Abstract

An axial fan for a ramjet engine prime mover. A ramjet engine power generator is provided with supersonic ramjets at the distal ends of a low aerodynamic drag rotor. The rotor is affixed at a central hub to a shaft, and rotates about an axis defined by the shaft. An axial fan, with output longitudinally along the inlet side of said shaft, supplies inlet air to the ramjet engine. Efficient mixing of the oxidant and fuel prior to entry into the ramjet combustor, and the short residence times in the combustion chamber, minimize the formation of undesirable oxides of nitrogen.
