Book Description
The report (Volume II, Program User Guide) describes the computer program developed for the evaluation of the aerodynamic characteristics of large aircraft (bombers, tankers, and transports). The program calculates lift, moment, and drag characteristics of aircraft through the subsonic, transonic, and supersonic speed regimes, and includes the capability of calculating the effect of high-lift systems in both free air and in ground effect for landing and takeoff. The input to the computer program requires the configuration geometry and the aerodynamic conditions for which solutions are desired. The program includes the capability of analyzing both fixed-wing and variable-sweep- wing configurations as well as the aerodynamic characteristics of supercritical wing designs.

Book Description
The report presents the methods, equations, and substantiating data for an empirically based computer program for the rapid and accurate evaluation of the aerodynamic characteristics of large aircraft (bombers, tankers, and transports) from takeoff through landing and through the subsonic, transonic, and supersonic speed regimes. The program calculates lift, moment, and drag characteristics at both low- and high-lift conditions, including the effects of ground proximity during landing and takeoff. The input requires the configuration geometry and the aerodynamic conditions for which solutions are desired. The program includes the capability of analyzing both fixed-wing and variable-sweep-wing configurations as well as the aerodynamic characteristics of the most recent supercritical wing designs.

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.

Author: Aircraft Aerodynamic Parameter Estimation from Flight Data Using Neural Partial Differentiation
Author: Majeed MohamedPublisher: Springer Nature
ISBN: 9811601046
Category : Technology & Engineering
Languages : en
Pages : 66
Book Description
This book presents neural partial differentiation as an estimation algorithm for extracting aerodynamic derivatives from flight data. It discusses neural modeling of the aircraft system. The neural partial differentiation approach discussed in the book helps estimate parameters with their statistical information from the noisy data. Moreover, this method avoids the need for prior information about the aircraft model parameters. The objective of the book is to extend the use of the neural partial differentiation method to the multi-input multi-output aircraft system for the online estimation of aircraft parameters from an established neural model. This approach will be relevant for the design of an adaptive flight control system. The book also discusses the estimation of aerodynamic derivatives of rigid and flexible aircraft which are treated separately. The longitudinal and lateral-directional derivatives of aircraft are estimated from flight data. Besides the aerodynamic derivatives, mode shape parameters of flexible aircraft are also identified in the book as part of identification for the state space aircraft model. Since the detailed description of the approach is illustrated through the block diagram and their results are presented in tabular form with figures of parameters converge to their estimates, the contents of this book are intended for readers who want to pursue a postgraduate and doctoral degree in science and engineering. This book is useful for practicing scientists, engineers, and teachers in the field of aerospace engineering.
