Flight loads are the main factor that defines strength of the airplane units. In common case, trim parameters and maneuvering loads (for static aeroelasticity) within MSC.Nastran are evaluated by doublet lattice method. Flat aerodynamics approach influences on the computational accuracy. The goal of the research is improvement of the problem using three-dimensional aerodynamic data obtained from computational fluid dynamics. The passenger airplane as an example is considered. The distribution of aerodynamic forces on wetted surfaces is computed within Fluent. Using MSC.Nastran Hybrid Static Aeroelasticity Toolkit, these three-dimensional aerodynamic mesh and aerodynamic forces at the nodes are imported in the design model. Analysis of trim parameters and flight loads in MSC.Nastran is performed.
