Author:Van Zyl, Louwrens HDate:Jun 2007This paper describes the extension of the DLM to account for effects that are critical to the modelling of T-tail flutter. The boundary condition is made more general to account for yaw/dihedral and sideslip/dihedral coupling and the calculation ...Read more
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
