Abstract
A method and a device (10) are provided for curing a bond joint in a wind turbine blade manufacturing process. The device (10) comprises a mobile frame (20), a root cap (30) configured to be coupled to a root end of a wind turbine blade (6) that is being manufactured, a seal (50) provided on the root cap (30), a hot air duct (41) passing through the root cap (30) and arranged to blow hot air into a blade cavity of the wind turbine blade (6), and a return duct (43) passing through the root cap (3) and arranged to receive a return flow of air from the blade cavity. The method comprises mechanically coupling the root cap (30) to the root end, inflating an inflatable seal (50), and blowing hot air through into the blade cavity.

A method of curing a bond joint in a wind turbine blade manufacturing process, the method comprising:
- mechanically coupling a root cap to a root end of a wind turbine blade that is being manufactured,
- inflating an inflatable seal for sealing a connection between the root cap and an inner surface of the root end of the wind turbine blade, and
- blowing hot air through a hot air duct in the root cap, into a blade cavity of the wind turbine blade.
A mobile heating device for curing a bond joint in a wind turbine blade, the mobile heating device comprising:
- a mobile frame,
- a root cap, supported by the mobile frame and configured to be coupled to a root end of a wind turbine blade that is being manufactured, a seal, provided on the root cap and arranged for sealing a connection between the root cap and a surface of the root end of the wind turbine blade,
- a hot air duct, passing through the root cap and arranged to blow hot air into a blade cavity of the wind turbine blade, and a return duct, passing through the root cap and arranged to receive a return flow of air from the blade cavity.
