Book Description
The theory of functionals is used to reformulate the notions of aerodynamic indicial functions and superposition. Integral forms for the aerodynamic response to arbitrary motions are derived that are free of dependence on a linearity assumption. Simplifications of the integral forms lead to practicable nonlinear generalizations of the linear superposition and the stability derivative formulations. Applied to arbitrary nonplanar motions, the generalization yields a form for the aerodynamic response that can be compounded of the contributions from a limited number of well-defined characteristic motions, in principle reproducible in the wind tunnel. Further generalizations that would enable the consideration of random fluctuations and multivalued aerodynamic responses are indicated.

Book Description
Aeronautical engineers concerned with the analysis of aircraft dynamics and the synthesis of aircraft flight control systems will find an indispensable tool in this analytical treatment of the subject. Approaching these two fields with the conviction that an understanding of either one can illuminate the other, the authors have summarized selected, interconnected techniques that facilitate a high level of insight into the essence of complex systems problems. These techniques are suitable for establishing nominal system designs, for forecasting off-nominal problems, and for diagnosing the root causes of problems that almost inevitably occur in the design process. A complete and self-contained work, the text discusses the early history of aircraft dynamics and control, mathematical models of linear system elements, feedback system analysis, vehicle equations of motion, longitudinal and lateral dynamics, and elementary longitudinal and lateral feedback control. The discussion concludes with such topics as the system design process, inputs and system performance assessment, and multi-loop flight control systems. Originally published in 1974. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
This text offers an analytic description of the dynamic behavior of an aircraft in flight. The explanation firstly covers in detail the build up and characterization of an analytic model for aircraft in flight. The proposed derivation process allows the reader to obtain an in-depth knowledge of the principles and assumptions employed in the obtainment of the equations describing the dynamic response of an aircraft, in parallel yielding suggestions on how to easily obtain models for other flying machines. Secondly, the model representing aircraft dynamics is populated, employing as much as possible additional simple models, linking basic aerodynamic and geometrical characteristics of an aircraft to the corresponding re- presentation in terms of coefficients. Finally, the dynamic performance of a typical aircraft is analyzed, making use of the notions on the dynamic behavior and on the typical values and balance of aircraft-specific coefficients. In this latter part, following an analysis of a equilibrium conditions, static and dynamic stability qualities are analyzed. An introduction to the conditioning of free dynamics through the design of a stability augmentation system is included as well. This book aims to support engineers as well as engineering students at the graduate level, of- fering a concise yet in-depth description of the dynamic behavior of a flying aircraft, trying to keep a rigorous approach to a greater extent than what is usual in the field. This should hopefully foster the comprehension of the key features in the model derivation process, and consequently the range of validity and applicability of the corresponding formulation. This focus on analytic modeling provides the reader with a key-asset when dealing with engineering problems, for example flight simulation, model identification and flight control design. Therefore, the present books attempts to mark a first relevant step in consolidating the notions required to face more specialized topics in aeronautical engineering.

Book Description
The second edition of Flight Stability and Automatic Control presents an organized introduction to the useful and relevant topics necessary for a flight stability and controls course. Not only is this text presented at the appropriate mathematical level, it also features standard terminology and nomenclature, along with expanded coverage of classical control theory, autopilot designs, and modern control theory. Through the use of extensive examples, problems, and historical notes, author Robert Nelson develops a concise and vital text for aircraft flight stability and control or flight dynamics courses.
