ABSTRACT:
A fluid flow nozzle is formed by a plurality of adjacent L-shaped channels forming successive channel pairs. Each channel has a linking member joined to a radial member. Each linking member is welded to an adjacent linking member forming a contiguous surface of linking members. Each radial member is oriented approximately perpendicular to a first side of the contiguous surface. A circumferentially enclosed chamber is formed on a second side of the contiguous surface. Each radial member is laser welded to a jacket at a distal end of each radial member. The jacket is oriented approximately parallel with the contiguous surface and separably spaced from the contiguous surface by the radial members. Each radial member forms one of a plurality of flow chambers between its adjacent radial member, the jacket and the contiguous surface. The flow chambers advantageously contain fluid in the event of a radial member rupture.
