METHOD OF PERFORMING COMPUTATIONAL AEROELASTIC ANALYSES |
摘要 |
Computational aeroeiastic analyses typically use a mathematical model for the structural modes of a flexible structure and a nonlinear aerodynamic model that can generate a plurality of unsteady aerodynamic responses based on the structural modes for conditions defining an aerodynamic condition of the flexible structure. In the present invention, a linear state-space model is generated using a single execution of the nonlinear aerodynamic model for all of the structural modes where a family of orthogonal functions is used as the inputs. Then, static and dynamic aeroeiastic solutions are generated using computational interaction between the mathematical model and the linear state-space model for a plurality of periodic points in time. |
