1. Unsteady aerodynamic coefficients obtained by a compressible vortex lattice method.
Unsteady solutions for the aerodynamic coefficients of a thin airfoil in compressible subsonic or supersonic flows are studied. The lift, the pitch moment, and pressure coefficients are obtained numerically for the following motions: the indicial response (unit step function) of the airfoil, i.e., a sudden change in the angle of attack; a thin airfoil penetr

2. Further developments in unsteady compressible vortex lattice method in two dimensional motion.
Unsteady phenomena like flutter, buffeting, rapid maneuvers in flight and gust entry are usually modeled and studied by a theoretical treatment involving potential flow methods. The resulting equation from this approach is the governing differential equation for general non-steady, non-viscous, potential flow known as convected wave equation. The disturbance

3. Numerical model for the simulation of fixed wings aeroelastic response
A numerical model for the simulation of fixed wings aeroelastic response is presented. The methodology used in the work is to treat the aerodynamics and the structural dynamics separately and then couple them in the equations of motion. The dynamic characterization of the wing structure is done by the finite element method and the equations of motion are wri

4. 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

5. Processos de magnetização em supercondutores do tipo II : um estudo em monocristal de ErBaCuO com defeitos colunares
We present in this work a study of the magnetization and vortex lattice behavior, when a superconducting ErBa2CU3O7-d single crystal with columnar defects is rotated under a fixed magnetic field. We describe the procedures used in the development of BaZrO3 crucibles, and in the growth of YBa2CU3O7-d and ErBa2CU3O7-d single crystals using this crucible and al

6. Modelo de interferência aerodinâmica entre jato e empenagem
Neste trabalho apresenta-se uma metodologia para a estimativa dos efeitos de interferência aerodinâmica sobre empenagens devido a jatos turbulentos, subsônicos e aquecidos. Primeiramente emprega-se um método de diferenças finitas para resolver numericamente as equações de Reynolds com as aproximações de camada limite. As equações de reynolds são
