Abstract
A fuel injection strut for a ramjet adapted to operate at high Mach numbers includes a combustion chamber into which a flow of combustion-supporting gas is introduced. A first end of the strut includes a stem having a leading edge with a dihedral shaped wall for defining a chamber on a concave side for receiving the flow of combustion supporting gas. An injection member generates a plurality of jets impinging cooling fluid on the concave side of the wall to cool the strut. The leading edge provides two-way permeability so that at lower speeds, air permeates through the leading edge to facilitate pilot combustion in the combustion chamber, and a higher speeds, the cooling fluid permeates through the leading edge to cool the strut.
