Abstract
A manufacturing method of a wind turbine generator includes a cutting step of cutting a base blade at m cutting planes into (m+1) sections where m is an even number, the m cutting planes being at different positions in a blade length direction; and joining step of joining (m/2+1) sections of the (m+1) sections together to obtain a wind turbine blade which is shorter than the base blade, the (m/2+1) sections including a blade-root section which is closest to a blade root and a blade-tip section which is closest to a blade tip, the blade-root and blade-tip sections being non-adjacent to each other.

A manufacturing method of a wind turbine, the method comprising:
- a cutting step of cutting a base blade at m cutting planes into (m+1) sections where m is an even number, the m cutting planes being at different positions in a blade length direction;
- and
- a joining step of joining (m/2+1) sections of the (m+1) sections together to obtain a wind turbine blade which is shorter than the base blade, the (m/2+1) sections including a blade-root section which is closest to a blade root and a blade-tip section which is closest to a blade tip, the blade-root and blade-tip sections being non-adjacent to each other.
A wind turbine blade, comprising:
- (m/2+1) sections of (m+1) sections obtained by cutting a base blade in m cutting planes being at different positions in a blade length direction where m is an even number, said (m/2+1) sections being non-adjacent to each other and including a blade-root section which is closest to a blade tip and a blade-tip section which is closest to a blade tip.
A wind turbine generator comprising:
- a wind turbine blade;
- and
- a generator configured to be driven by rotation of the wind turbine blade,
- wherein the wind turbine blade includes a blade-root section which is closest to a blade tip and a blade-tip section which is closest to a blade tip from (m+1) sections obtained by cutting a base blade in m cutting planes being at different positions in a blade length direction where m is an even number, and (m/2+1) sections that are non-adjacent to each other are joined together.
