Frame assembly, mold, and method for forming rotor blade
Frame assemblies, molds, and methods for forming rotor blades are provided. A frame assembly for a rotor blade mold includes a plurality of frames, at least one of the plurality of frames movable relative to the others of the plurality of frames, and a bed supported by the plurality of frames. Movement of the at least one of the plurality of frames causes a modification of the bed along a width-wise axis. A mold for forming a rotor blade includes a frame assembly and a mold material disposed in the bed of the frame assembly.
1. A frame assembly for a rotor blade mold, the frame assembly comprising:
a plurality of frames, at least one of the plurality of frames movable relative to others of the plurality of frames, each of the plurality of frames comprising a generally stationary base and a frame member slidable along a longitudinal axis of the base; and
a bed supported by the plurality of frames, the bed defining a length-wise axis and a width-wise axis, the stationary base and the frame member extending longitudinally along the width-wise axis of the bed,
wherein movement of the at least one of the plurality of frames causes a modification of the bed along the width-wise axis.
2. The frame assembly of claim 1 , wherein the longitudinal axis is generally parallel to the width-wise axis.
3. The frame assembly of claim 1 , wherein the frame member is a plurality of frame members, and each of the plurality of frame members is further movable relative to others of the plurality of frame members.
4. The frame assembly of claim 1 , wherein the at least one of the plurality of frames is displaceable.
5. The frame assembly of claim 1 , wherein the at least one of the plurality of frames is expandable.
6. The frame assembly of claim 1 , wherein the movement of the at least one of the plurality of frames causes displacement along the width-wise axis of a portion of the bed supported by the at least one of the plurality of frames.
7. The frame assembly of claim 1 , wherein the movement of the at least one of the plurality of frames causes expansion along the width-wise axis of a portion of the bed supported by the at least one of the plurality of frames.
8. The frame assembly of claim 1 , wherein the bed is formed from one of a corrugated sheet, a honeycomb sheet, or a plurality of overlapping movable panels.
9. The frame assembly of claim 1 , wherein each of the plurality of frames is movable relative to the others of the plurality of frames.
10. The frame assembly of claim 1 , further comprising a bulkhead, the bulkhead positionable in the bed to modify a usable length of the bed.
11. A mold for forming a rotor blade, the mold comprising:
a frame assembly, the frame assembly comprising a plurality of frames and a bed supported by the plurality of frames, the bed defining a length-wise axis and a width-wise axis,
at least one of the plurality of frames movable relative to others of the plurality of frames, wherein movement of the at least one of the plurality of frames causes a modification of the bed along a width-wise axis, and wherein the at least one of the plurality of frames comprises a generally stationary base and a frame member slidable along a longitudinal axis of the base, the stationary base and the frame member extending longitudinally along the width-wise axis of the bed; and
a mold material disposed in the bed.
12. The mold of claim 11 , wherein the mold material is alternatable between a deformable state and a non-deformable state.
13. The mold of claim 11 , wherein the mold material is an epoxy.
14. The mold of claim 11 , further comprising a plug removably insertable into the mold material.
15. A method for forming a rotor blade, the method comprising;
providing a frame assembly, the frame assembly comprising a plurality of frames each disposed in a first position relative to one another, wherein the at least one of the plurality of frames comprises a generally stationary base and a frame member slidable along a longitudinal axis of the base;
inserting a plug into a mold material disposed in a bed of the frame assembly, the bed defining a length-wise axis and a width-wise axis, the stationary base and the frame member extending longitudinally along the width-wise axis of the bed; and
moving at least one frame of the frame assembly to a second position relative to another frame of the frame assembly such that the bed of the frame assembly is modified along a width-wise axis.
16. The method of claim 15 , further comprising causing the mold material to change from a deformable state to a non-deformable state.
17. The method of claim 16 , further comprising removing the plug from the mold material.
18. The method of claim 16 , further comprising causing the mold material to change from the non-deformable state to the deformable state before moving the at least one frame.
