A sealing assembly comprising:
- a first member that is part of or is attached to a wind turbine nacelle and extends in a longitudinal direction towards a wind turbine rotor hub, and
- a second member that is part of or is attached to the wind turbine rotor hub and extends in a longitudinal direction towards the wind turbine nacelle;
- the second member rotatable relative to the first member,
- the first member and the second member spaced apart and defining an inner gap therebetween, the inner gap defining a first portion of a tortuous gap,
- a plate attached to the first member and extending in a longitudinal direction towards the wind turbine rotor hub, the plate spaced from the second member, wherein the plate and the second member define a second portion of the tortuous gap,
- the sealing assembly further comprises a brush type sealing, the brush type sealing comprising:
- a first set of bristles extending from an end of the first member at a first direction;
- a second set of bristles extending from an opposite side of the end of the first member at a second direction that is opposite to the first direction;
