Investigation of Aeroelasticity Effect on Missile Separation from the Internal Bay

open access: yesInternational Journal of Aerospace Engineering, 2023
There is a strong aerodynamic interference when launching the missile in the embedded mode. During the separation process, the carrier aircraft safety may be threatened due to large slenderness ratio, low structural stiffness, and aeroelasticity effects ...

NUMERICAL SIMULATION OF OSCILLATIONS OF A PLATE IN RESTING FLUID

open access: yesInternational Journal for Computational Civil and Structural Engineering, 2023
This paper presents a numerical solution of the problem of oscillations of a flexible plate placed in a viscous incompressible fluid done with ANSYS. In constructing a finite element model of the plate, both volumetric and shell finite elements, which ...

Measurement of FRFs and Modal Identification in Case of Correlated Multi-Point Excitation

open access: yesShock and Vibration, 2008
The modal identification of large and dynamically complex structures often requires a multi-point excitation. Sine sweep excitation runs are applied when it is necessary to concentrate more energy on each line of the frequency spectrum.

Eliminating flutter for clamped von Karman plates immersed in subsonic flows [PDF]

open access: yes, 2014
We address the long-time behavior of a non-rotational von Karman plate in an inviscid potential flow. The model arises in aeroelasticity and models the interaction between a thin, nonlinear panel and a flow of gas in which it is immersed [6, 21, 23 ...

Geometrical Nonlinear Aeroelastic Stability Analysis of a Composite High-Aspect-Ratio Wing

open access: yesShock and Vibration, 2008
A composite high-aspect-ratio wing of a high-altitude long-endurance (HALE) aircraft was modeled with FEM by MSC/NASTRAN, and the nonlinear static equilibrium state is calculated under design load with follower force effect, but without load ...
