The article presents fluid-structure interaction methodology for the static aeroelastic coupling of aerostructures. A CFD and a FEM solver are coupled and the aeroelastic solution is iterated in order to obtain the steady state condition of the aerostructure. A three dimensional panel method is used as the CFD solver and MSC.Nastran is used as the finite element solver. In order to investigate large deflection effects, which are common in flexible aerostructures such as high aspect ratio wings, panel solution is coupled with both geometrically linear and nonlinear solution sequences of Nastran. The article explains the coupling process of the aerodynamic panels and the structural finite element mesh in detail and emphasizes the significance of geometrically non-linear structural analysis in static aeroelastic analysis of flexible structures.

Static Aeroelastic calculations for a wing under large deformations
Atik, Hediye; Baran, Özgür Uğraş; Tüzün, Aydin (2012-01-01)
This paper presents a practical workflow on static aeroelastic problems with extreme deflections. The aim of this study is to achieve a fast, yet robust method to calculate the change of the aerodynamic parameters as well as to ensure structural integrity of a wing deforming under aerodynamic loads. To predict static aeroelastic behavior of a high aspect ratio wing, calculations are performed on very fine grids at a relatively large number of flight conditions. Fluid calculations are performed with FLUENT o...
Multinucleon transfer in Ni-58+Ni-60 and Ni-60+Ni-60 in a stochastic mean-field approach
Yilmaz, B.; Ayik, S.; Yılmaz, Osman; Umar, A. S. (2018-09-07)
The multinucleon exchange mechanism in Ni-58 + Ni-60 and Ni-60 + Ni-60 collisions is analyzed in the framework of the stochastic mean-field approach. The results of calculations are compared with the time-dependent random-phase approximation (TDRPA) calculations and the recent data of Ni-58 + Ni-60. A good description of the data and a relatively good agreement with the TDRPA calculations are found.
Hierarchical multitasking control of discrete event systems: Computation of projections and maximal permissiveness
Schmidt, Klaus Verner; Cury, José E.r. (null; 2010-12-01)
This paper extends previous results on the hierarchical and decentralized control of multitasking discrete event systems (MTDES). Colored observers, a generalization of the observer property, together with local control consistency, allow to derive sufficient conditions for synthesizing modular and hierarchical control that are both strongly nonblocking (SNB) and maximally permissive. A polynomial procedure to verify if a projection fulfills the above properties is proposed and in the case they fail for a g...
Bici, M. Oguz; Stefanoski, Nikolce; Akar, Gözde (2009-05-06)
In this paper, we propose a Multiple Description Coding (MDC) method for reliable transmission of compressed time consistent 3D dynamic meshes. It trades off reconstruction quality for error resilience to provide the best expected reconstruction of 3D mesh sequence at the decoder side. The method is based on partitioning the mesh vertices into two sets and encoding each set independently by a 3D dynamic mesh coder. The encoded independent bitstreams or so-called descriptions are transmitted independently. T...
Implementation Studies of Robot Swarm Navigation Using Potential Functions and Panel Methods
Merheb, Abdel-Razzak; GAZİ, VEYSEL; Sezer Uzol, Nilay (2016-10-01)
This paper presents a practical swarm navigation algorithm based on potential functions and properties of inviscid incompressible flows. Panel methods are used to solve the flow equations around complex shaped obstacles and to generate the flowlines, which provide collision-free paths to the goal position. Safe swarm navigation is achieved by following the generated streamlines. Potential functions are used to achieve and maintain group cohesion or a geometric formation during navigation. The algorithm is i...
