An experimental evaluation of analytical techniques for predicting certain stability and control characteristics of a large flexible aircraft is presented. Analytical methods based on both the model approach and flexibility influence coefficients are developed to predict the aerodynamic characteristics of a flexible airplane. These methods are then applied to a flexibly scaled model of a supersonic transport configuration. Comparisons of wind-tunnel data, calculations based on the model approach, and flexibility influence coefficients are presented over the Mach number range from 0.6 to 2.7. An examination of the results obtained from this study indicates that both analytical techniques predict reasonably well the effect of flexibility on the basic longitudinal characteristics and that both techniques give generally comparable results.

"In this part, exhaustive coverage is provided of the methods for analysis and synthesis of automatic flight control systems using classical control theory. This widely used book has been updated with the latest software methods. Throughout this text, the practical (design) applications of the theory are stressed with many examples and illustrations. Aircraft stability and control characteristics are all heavily regulated by civil as well as by military airworthiness authorities for safety reasons. The role of the these safety regulations in the application of the theory is therefore stressed throughout. Airplane Flight Dynamics & Automatic Flight Controls, Part II, is an essential reference for all aeronautical engineers working in the area of stability and control, regardless of experience levels. The book minimizes reader confusion through a systematic progression of fundamentals: - Elastic airplane stability and control coefficients and derivatives - Method for determining the equilibrium and manufacturing shape of an elastic airplane - Subsonic and supersonic numerical examples of aeroelasticity effects on stability & control derivatives - Bode and root-locus plots with open and closed loop airplane applications, and coverage of inverse applications - Stability augmentation systems: pitch dampers, yaw dampers and roll dampers - Synthesis concepts of automatic flight control modes: control-stick steering, auto-pilot hold, speed control, navigation and automatic landing - Digital control systems using classical control theory applications with Z-transforms - Applications of classical control theory - Human pilot transfer functions." --DescripciĆ³n del editor.
