Complex Notation in Flutter Analysis
Journal of Structural Engineering, 1999Flutter analysis in aircraft or bridge engineering has to include motion-induced aerodynamic forces. These forces are mathematically described in two equivalent ways, namely, by real number or complex number expressions. Accordingly, flutter analysis can be performed using either real or complex arithmetic.

Flutter Analysis of a Space Vehicle
Frontiers in Aerospace Engineering, 2014In general, flying vehicles which shear through air are subjected to various types of worst environmental loads. The components such as wing, vertical tail, booster fins were been heavily subjected to aerodynamic loads. As these components are designed for minimum weight configuration that results in very flexible structures, which leads to various ...

Flutter analysis of advanced turbopropellers
AIAA Journal, 1983The two-dimensional subsonic cascade unsteady aerodynamic theory of Jones and Rao (1975) has been modified to account for the variable sweep angles of the blades of advanced turbopropellers. The aerodynamics and the structural modal properties have been formally integrated to determine the generalized aerodynamic coefficients matrix for the blade modes.

41st Structures, Structural Dynamics, and Materials Conference and Exhibit, 2000
Flutter analysis performed in support of the X33 Advanced Technology Demonstrator is described. Analysis was conducted over a range of flow regimes using several different analysis codes. The finite element and aerodynamic models used in the analysis have undergone several years of development and refinement resulting in a high degree of model detail ...

The Analysis of Aerodynamic Flutter of Suspension Bridges
Civil-Comp Proceedings, 1988Abstract Suspension bridges are long slender flexible structures which have the potential to be susceptible to a variety of types of wind induced vibrations, the most serious of which is the aerodynamic instability known as flutter. In this phenomenon at certain windspeeds aerodynamic forces acting on the deck are of such a nature so as to feed ...

Nonlinear transonic flutter analysis
Dynamics Specialists Conference, 1981A numerical procedure is presented for predicting the static and dynamic aeroelastic characteristics of thin, clean swept wings in transonic flow. The method is based upon the simultaneous time integration of the equations governing the coupled nonlinear fluid dynamic and structural aeroelastic system.

An Approximate Analysis of Nonlinear Flutter Problems
Journal of the Aerospace Sciences, 1959The approximate analysis of nonlinear flutter problems by the method of KrylofT and BogoliubofT is outlined. The method is presented in a simple fashion based upon the concept of "harmonic balance." Because of the nature of the response of flutter systems to sinusoidal excitations of various frequencies, it appears that the method should be ...
