NON UNIFORM VANE SPACING

NON UNIFORM VANE SPACING

The invention discloses a circular row (11) for a non uniform vane spacing blade (15). The circular row includes only one first group (G1) and only one second group (G2) of adjacent vanes (15), unequal first and second spacing (S1, S2) between adjacent vanes (15) in the first and second groups (G1,...

Beschreibung
Zusammenfassung:The invention discloses a circular row (11) for a non uniform vane spacing blade (15). The circular row includes only one first group (G1) and only one second group (G2) of adjacent vanes (15), unequal first and second spacing (S1, S2) between adjacent vanes (15) in the first and second groups (G1, G2), and first spacing (S1) greater than second spacing (S2). An embodiment with second group (G2) includes only three adjacent vanes (15). Second spacing (S2) may be about 25%-35% smaller than a nominal uniform spacing (S) used as a design parameter for designing spacing of the non-uniformly spaced stator vanes (15). Circular row 11 may be sectored. A gas turbine engine section may include one or more rings or circular rows (15)of fixed and/or variable non-uniformally spaced vanes (15). Method for designing non-uniform vane spacing for circular row (15)includes determining nominal uniform spacing (S) and forming first spacing (S1) and second spacing (S2) from nominal uniform spacing (S) of vanes (15). 本发明公开种用于非均匀间
