Abstract:
1. A gas turbine engine comprising: an annular gas path defined through the engine; at least one strut extending generally radially relative to the engine from an inner gas path wall to an outer gas path wall and composed by a peripheral wall enveloping an empty inner space, the strut thereby spanning the gas path, the strut having a leading edge located upstream relative to the annular gas path with a plurality of inlet apertures being radially spaced apart from one another, a trailing edge located downstream relative to the annular gas path with a plurality of outlet apertures being radially spaced apart from one another, the trailing edge being located at a wake effect zone; and at least one strut gas path defined by at least an internal passageway in the empty inner space of the strut, the passageway extending through the empty inner space of the strut between the leading edge and trailing edge apertures, wherein the strut gas path extends in a substantially unobstructed line between the inlet and outlet apertures and through the empty inner space to converge with the annular gas path in the wake effect zone.
