Classification: CPC F | IPC F

Claim 0:
1. An assembly for a compressor section of a gas turbine engine, the assembly comprising:
an outer shroud and an inner shroud defining a substantially annular gas path therebetween, the gas path having a central axis and extending axially along the central axis;
a plurality of struts extending radially in the gas path, the struts being angularly spaced-apart around the central axis, two adjacent struts defining a strut passage therebetween, the strut passage extending axially along the central axis between leading edges of the two adjacent struts and trailing edges of the two adjacent struts; and
a plurality of variable orientation guide vanes extending radially in the gas path, the variable orientation guide vanes being uniformly angularly spaced-apart around the central axis, two adjacent variable orientation guide vanes of the plurality of variable orientation guide vanes having a leading edge axially overlapping the strut passage at one or more orientations of the two adjacent variable orientation guide vanes,
wherein:
one of the plurality of struts is angularly positioned between the two adjacent variable orientation guide vanes;
a first of the two adjacent variable orientation guide vanes is pivotable about a pivot point; and
a first angular spacing between the one strut and the first of the two adjacent variable orientation guide vanes is greater than a chordwise distance between the leading edge of the first of the two adjacent variable orientation guide vanes and the pivot point.
