A METHOD OF MAKING A ROOT END JOINT OF A WIND TURBINE BLADE AND A ROOT SEGMENT FOR SUCH A JOINT |
摘要 |
A method of making a root end joint for a wind turbine. A plurality of root segments (10) are formed of a composite material. Each has an arcuate end face (11) which subtends an angle of 90° or less and has a plurality of connection holes (12). The segments are joined together side-by-side to build up the circular profile of the root end. The segments include a proportion of uni-axial to multiaxial fiber which decreases from the arcuate end face towards the opposite end. |
