Abstract
The invention provides a wind turbine blade body manufacturing method, the method comprising the steps of: providing a mould (40) having an elongated mould surface (43), placing a movable insert (50) on the mould surface, in a first position, forming, with the insert in the first position, a first blade body having a first length (L1), placing the insert (50) on the mould surface, in a second position, and forming, with the insert in the second position, a second blade body having a second length (L2) which is different from the first length.
Claims16
A wind turbine blade body manufacturing method, the method comprising the steps of:
- providing a mould having an elongated mould surface,
- placing a movable insert on the mould surface, in a first position,
- forming, with the insert in the first position, a first blade body having a first length,
- placing the insert on the mould surface, in a second position, and
- forming, with the insert in the second position, a second blade body having a second length which is different from the first length, wherein:
- a difference, at the first position and at the second position, of the orientation of the insert around a longitudinal axis of the mould surface, is linearly dependent on the distance between the first position and the second position, and/or
- a difference, at the first position and at the second position, of the orientation of the insert around a lateral axis of the mould surface, is linearly dependent on the distance between the first position and the second position.
A wind turbine blade body manufacturing apparatus comprising:
- a mould, having an elongated mould surface extending from a mould root end to a mould tip end, and
- a movable insert, the apparatus being arranged to allow the insert to be placed on the mould surface, in a plurality of positions along the longitudinal direction of the mould surface, for forming blade bodies having respective lengths which are dependent on the insert position along the longitudinal direction of the mould surface,
- wherein, in the constant cross-section portion, a twist of the mould surface changes linearly in the longitudinal direction of the mould surface.
