ROTOR BLADE SHELL, ROTOR BLADE AND WIND TURBINE

The invention relates to a rotor blade shell (110a, 110b), a rotor blade (100) and a wind turbine. The rotor blade shell (110a, 110b) extends from a shell root (400) to a shell tip (401). A layer system of the rotor blade shell (110a, 110b) extending in a longitudinal direction (L) contains a core l...

More Information
Summary:The invention relates to a rotor blade shell (110a, 110b), a rotor blade (100) and a wind turbine. The rotor blade shell (110a, 110b) extends from a shell root (400) to a shell tip (401). A layer system of the rotor blade shell (110a, 110b) extending in a longitudinal direction (L) contains a core layer and two laminates (1a, 2b, 5a, 5b, 21, 51) which are arranged on mutually opposing sides of the core layer. One part of the core layer is formed in a first portion (A) by a rotor blade belt (2a, 2b, 12) which ends at an end (a) of the first portion (A) facing the shell tip. At least one of the two laminates (1a, 2b, 5a, 5b, 21, 51) has, in a second portion (B) which adjoins the first portion (A) at the end (a) of the first portion (A) facing the shell tip, at least one fibre layer (11a, 11b, 15a, 15b, 20, 50) which extends in a transverse direction (Q) from a trailing edge (8) of the shell to a leading edge (9) of the shell and contains fibres, of which a majority extend in the longitudinal direction (L).
