Available in PDF, EPUB and Kindle. Book excerpt: A six-degree-of-freedom, nonlinear dynamic derivative sensitivity study has been conducted on a fighter/bomber and an attack-type aircraft. The dynamic derivatives investigated in the study were C sub lq, C sub mq, C sub mp, C sub mr, C sub l beta, and C sub n beta. For the cross-coupling derivatives, C sub lq was shown to have the most significant effect on the level and 3-g turning flight motion, followed by C sub nq and C sub mp with the derivative C sub mr showing little to negligible effect in the same regime. For the acceleration derivatives, C sub l beta was shown to have a significant influence on the aircraft motion. The C sub n beta derivative had little effect on the simulated motion. The analysis also documents the configuration dependency of the cross-coupling derivatives and investigates the effects of nonlinear variations in the derivatives on the aircraft motion. (Author).

The effects of various dynamic derivatives on missile stability were investigated in both level and turning flight for several Mach numbers and altitude conditions.
Download or read book Aircraft Dynamic Stability and Response written by A. W. Babister and published by Elsevier. This book was released on 2013-10-22 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft Dynamic Stability and Response deals with the fundamentals of dynamic stability in aircraft. Topics covered include flight dynamics, equations of motion, and lateral and longitudinal aerodynamic derivatives. Basic lateral and longitudinal motions are also considered. A non-dimensional system of notation is used, and problems are included at the end of chapters. This book is comprised of 13 chapters and begins with an introduction to aircraft static stability and maneuverability, with emphasis on the theoretical basis of flight dynamics and the technical terms used. The physical background for the estimation of aerodynamic derivatives is discussed. Subsequent chapters focus on the longitudinal and lateral motion of aircraft, including the effect of automatic control; modern developments such as the effects of aeroelasticity, dynamic coupling, and high incidence; and aircraft response to gusts. The final chapter demonstrates how to estimate the aerodynamic derivatives, and hence the dynamic stability characteristics, of a typical fighter aircraft. Throughout the text, the aircraft and its behavior are kept well to the fore. This monograph is intended for undergraduate students of aeronautical engineering and for newcomers to the aircraft industry.

Download or read book Topics on Flexible Airplane Dynamics The application of flexible airframe transfer function approximations and the sensitivity of airframe transfer functions to elastic mode shapes written by and published by . This book was released on 1963 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: pt.3: The dynamic coupling of rigid and elastic degrees of freedom of an airplane are described by two methods. In the first, coupling is described by the changes in airframe characteristic equation roots caused by the introduction of coupling terms to the equations of motion. The second method employs modal response coefficients to compare the relative amplitudes of rigid and elastic degrees of freedom at each coupled mode frequency. Simple literal expressions are obtained for each of these descriptors and physical interpretations given. Time vector diagrams are also used to show the major parameters affecting coupling. (Author).

This book was released on 1972 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: A set of longitudinal stability derivatives for elastic airplanes is defined from fundamental principles allowing perturbations in forward speed. Application of these derivatives to longitudinal stability analysis by use of approximate expressions for static stability and control parameters as well as the dynamic equations of motion is illustrated. One commonly used alternative formulation for elastic airplanes is shown to yield significant inaccuracies because of inappropriate interpretation of inertial effects.
