Advanced Control of Flight Vehicle Maneuver and Operation
This book focuses on the advanced controller designs of flight vehicle maneuver and operation. Chapters explain advanced control mechanisms and algorithms for different controllers required in a flight vehicle system. The book topics such as air-disturbance fixed time controllers algorithms for orbit and attitude computation adaptive control modes altitude stabilization nonlinear vibration control partial space elevator configuration controls for formation flying and satellite cluster respectively.
Key features:
1) Includes an investigation of high-precision and high-stability control problems of flight vehicles
2) Multiple complex disturbances are considered to improve robust performance and control accuracy
3)Covers a variety of single spacecraft and distributed space systems (including hypersonic vehicles flexible aircraft rigid aircraft and satellites)
This book will be helpful to aerospace scientists and engineers who are interested in working on the development of flight vehicle maneuver and operation. Researchers studying control science and engineering and advanced undergraduate and graduate students and professionals involved in the flight vehicle control field will also benefit from the information given in this book.
Conceptual Design of Green Transport Airplane
Conceptual Design of Green Transport Airplanes presents key information methodologies and modern tools for the conceptual design of airliners that comply with requirements to minimal environmental impact. The book is comprised of eight chapters that address relevant subjects such as airplane technological evolution feasibility studies design framework for conceptual design and flight operations. Important issues and methods for an in-depth feasibility study are presented to facilitate the decision-making process of aircraft programs. These include examples of business plans for a 50-seat and 78-seat regional jets description of design phases market strategy competition among manufacturers regulatory requirements and technology assessment.
Readers will also be introduced to modern methodologies used in the conceptual design process of transport airplanes such as configuration study aerodynamics flight stability and control performance certification requirements and the role of flight operations. Thus the design process is explained in an integrated manner which paves the way towards a better understanding of an optimized aeronautical design environment where noise and emission constraints are taken into consideration.
Conceptual Design of Green Transport Airplanes is an essential reference work for aeronautical engineering students and technicians as well as industry professionals involved in the aviation and environmental protection/regulation industry.
High Order Large Eddy Simulation for Shock-Boundary Layer Interaction Control by a Micro-ramp Vortex Generator
This volume presents an implicitly implemented large eddy simulation (ILES) by using the fifth order bandwidth-optimized WENO scheme. The chosen method is applied to make comprehensive studies on ramp flows with and without control at Mach 2.5 and Re=5760. Flow control in the form of microramp vortex generators (MVG) is applied. The results show that a MVG can distinctly reduce the separation zone at the ramp corner and lower the boundary layer shape factor under simulated conditions. A series of new findings about the MVG-ramp flow are obtained including structures relevant to surface pressure three-dimensional structures of the re-compression shock waves a complete surface separation pattern momentum deficit and a new secondary vortex system.
A new mechanism of shock-boundary layer interaction control by MVG associated with a series of vortex rings is also presented. Vortex rings strongly interact with air flow and play an important role in the separation zone reduction. Additionally readers will learn about the governing equation boundary condition high quality grid generation high order shock capturing scheme and DNS inflow condition in detail. This volume will therefore serve as a useful reference for aerospace researchers using LES methods to study shock boundary layer interaction and supersonic flow control.
