Abstract
Segmented nozzles and tip shoes having improved seals for keeping hot gases from leaking through the gaps between adjacent segments. The seals have an interference fit with grooves in the opposite ends of adjacent segments and span the gaps between those segments. The seals are sufficiently flexible to fit non-parallel grooves, and they may have a concave cross-section which prevents binding and seal distortion in such circumstances.
