The axial-momentum theory for compressible flow has been developed as a first step in the formulation of a rational propeller theory for compressible flow. The simple theory, although neglecting such important factors as rotation and profile drag, predicts flow conditions through a propeller that are significantly different from the conditions predicted by the incompressible-flow theory.
