摘要：With regard to hollow blades for turbine engines, it will be understood there isa problem with respect to percussive impact resulting in excessive distortion of the bladeas well as potential failure as a result of blade tip bulging. By provision of ridges 107, 207,307 which coincide and engage each other under impact, the extent of impactdeformation is limited as well as a result of the narrowing between the ridges, a

reduction in the possibility for fragmentary insert movement to bulge the cavity towardsthe tip 102, 202, 302 of a blade 100, 200, 300.
