics and control.

This monograph looks at the reasons to change the national military strategy to a win-hold-win strategy from the existing win-win Two-Major Regional Conflict (MRC) strategy, and then examines naval strategy and doctrine in the context of the required new mission of holding an aggressor in a second MRC. The monograph assesses the requirements to accomplish the holding mission in light of the ongoing revolution in military affairs, and ultimately seeks to address the contributions and limitations of naval forces in stopping and holding an aggressor in a second MRC. Current defense spending is below that required to both maintain the force structure to execute the two MRC strategy and modernize the force. Cuts in defense spending in support of balancing the U.S. budget, justified by the end of the Cold War and reduced threat, will result in a military force structure below that required to support the existing strategy. Moving to a win-hold-win strategy and smaller force structure will still allow the U.S. to maintain the capability to respond to two MRCs, although at increased risk from both a military and foreign policy perspective. Supporting a smaller force structure could free up the funds required to ensure force modernization. Naval forces bring a unique set of capabilities to a win-hold-win national military strategy, and can make a decisive contribution to the execution of the holding mission. The Navy white paper, From the Sea, committed the naval service to the Support of land forces through littoral operations, and the missions of forward presence, crisis response, and power projection ashore. The holding mission in a win-hold-win national military strategy is a logical extension of the enabling mission, and is entirely consistent with the concepts and direction of current naval strategy. It is reasonable to assume that forces designed for the enabling mission could be leveraged, within acceptable cost limts, to successfully carry out the holding mission.
