A flexible flange (300) for a blade root wall (302) allows movement of the blade root (209) toward and away from the bulkhead (304). The flexible flange provides flexibility and support for the blade wall and also provides a sealant, thereby protecting the machinery in the hub (110). The flexible flange has a top portion (306) configured to be secured to a blade root wall, a bottom portion (310) configured to be secured to a bulkhead (304) and an angled portion (308) configured to offset the top portion from the bottom portion, a gap (312) being between the blade root wall and the bottom portion to allow for movement of the blade root wall toward and away from the bulkhead.
