Flight Dynamics takes a new approach to the science and mathematics of aircraft flight, unifying principles of aeronautics with contemporary systems analysis. While presenting traditional material that is critical to understanding aircraft motions, it does so in the context of modern computational tools and multivariable methods. Robert Stengel devotes particular attention to models and techniques that are appropriate for analysis, simulation, evaluation of flying qualities, and control system design. He establishes bridges to classical analysis and results, and explores new territory that was treated only inferentially in earlier books. This book combines a highly accessible style of presentation with contents that will appeal to graduate students and to professionals already familiar with basic flight dynamics. Dynamic analysis has changed dramatically in recent decades, with the introduction of powerful personal computers and scientific programming languages. Analysis programs have become so pervasive that it can be assumed that all students and practicing engineers working on aircraft flight dynamics have access to them. Therefore, this book presents the principles, derivations, and equations of flight dynamics with frequent reference to MATLAB functions and examples. By using common notation and not assuming a strong background in aeronautics, Flight Dynamics will engage a wide variety of readers. Introductions to aerodynamics, propulsion, structures, flying qualities, flight control, and the atmospheric and gravitational environment accompany the development of the aircraft's dynamic equations.

An investigation was made in the Langley Unitary Plan wind tunnel to determine the behavior of paraglider models at moderate to high supersonic speeds. The models were deployed from a sting in the supersonic stream and steady-state aerodynamics performance data were obtained. Maximum values of the lift-drag ratio were about 1.4 at a Mach number of 2.65 and about 1.2 at a Mach number of 4.65. The angles of attack over which the models could be flown were limited by unsteady behavior of the canopy.

Radical Wings and Wind Tunnels presents a behind-the-scenes look at how the NACA, and today's NASA, have used wind tunnels and flight-testing in past and current projects to advance aeronautical science. NASA's Langley Research Center, located in Hampton, Virginia, was established on July 17, 1917, and has played a key role in the research and development of civil and military aviation since its infancy. For over 90 years, Langley's staff has wind-tunnel tested or test flown a wide range of leading-edge aircraft designs including vertical takeoff and landing aircraft, advanced fighters, civil transports, and high-speed supersonic and hypersonic vehicles. Results from the legacy of Langley's pioneering basic and applied aeronautical research have been incorporated into virtually all U.S. civil transports and military aircraft. This book describes the very unique testing capabilities of several historic Langley wind tunnels, such as the gigantic 30 x 60 ft Full Scale Tunnel, the Vertical Spin Tunnel, and the Free-Flight Tunnel. The major focus of the book is a discussion of the roles these wind tunnels and the NACA and NASA organizations played in R&D activities for more than 60 radical aerospace vehicles that did not, or have not yet entered production. The contents present an illuminating perspective on how the government's research agencies interacted beneficially with the military and civil communities for many of this nation's innovative aeronautical undertakings. Coverage begins in the 1920s with research on the earliest innovations for monoplanes and extends to current research on tomorrow's aircraft including hypersonic vehicles and aircraft designed to explore the Martian environment. Topics also include previously unpublished details of NACA activities in development of U.S. military aircraft in WWII, Langley's work on parawing vehicles, key activities for V/STOL aircraft, challenges for lifting bodies and reentry vehicles, ongoing research to remove the barriers for economically viable supersonic commercial transport, the latest technology for highly maneuverable fighters, and a look at the future. The photos in this edition are in black and white.

Exploratory static-stability tests were made on models of the MK-84 weapon and a modular weapon configuration during simulated weapon separation from the wing of the F-4C Tactical Fighter Aircraft at freestream Mach numbers 1.76, 2.0, and 2.5. Data were obtained with the parent aircraft at zero angle of attack and the weapon at the carriage incidence angle of -1 deg. Supplementary data were obtained for weapon angles of attack of + or - deg. Unit Reynolds number ranged from 4.6 million per ft at M free stream mach number = 1.76 to 6.2 million per ft at M free stream mach number = 2.5. Selected results are presented which show the effects on the weapon aerodynamic loads of free-stream Mach number, weapon angle of attack, weapon axial position, and the presence of other stores. Representative shadowgraph and schlieren photographs of the interference flow field are also presented. (Author).

A supersonic wind tunnel investigation was conducted in the NASA Langley Unitary Plan Wind Tunnel on an advanced derivative configuration of the United States Air Force F-16 fighter. Longitudinal and lateral directional force and moment data were obtained at Mach numbers of 1.60 to 2.16 to evaluate basic performance parameters and control effectiveness. The aerodynamic characteristics for the F-16 derivative model were compared with the data obtained for the F-16C model and also with a previously tested generic wing model that features an identical plan form shape and similar twist distribution.
