Patent number: 9782918Abstract: A molding apparatus for manufacturing a wind turbine blade component includes a main mold body (30) and a flexible bladder (38). The main mold body includes a shape defining surface (32) for receiving composite material forming the blade component and a heat reservoir (40) for heating the blade component during curing. The flexible bladder overlays and conforms to the shape of the blade component and is configured to receive heated liquid for heating the blade component during curing. One or both of the main mold body and the flexible bladder is divided into a plurality of zones (58, 66) that are independently controlled by a controller (70) to maintain a generally uniform temperature of the blade component at each zone.Type: GrantFiled: December 14, 2012Date of Patent: October 10, 2017Assignee: Vestas Wind Systems A/SInventors: Olav Davis, Damien Rajasingam, Adam Fisher, Andy Limmack, Tomasz Garstka

Patent number: 9199301Abstract: An apparatus (60) is provided for forming a trailing edge (52) of a wind turbine blade having first and second shells (40, 42). The first and second shells define a gap therebetween, and the apparatus has a first mold component (62) that is adapted to form the first or second shell, and an engaging element (77). The engaging element is configured to securely support a trailing edge component to be coupled to the first and second shells. The engaging element is coupled to the first mold component. The apparatus may additionally include a second mold component (64) that is adapted to form the other of the first or second shells and which is coupled to the first mold component. In this embodiment, the first and second mold components have a closed position in which the first and second shells are closed over one another so as to define a generally closed profile of the wind turbine blade.Type: GrantFiled: August 4, 2011Date of Patent: December 1, 2015Assignee: Vestas Wind Systems A/SInventors: Damien Rajasingam, Richard Evans, Olav Davis, Stephen Sandercock
