Abstract
A swirler 50 for a gas turbine engine combustor 10 has an outer wall 54, groupings 52 of vanes 42 attached to the outer wall, a centerbody 60 mechanically decoupled from the outer wall via the groupings of vanes so that the swirler can accommodate differential rates of thermal growth between the outer wall and the inner centerbody and vanes. Alternatively, the centerbody may be attached to one of the groupings of vanes to keep the centerbody from vibrating.
