Not many years ago, lifting-surface computations appeared to be too costly and difficult to carry out except for major propeller designs. Now such calculations can readily be performed on a personal computer. On the other hand, unsteady Navier-Stokes computations (with full turbulence modelling) cannot be expected to be carried out for propeller flows on any present or even presently envisioned supercomputer. The wide spectrum of numerical tools available for propulsor design is confusing and at first glance seems redundant. This paper attempts to answer some questions by describing the computational resources required to solve a variety of propulsor problems. Discussion will include considerations of computing speed, storage requirements, computer architecture and graphics capability. The hydrodynamics underlying the various numerical algorithms will be addressed briefly, and references will be given to more complete presentations of the theories employed.
