摘要

Aeroelastic analysis of lifting surface involvesrnsolving fluid and structural equations together.rnSuch coupling procedure need an advancedrncomputational structure mechanics for therndevelopment of structural model and advancedrncomputational fluid dynamics for the solution ofrnaerodynamics flow model. NASTRAN, a wellrnknown computer code for structural analysis, hasrnan advanced structural modeling, but does notrnhas the capability for solving aerodynamicallyrnnonlinear problems, such as aeroelasticity inrntransonic flow regimes.rnA computationally efficient technique for thernprediction of aerodynamic lift redistribution onrnflexible wing structure in transonic flow field isrnpresented in this paper. The advance capability inrnstructural modelling of finite element basedrnsoftware module is integrated with a newlyrndeveloped NTRANS, unsteady transonicrnaerodynamic software module. This integration isrncarried out through a quasi - steady coupling ofrnthe aerodynamic generalized forces with thernelastic structural deformation. This integrationrntechnique has been validated for clean wingrnconfiguration. Comparison of numerical resultsrnwith results obtained using other numericalrntechnique proves that this technique is accuraternand efficient for routine application.
