СТАТОРНЫЙ БАНДАЖНЫЙ ЭЛЕМЕНТ МНОГОСТУПЕНЧАТОЙ ГАЗОВОЙ ТУРБИНЫ, СЕГМЕНТ СТАТОРНОГО БАНДАЖА И СПОСОБ ОТСОЕДИНЕНИЯ И УДАЛЕНИЯ ПЕРВОГО ВНУТРЕННЕГО БАНДАЖНОГО ЭЛЕМЕНТА

摘要

A stator shroud segment is provided that includes an outer shroud having a leading edge groove and a trailing edge groove, both grooves of the outer shroud opening in a first, axial direction; and a plurality of inner shrouds each having a leading edge hook and a trailing edge hook. The hooks of the inner shrouds project in a second, axial direction, diametrically opposite the first axial direction and the leading and trailing hooks of each of the inner shrouds are respectively engaged with the leading and trailing edge grooves of the outer shroud so as to axially and radially lock the inner shrouds to the outer shroud. The assembly simplifies access to and removal of the inner shroud(s) without added complexity.
