Numerical Simulations on Unsteady Nonlinear Transonic Airfoil Flow
Aerospace, 2020 Large-amplitude excitations need to be considered for gust load analyses of transport aircraft in cruise flight conditions. Nonlinear amplitude effects in transonic flow are, however, only marginally taken into account.

, 2012 This chapter deals with the basic principles of aeroelasticity theory (Theodorsen theory) and how these can be applied to bridge structures with sensitive deck shapes. The most common aerodynamical models with two or three forces as well as buffeting forces are briefly presented.

Aeroelasticity Model for Highly Flexible Aircraft Based on the Vortex Lattice Method
Aerospace, 2023 With the increasing use of composite materials in aviation, structural aircraft design often becomes limited by stiffness, rather than strength. As a consequence, aeroelastic analysis becomes more important to optimize both aircraft structures and ...

Effects of Aeroelastic Walls on the Aeroacoustics in Transonic Cavity Flow
Aerospace, 2022 The effects of elastic cavity walls on noise generation at transonic speed are investigated for the generic M219 cavity. The flow is simulated with the Spalart–Allmaras (SA) improved delayed detached-eddy simulation (IDDES) turbulence model in ...

Time-domain harmonic balance method for aerodynamic and aeroelastic simulations of turbomachinery flows [PDF]
, 2013 A time-domain Harmonic Balance method is applied to simulate the blade row interactions and vibrations of state- of-the-art industrial turbomachinery configurations. The present harmonic balance approach is a time-integration scheme that turns a periodic

Evolution Semigroups in Supersonic Flow-Plate Interactions [PDF]
, 2012 We consider the well-posedness of a model for a flow-structure interaction. This model describes the dynamics of an elastic flexible plate with clamped boundary conditions immersed in a supersonic flow.
