Abstract : This report discusses some aspects of the stability problems of a freeflying column subjected to axial thrusts. In an age of spacecrafts and missiles, the stability of unsupported flying structures is of great importance. First the brief history of the lateral stability of a column is reviewed, and then the basic characteristic features of the stability problem of a freefree column are described. The mathematical techniques developed to solve these problems depend on a particular problem considered. The most general case requires the solution of a nonselfadjoint differential equation/boundary condition system, which is homogeneous and with zero eigenvalues. Numerical procedures for such a system appear to work well, although theoretical proof of convergence is still lacking. Results of these procedures are discussed. Keywords: Finite element analysis; Rotation; Rocket models.
