  • Van Zyl, LH (American Institute of Aeronautics and Astronautics, 1994-11)
    The article discusses ways in which the integrals resulting from a zero-order discontinuous pressure distribution can be arranged in such a way that they can be solved by either normal quadrature or curve fitting followed ...
  • Van Zyl, Lourens H (American Institute of Aeronautics and Astronautics, 2008-01)
    The calculation of unsteady air loads is an essential step in any aeroelastic analysis. The subsonic doublet lattice method (DLM) is used extensively for this purpose due to its simplicity and reliability. The body models ...
  • Van Zyl, Lourens H (American Institute of Aeronautics and Astronautics, 1993-07)
    The 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 ...
