Abstract (en)
A gas turbine section for an annular gas path is presented. The annular gas path is defined through a gas turbine engine. The gas turbine section includes an inner and an outer gas path walls that are concentrically arranged about an axis and adapted to form together at least a part of the annular gas path defined through the gas turbine engine. The gas turbine section includes at least one strut extending generally radially relative to the axis from the inner to the outer gas path walls. The strut has a leading edge, adapted to be positioned upstream relative to the annular gas path, and a trailing edge, adapted to be positioned downstream relative to the annular gas path. The strut further includes a cut-out. The cut-out is positioned at the trailing edge and is contiguous with the inner gas path wall or the outer gas path wall. Corresponding methods of designing and manufacturing a gas turbine section.
