Abstract

1,116,580. Compressor and turbine blades; axial flow compressors. BRISTOL SIDDELEY ENGINES Ltd. Nov. 15, 1966 [Nov. 17, 1965], No. 48898/65. Headings F1C and F1T. The stator blades 10 in a gas or steam turbine or in the axial flow compressor of a gas turbine engine are shaped so that the centroid line 22 of the working portion 19 of each blade diverges at a progressively increasing angle from a radial line 23 through the inner end of the centroid line. The curvature may be only in a plane perpendicular to the machine axis, as shown, or additionally in a plane containing the axis, Figs. 8 to 10 (not shown). In the latter case, the rotor blades are similarly curved. The construction reduces bending stresses on the stator blades and also reduces noise by reducing wake interaction. The stator blades are fixed to the outer casing 13 by engagement of roots 11 in an annular groove 15 and act at their inner ends as the sole support for a ring 14. In the case of a compressor, the blades may be moulded from an epoxy resin reinforced with layers of cloth woven from glass fibres, the blades being mounted by engagement of dovetail roots (26, 27), Figs. 4, 5 (not shown) in corresponding axial recesses in the casing (28) and inner ring (29).
