COMPOSITE BLADE STRINGER RUN OUT

摘要

The technology described herein is intended to improve on the stress performance achieved at the end (run-out) of a composite blade stringer. This is achieved by tailoring the profile of the stringer and tailoring the carbon fibre layup. The technology combines a number of features that reduce the overall sectional area of the stringer towards the stringer end. The 0° plies are also removed toward the stringer end in order to make the stringer softer.
