Abstract
Provided is an apparatus that is able to take preform and create a swept rotor blade in a continuous manner. The apparatus has a feeder frame across which the preform moves in a first direction. A main frame moves with respect to the feeder frame and moves the preform in a second direction that is different than the first direction. In order to avoid wrinkles forming in the preform during the creation of the swept rotor blade a tension component may be applied to a feed angle in order to form the shear angle for deformation.
Claims17
A method for forming a rotor blade comprising:
- feeding a preform mounted on a feeder frame in a first direction through a first pair of rollers having first roll axes and through a second pair of rollers having second roll axes, wherein the second roll axes are movable with respect to the first roll axes in a direction perpendicular to the first roll axes thereby forming a tension component for the preform;
- feeding the preform to a main frame movably connected to the feeder frame, wherein the main frame extends in a horizontal plane and is movable in a second direction with respect to a first direction thereby forming a feed angle γ;
- moving the main frame so that the feed angle γ is greater than zero, wherein the tension component and the feed angle γ form a shear angle β;
- and
- forming a swept rotor blade from the preform using the shear angle β.
An apparatus for forming a rotor blade for a wind turbine comprising:
- a feeder frame extending in a first direction, wherein a preform roll is mounted on the feeder frame;
- a first pair of rollers having first roll axes and a second pair of rollers having second roll axes located on the feeder frame, wherein the second roll axes are movable with respect to the first roll axes in a direction perpendicular to the first roll axes thereby forming a tension component for the preform;
- and
- a main frame movably connected to the feeder frame in a second direction thereby forming a feed angle γ;
- wherein a preform moves along the first pair of rollers and the second pair of rollers forming a tension component and moves along the main frame at a feed angle γ in order to form a shear angle β for forming a swept rotor blade.
An apparatus for forming a blade for a wind turbine comprising:
- a feeder frame extending in a horizontal plane, wherein a preform roll is mounted on the feeder frame;
- a main frame located adjacent to the feeder frame wherein preform moves from the feeder frame to the main frame;
- a means for forming a feed angle γ in the preform as the preform moves through the apparatus;
- and
- a means for forming a tension component in the preform as the preform moves through the apparatus;
- wherein the means for forming the feed angle γ and the means for forming the tension component together form a shear angle β to form a swept rotor blade.
