Nonlinear Static Aeroelastic Behavior of Composite Missile Fin with Interlaminar and Intralaminar Damage

Kayran, Altan
Nonlinear static aeroelastic behavior of the damaged composite missile fins is investigated. For this purpose, two-way coupled fluid structure interaction (FSI) analyses are performed to study the effect of different failure modes on the static aeroelastic behaviour of composite missile fins.The FSI analysis is done with two separate solvers, ANSYS CFX for the fluid (CFD) and ANSYS Mechanical for the structure (FEM) which runs in sequential order and exchange information at the interface of the fluid and structure domains. The static aeroelastic behaviour of a composite missile fin is presented with induced interlaminar and intralaminar damages. For this purpose three-dimensional composite missile fin is modeled using ANSYS ACP tool and interlaminar and intralaminar damages are created in the composite missile fin. The effects of interlaminar and intralaminar damages on the static aeroelastic behaviour of the missile fin are investigated separately by considering them one at a time and together. Following the generation of different damages in the missile fin, two-way FSI analysis is performed to predict the effect of the damage modes on the pressure distribution, lift and deformation of the damaged fin and comparisons are made with the undamaged missile fin.

Özkaya, Özge; Kayran, Altan (2017-09-22)
Nonlinear static aeroelastic behavior of a basic composite missile fin is analyzed by means of two-way coupled FSI simulation and the effects of composite damages are presented. The configuration has been simulated by coupling the two commercial solvers ANSYS CFX for the fluid mechanical simulation with ANSYS Mechanical for the structural simulation. 3D composite fin geometry is constructed using ANSYS ACP tool. Interlaminar damage cases were investigated and the influence of the damage locations on the sta...
Static aeroelastic modeling and parametric study of stacking sequence for laminated composite missile fins
Aslan, Göktuğ Murat; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2018)
In this thesis, a surface-to-surface missile model with laminated composite fins is examined with respect to one-way static aeroelastic response under constant supersonic flight conditions. Two different modified double wedge fins or control surfaces using for control actuation system of a missile are investigated and compared in terms of aerodynamic and linear structural characteristics in order to minimize tip deflection. A serial set of steady-state supersonic Computational Fluid Dynamics (CFD) analyses ...
Numerical investigations of lateral jets for missile aerodynamics
Ağsarlıoğlu, Ekin; Albayrak, Kahraman; Department of Mechanical Engineering (2011)
In this thesis, effects of sonic lateral jets on aerodynamics of missiles and missilelike geometries are investigated numerically by commercial Computational Fluid Dynamics (CFD) software FLUENT. The study consists of two parts. In the first part, two generic missile-like geometries with lateral jets, of which experimental data are available in literature, are analyzed by the software for validation studies. As the result of this study, experimental data and CFD results are in good agreement with each other...
Numerical investigation of characteristics of pitch and roll damping coefficients for missile models
Kayabaşı, İskander; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2012)
In this thesis the characteristics of pitch and roll damping coefficients of missile models are investigated by using Computational Fluid Dynamics (CFD) techniques. Experimental data of NACA0012 airfoil, Basic Finner (BF) and Modified Basic Finner (MBF) models are used for validation and verification studies. Numerical computations are performed from subsonic to supersonic flow regimes. Grid refinement and turbulence model selection studies are conducted before starting the dynamic motion simulations. Numer...
Jet Shapes of Isolated Photon-Tagged Jets in Pb-Pb and pp Collisions at root S-NN=5.02 TeV
Sirunyan, A. M.; et. al. (2019-04-01)
The modification of jet shapes in Pb-Pb collisions, relative to those in pp collisions, is studied for jets associated with an isolated photon. The data were collected with the CMS detector at the LHC at a nucleon- nucleon center-of-mass energy of 5.02 TeV. Jet shapes are constructed from charged particles with track transverse momenta (p(T)) above 1 GeV/c in annuli around the axes of jets with p(T)(jet) > 30 GeV/c associated with an isolated photon with p(T)(gamma) > 60 GeV/c. The jet shape distributions a...
