Abstract
The present disclosure relates to a variable stator vane and a method of fabricating the variable stator vane of a gas turbine engine. The method includes providing at least one fibre sheet. The method further includes rolling the at least one fibre sheet around a mandrel to form a spindle section of the variable stator vane. An excess of material of the at least one fibre sheet remains after forming the spindle section. The method further includes using the excess of material of the at least one fibre sheet to form the at least one aerofoil section of the variable stator vane.
Claims20
A method of fabricating a variable stator vane, the method comprising:
- providing at least one fibre sheet;
- rolling the at least one fibre sheet around a mandrel to form a spindle section of the variable stator vane, the spindle section having a spindle axis, wherein an excess of material of the at least one fibre sheet remains after forming the spindle section and a first portion of the at least one fibre sheet extends further in a direction along the spindle axis than a second portion of the at least one fibre sheet to form a projection in the spindle section;
- and
- using the excess of material of the at least one fibre sheet to form at least one aerofoil section of the variable stator vane.
A variable stator vane configured for rotation about a rotation axis, the variable stator vane comprising:
- a spindle section formed from a first portion of an at least one continuous fibre sheet wrapped around a spindle axis of the variable stator vane;
- and
- at least one aerofoil section at least partially formed from an excess of material from a second portion of the at least one continuous fibre sheet,
- wherein the first portion of the at least one continuous fibre sheet extends further in a direction along the spindle axis then the second portion of the at least one continuous fibre sheet to form a projection in the spindle section.
