This book was released on 2018-07-02 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrated trajectory/control analysis algorithm has been used to generate trajectories and desired control strategies for two different hypersonic air-breathing vehicle models and orbit targets. Both models used cubic spline curve fit tabulated winged-cone accelerator vehicle representations. Near-fuel-optimal, horizontal takeoff trajectories, imposing a dynamic pressure limit of 1000 psf, were developed. The first model analysis case involved a polar orbit and included the dynamic effects of using elevons to maintain longitudinal trim. Analysis results indicated problems with the adequacy of the propulsion model and highlighted dynamic pressure/altitude instabilities when using vehicle angle of attack as a control variable. Also, the magnitude of computed elevon deflections to maintain trim suggested a need for alternative pitch moment management strategies. The second analysis case was reformulated to use vehicle pitch attitude relative to the local vertical as the control variable. A new, more realistic, air-breathing propulsion model was incorporated. Pitch trim calculations were dropped and an equatorial orbit was specified. Changes in flight characteristics due to the new propulsion model have been identified. Flight regimes demanding rapid attitude changes have been noted. Also, some issues that would affect design of closed-loop controllers were ascertained. Hattis, Philip D. and Malchow, Harvey L.

Book excerpt: This study was undertaken in response to a request by the U.S. Air Force that the National Research Council (NRC) examine whether the technologies that underlie the concept of a hypersonic, air-launched, air-breathing, hydrocarbon-fueled missile with speeds up to Mach 81 can be demonstrated in time to be initially operational by 2015. To conduct the study, the NRC appointed the Committee on Review and Evaluation of the Air Force Hypersonic Technology Program, under the auspices of the Air Force Science and Technology Board.
Download or read book Adaptive Dynamic Programming Single and Multiple Controllers written by Ruizhuo Song and published by Springer. This book was released on 2018-12-28 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a class of novel optimal control methods and games schemes based on adaptive dynamic programming techniques. For systems with one control input, the ADP-based optimal control is designed for different objectives, while for systems with multi-players, the optimal control inputs are proposed based on games. In order to verify the effectiveness of the proposed methods, the book analyzes the properties of the adaptive dynamic programming methods, including convergence of the iterative value functions and the stability of the system under the iterative control laws. Further, to substantiate the mathematical analysis, it presents various application examples, which provide reference to real-world practices.

This book was released on 2006-04-09 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense is developing the means to transform the nation's armed forces to meet future military challenges. For the Navy and Marine Corps, this vision is encompassed in Naval Power 21. Many new war-fighting concepts will be needed to implement this vision, and the ONR has requested the NRC to identify new science and technology opportunities for new naval aviation capabilities to support those concepts. This report presents an assessment of what they imply for naval aviation, an analysis of some capabilities that, if developed, would make a significant contribution to realizing those concepts, and an identification of key technologies in which ONR could invest to achieve those capabilities. In particular, the report focuses on seven key capabilities: multispectral defense, unmanned air operations, hypersonic weapons delivery, fast-kill weapons, heavy-lift air transport, intelligent combat information management, and omniscient intelligence.
