Abstract
A compressor stator vane includes pressure and suction sides extending chordally between leading and trailing edges, and longitudinally between a root and a tip. The vane narrows in chord to a waist between the root and tip. The vane may also be bowed at its trailing edge in cooperation with the narrow waist.
Claims27
A compressor stator vane comprising pressure and suction sides extending in a first plane chordally between leading and trailing edges, and longitudinally between a root and tip, and narrowing in chord to a waist therebetween, with said leading edge being generally straight in an orthogonal second plane.
A compressor stator vane comprising:
- pressure and suction sides extending in a first plane chordally between leading and trailing edges, and longitudinally between a root and tip, and narrowing in chord to a waist therebetween, with said leading edge being generally straight in an orthogonal second plane;
- and
- said suction side is bowed at an obtuse angle between said trailing edge and each of said root and tip in said second plane.
A compressor stator vane 18 comprising a scalloped leading edge with a waist of minimum chord in a first plane, and a trailing edge bowed orthogonally relative to said leading edge in an orthogonal second plane.
