A one-piece cowl is provided for use in assembled relationship with a combustor of a gas turbine engine. The cowl is of a generally annular configuration which defines a central cowl axis, and is axially elongated and aerodynamically contoured relative to the central cowl axis. In order to provide a vibratory damping function for the cowl, a solid lip of increased thickness is formed at a leading edge of the cowl.

[ What is claimed is:] [1.] A one-piece, integrally formed cowl for use in assembled relationship with a combustor of a gas turbine engine, said cowl being of a generally annular configuration defining a central cowl axis and being axially elongated and aerodynamically contoured relative to said central cowl axis, wherein said cowl is located radially adjacent to only one side of a plurality of circumferentially spaced mixers of said combustor, said cowl comprising:(a) an aft section connected to a liner of said combustor;(b) a middle section located upstream of said aft section; and(c) a fore section located upstream of said middle section and being oriented substantiallyperpendicular to said central cowl axis, said fore section increasing in thickness from an initial thickness adjacent said middle section to a maximum thickness in order to form a solid lip at a leading edge of said cowl.
