This book was released on 2018-07-17 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential of Hybrid Phase Stabilization (HPS), particularly for highly unstable aircraft, using a hypersonic flight vehicle (HSV) as a relevant example, is discussed. The development of HPS is presented and the result is compared with that generated using a conventional gain stabilization technique. Since HPS was not addressed in the MIL-spec requirements, a preliminary residual response metric was developed to provide guidance in assessing HPS.

This book was released on 2018-07-17 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced high performance vehicles, including Single-Stage-To-Orbit (SSTO) hypersonic flight vehicles, that are statically unstable, require higher bandwidth flight control systems to compensate for the instability resulting in interactions between the flight control system, the engine/propulsion dynamics, and the low frequency structural modes. Military specifications, such as MIL-F-9490D and MIL-F-87242, tend to limit treatment of structural modes to conventional gain stabilization techniques. The conventional gain stabilization techniques, however, introduce low frequency effective time delays which can be troublesome from a flying qualities standpoint. These time delays can be alleviated by appropriate blending of gain and phase stabilization techniques (referred to as Hybrid Phase Stabilization or HPS) for the low frequency structural modes. The potential of using HPS for compensating structural mode interaction was previously explored. It was shown that effective time delay was significantly reduced with the use of HPS; however, the HPS design was seen to have greater residual response than a conventional gain stablized design. Additional work performed to advance and refine the HPS design procedure, to further develop residual response metrics as a basis for alternative structural stability specifications, and to develop strategies for validating HPS design and specification concepts in manned simulation is presented. Stabilization design sensitivity to structural uncertainties and aircraft-centered requirements are also assessed.

This book was released on 2020-11-07 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest researches on hypersonic steady glide dynamics and guidance, including the concept of steady glide reentry trajectory and the stability of its regular perturbation solutions, trajectory damping control technique for hypersonic glide reentry, singular perturbation guidance of hypersonic glide reentry, trajectory optimization based on steady glide, linear pseudospectral generalized nominal effort miss distance guidance, analytical entry guidance and trajectory-shaping guidance with final speed and load factor constraints. They can be used to solve many new difficult problems in entry guidance. And many practical engineering cases are provided for the readers for better understanding. Researchers and students in the fields of flight vehicle design or flight dynamics, guidance and control could use the book as valuable reference.

Download or read book Principles and Practice of Aviation Psychology written by Pamela S. Tsang and published by CRC Press. This book was released on 2002-08-01 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering field history and discussing actual modern-day pilot actions and tasks, the editors of this volume have integrated contributions from leaders in aviation to present psychological principles and research pertinent to the interface between a pilot and the cockpit. The book addresses the pilot‘s cognitive demands, capabilities, and limitations, which have important implications for operator selection and training as well as display/control designs in the cockpit. It emphasizes scientific methods of achieving this understanding and implies that theories and principles of human behavior are shaped and improved by practical problems and applied studies.
