Book Description
A flight flutter experiment at the National Aeronautics and Space Administration (NASA) Dryden Fight Research Center, Edwards, California, used an 18-inch half-span composite model called the Aerostructures Test Wing (ATW). The ATW was mounted on a centerline flight test fixture on the NASA F-15B and used distributed piezoelectric strain actuators for in-flight structural excitation. The main focus of this paper is to investigate the performance of the piezoelectric actuators and test their ability to excite the first-bending and first-torsion modes of the ATW on the ground and in-flight. On the ground, wing response resulting from piezoelectric and impact excitation was recorded and compared. The comparison shows less than a 1-percent difference in modal frequency and a 3-percent increase in damping.

Book Description
FLIGHT THEORY AND AERODYNAMICS GET A PILOT'S PERSPECTIVE ON FLIGHT AERODYNAMICS FROM THE MOST UP-TO-DATE EDITION OF A CLASSIC TEXT The newly revised Fourth Edition of Flight Theory and Aerodynamics delivers a pilot-oriented approach to flight aerodynamics without assuming an engineering background. The book connects the principles of aerodynamics and physics to their practical applications in a flight environment. With content that complies with FAA rules and regulations, readers will learn about atmosphere, altitude, airspeed, lift, drag, applications for jet and propeller aircraft, stability controls, takeoff, landing, and other maneuvers. The latest edition of Flight Theory and Aerodynamics takes the classic textbook first developed by Charles Dole and James Lewis in a more modern direction and includes learning objectives, real world vignettes, and key idea summaries in each chapter to aid in learning and retention. Readers will also benefit from the accompanying online materials, like a test bank, solutions manual, and FAA regulatory references. Updated graphics included throughout the book correlate to current government agency standards. The book also includes: A thorough introduction to basic concepts in physics and mechanics, aerodynamic terms and definitions, and the primary and secondary flight control systems of flown aircraft An exploration of atmosphere, altitude, and airspeed measurement, with an increased focus on practical applications Practical discussions of structures, airfoils, and aerodynamics, including flight control systems and their characteristics In-depth examinations of jet aircraft fundamentals, including material on aircraft weight, atmospheric conditions, and runway environments New step-by-step examples of how to apply math equations to real-world situations Perfect for students and instructors in aviation programs such as pilot programs, aviation management, and air traffic control, Flight Theory and Aerodynamics will also appeal to professional pilots, dispatchers, mechanics, and aviation managers seeking a one-stop resource explaining the aerodynamics of flight from the pilot's perspective.

Book Description
Organised and written as an accessible study guide for student pilots wishing to take commercial ground examinations to obtain ATPL or CPL licenses, Principles of Flight for Pilots also provides a reliable up-to-date reference for qualified and experienced personnel wishing to further improve their understanding of the Principles of Flight and related subjects. Providing a unique aerodynamics reference tool, unlike any book previously Principles of Flight for Pilots explains in significant depth all the topics necessary to pass the Principles of Flight examination as required by the EASA syllabus. Aviation ground instructor Peter J. Swatton, well reputed for his previous works in the field of pilot ground training, presents the subject in seven parts including basic aerodynamics; level flight aerodynamics; stability; manoeuvre aerodynamics; and other aerodynamic considerations. Each chapter includes self-assessed questions, 848 in total spread over eighteen chapters, with solutions provided at the end of the book containing full calculations and explanations.

Book Description
Annotation Bridging the gap between academic research and real-world applications, this reference on modern flight control methods for fixed-wing aircraft deals with fundamentals of flight control systems design, then concentrates on applications based on the modern control methods used in the latest aircraft. The book is written for practicing engineers who are new to the aviation industry, postgraduate students in strategic or applied research, and advanced undergraduates. Some knowledge of classical control is assumed. Pratt is a member of IEEE and is UK Member for AIAA's Technical Committee on Guidance, Navigation and Control. Annotation c.

Book Description
Flight Dynamics, Simulation, and Control of Aircraft: For Rigid and Flexible Aircraft explains the basics of non-linear aircraft dynamics and the principles of control-configured aircraft design, as applied to rigid and flexible aircraft, drones, and unmanned aerial vehicles (UAVs). Addressing the details of dynamic modeling, simulation, and control in a selection of aircraft, the book explores key concepts associated with control-configured elastic aircraft. It also covers the conventional dynamics of rigid aircraft and examines the use of linear and non-linear model-based techniques and their applications to flight control. This second edition features a new chapter on the dynamics and control principles of drones and UAVs, aiding in the design of newer aircraft with a combination of propulsive and aerodynamic control surfaces. In addition, the book includes new sections, approximately 20 problems per chapter, examples, simulator exercises, and case studies to enhance and reinforce student understanding. The book is intended for senior undergraduate and graduate mechanical and aerospace engineering students taking Flight Dynamics and Flight Control courses. Instructors will be able to utilize an updated Solutions Manual and figure slides for their course.

Book Description
Introduction to Flight Testing Introduction to Flight Testing Provides an introduction to the basic flight testing methods employed on general aviation aircraft and unmanned aerial vehicles Introduction to Flight Testing provides a concise introduction to the basic flight testing methods employed on general aviation aircraft and unmanned aerial vehicles for courses in aeronautical engineering. There is particular emphasis on the use of modern on-board instruments and inexpensive, off-the-shelf portable devices that make flight testing accessible to nearly any student. This text presents a clear articulation of standard methods for measuring aircraft performance characteristics. Topics covered include aircraft and instruments, digital data acquisition techniques, flight test planning, the standard atmosphere, uncertainty analysis, level flight performance, airspeed calibration, stall, climb and glide, take-off and landing, level turn, static and dynamic longitudinal stability, lateral-directional stability, and flight testing of unmanned aircraft systems. Unique to this book is a detailed discussion of digital data acquisition (DAQ) techniques, which are an integral part of modern flight test programs. This treatment includes discussion of the analog-to-digital conversion, sample rate, aliasing, and filtering. These critical details provide the flight test engineer with the insight needed to understand the capabilities and limitations of digital DAQ. Key features: Provides an introduction to the basic flight testing methods and instrumentation employed on general aviation aircraft and unmanned aerial vehicles. Includes examples of flight testing on general aviation aircraft such as Cirrus, Diamond, and Cessna aircraft, along with unmanned aircraft vehicles. Suitable for courses on Aircraft Flight Test Engineering. Introduction to Flight Testing provides resources and guidance for practitioners in the rapidly-developing field of drone performance flight test and the general aviation flight test community.
