Author:Van Zyl, Louwrens HDate:Jun 2011The flutter analysis of T-tail aircraft poses challenges that are unique to this configuration, including the fact that the unsteady air loads are dependent on the steady load distribution and static deformation of the aircraft. In particular, ...Read more
Author:Van Zyl, Louwrens H; Gledhill, Irvy MADate:Nov 2011A grid was generated with the base of the fin, i.e. the hinge line, on the axis of a cylindrical domain with a diameter of 2m. Due to the axial symmetry of the setup, rotation of the T-tail should not change the pressure distribution on the ...Read more
Author:Van Zyl, Louwrens HDate:Jul 1993The use of eigenvectors to assign eigenvalues to modes for the p-k formulation of the flutter equation is described. The procedure has the potential to overcome some of the problems of the determinant iteration procedure to solve the flutter ...Read more
Author:Meijer, M-C; Dala, LDate:Aug 2015An aeroelastic prediction framework in MATLAB with modularity in the quasi-steady aerodynamic methodology is developed. Local piston theory (LPT) is integrated with quasi-steady methods including shock-expansion theory and the Supersonic ...Read more
