Axial-Momentum Theory for Propellers in Compressible Flow

Abstract

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. These differences are greatest at high Mach numbers and high power loadings, but, because the magnitudes of the effects of these differences cannot yet be evaluated, the possibility of encountering important effects under less extreme conditions should not be overlooked.
