13. A study on correction methods for aeroelastic analysis in transonic flow.
The work presents a study of correction techniques to compute unsteady transonic pressure distributions and aeroelastic stability in this flow regime. The methodologies herein investigated are based on corrections of pressure distributions by the weighting of the lifting surface self-induced downwash, resulting from aeroelastic structural displacements or pr

14. Numerical model for the simulation of the aeroelastic response of fixed wings. / Modelo numérico para simulação da resposta aeroelástica de asas fixas.
A numerical model for the simulation of the aeroelastic response of fixed wings is proposed. The methodology used in the work is to treat the aerodynamic and the structural dynamics separately and then couple them in the equation of motion. The dynamic characterization of a prototype wing is done by the finite element method and the equation of motion is wri

15. Identificação modal de uma estrutura aeronáutica via algoritmo de realização de sistemas / Modal identification of an aeronautical structure via the eigensystem realization algorithm
The determination of the dynamic characteristics of aircraft structures has become an extremely important issue in the aerospace industry, primarily due to the continuous demand for lighter and consequently more flexible structures. In this context, most aerospace structural system must be subjected to some form of modal verification prior to flight in order
