Aero engine manufacturers now use large, three dimensional, non-axisymmetric detailed finite element models of complete engines as a regular production design tool to evaluate the static and dynamic structural characteristics of new design. These have replaced the simpler beam type models for which techniques and criteria for evaluating engine dynamics had evolved over many years. The new tools produce an order of magnitude more information that is of better quality, but much more complicateddoi:10.1115/85-gt-230 fatcat:zg77ddjdy5h6lmpdii6c37abzy
