Method of manufacturing a shell of a wind turbine blade

A method for joining a spar element to a wind turbine blade, the method comprising:

• positioning a first half of the spar element on a first shell half structure or a first spar cap of the wind turbine blade and positioning a second half of the spar element on a second shell half structure or a second spar cap of the wind turbine blade, wherein the spar element is a spar beam receiver section or a portion of a spar beam receiver section, and wherein the spar beam receiver section is configured to receive a beam structure of a blade segment;
• and
• infusing resin between the first half of the spar element and the first shell half structure or the first spar cap and subsequently curing the same to adhere the first half of the spar element to the first shell half structure or the first spar cap of the wind turbine blade;
• infusing resin between the second half of the spar element and the second shell half structure or the second spar cap and subsequently curing the same to adhere the second half of the spar element to the second shell half structure or the second spar cap of the wind turbine blade;
• adhering the first half of the spar element to the second half of the spar element;
• and
• then, joining and sealing the first shell half structure and the second shell half structure.

A method for manufacturing a root end segment of a wind turbine blade, the method comprising:

• forming a first shell half structure and a second shell half structure separately in a mould;
• joining, by a resin infusion process in the mould, a first half of a spar element to the first shell half structure and joining, by the resin infusion process in the mould, a second half of the spar element to the second shell half structure, wherein the spar element is a spar beam receiver section or a portion of a spar beam receiver section, and wherein the spar beam receiver section is configured to receive a beam structure of a blade segment;
• positioning a shear web at a central portion of the first shell half structure and the second shell half structure, wherein the shear web extends in a spanwise direction up to the spar element;
• joining an end of the spar element and the shear web;
• joining and sealing the first shell half structure and the second shell half structure to obtain the root end segment of the wind turbine blade;
• and
• adhering the first half of the spar element to the second half of the spar element before the joining of the first shell half structure and the second shell half structure.
