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 1963 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The generality of the airframe transfer function factor approximation formulas presented in ASD TDR-279 is tested by applying them to three dif ferent aircraft. The equations of motion for the test cases are presented and the exact and approximat1actors have been tabulated. The approximation formulas are then utilized to cal culate the sensitivity of the flexible airframe transfer function factors to mode shape. The formulas are given in terms of airplane stability derivatives which in turn are functions of the elastic mode deflections. Then, using the re sults of ASD-TDR-62-279, the desired sensitivity is readily calculable. Many of the transfer function factors are shown to be relatively in sensitive to mode shape, thus allowing effective approximation. A review of the literature per taining to approximate methods for calculating elastic mode shapes is presented in the form of an annotated bibliography. (Author).

This book was released on 1963 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flexible airframe equations of motion are derived with an arbitrary number of elastic de grees of freedom included. The number of equa tions is reduced to include only those necessary for adequate dynammic representation of the air frame, and the effects of the excluded modes are shown. The result is that a matrix X sub in finity must be calculated which is a function of the flexibility represented by the excluded modes. The calculation of this matrix is com plicated by the fact that it is, in explicit form, a function of the mode shapes for the ex cluded elastic degrees of freedom. Usually only a few of these higher order mode shapes can be found withh any accuracy. The problem is resolved by identifying two quantities, X sub f and X sub f infinity, which are ssuperposable to give the complete effects of structural static deflections, X sub infinity. This physi cally satisfying result is implemented by re lating X sub f infinity and X sub f to basic geometrical, inertial, and stiffness properties. The solution is completely general and applies to all elastic systems. (Author).
Book Synopsis Analytical Study of Approximate Longitudinal Transfer Functions for a Flexible Airframe by : B. F. Pearce

This book was released on 1962 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastic-airframe dynamics, important from the standpoint of flight control system design were studied. Approximate transfer functions are given in literal terms for three classes of vehicles. These are of such a form that th important poles and zeros are related directly to simple functions of aerodynamic, elastic, and inertial properties. The aeroelastic corrections required to account for the flexibility influences of all modes not included in the equations of motions are discussed, and a rigorous method for applying these corrections is presented.
