Computational Fluid Dynamics/Computational Structural Dynamics Interaction Methodology for Aircraft Wings
With advanced subsonic transports and military aircraft operating in the transonic regime, it is becoming important to determine the effects of the coupling between aerodynamic loads and elastic forces. Because aeroelastic effects can signi cantly impact the design of these aircraft, there is a strong need in the aerospace industry to predict these interactions computationally.Such an analysis...
متن کاملStatic and Dynamic Aeroelastic Analysis of a High Aspect Ratio Wing through CFD-CSD Coupled Method
The Solar powered unmanned aircraft have a high-aspect-ratio wings because SPUAV must satisfy the requirement of long endurance and high lift-drag ratio. Therefore, the structure of SPUAV‘s wings are structurally very flexible. The very high flexible wing might have large deformation and many aeroelastic problems. In this paper have a static/dynamic aeroelastic analysis through CFD-CSD coupled ...
متن کاملFlapping Wing CFD/CSD Aeroelastic Formulation Based on a Co-rotational Shell Finite Element
Flexible flapping wings have garnered a large amount of attention within the micro aerial vehicle (MAV) community: a critical component of MAV flight is the coupling of aerodynamics and structural dynamics. This paper presents a computational framework for simulating shell-like wing structures flapping in incompressible flow at low Reynolds numbers in both hover and forward flight. The framewor...
متن کاملRotor Airloads Prediction Using Loose Aerodynamic/structural Coupling
This work couples a computational fluid dynamics (CFD) code and rotorcraft computational structural dynamics (CSD) code to calculate helicopter rotor airloads across a range of flight conditions. An iterative loose (weak) coupling methodology is used to couple the CFD and CSD codes on a per revolution, periodic basis. The CFD uses a high fidelity, Navier-Stokes, overset grid methodology with fi...
متن کاملA Computational Domain Decomposition Approach for Solving Coupled Flow-structure-thermal Interaction Problems
Solving complex coupled processes involving fluid-structure-thermal interactions is a challenging problem in computational sciences and engineering. Currently there exist numerous public-domain and commercial codes available in the area of Computational Fluid Dynamics (CFD), Computational Structural Dynamics (CSD) and Computational Thermodynamics (CTD). Different groups specializing in modellin...
