Abstract

An encapsulated or rigid bundle of rods forms a substantially non-dispersive buffer usable in extreme environments, operable over wide bandwidth, and repairable in the field. The rigid assembly extends through a nozzle or flanged pipe penetration to launch its signals directly in the fluid at a defined angle. The bundles are non-degrading wave guides to carry signals through degrading environments. This is useful for numerous stack, freestream and chordal path configurations, as well as clamp-on systems and special mode-converting configurations. Beam shaping and steering may be passively effected with patterned bundle constructions, and plural faces, which may be stepped or angled, may define multiple oblique, reflective or different length paths while mounted in spoolpieces at normal incidence.
