Open the CIPO recordAbstract From the Canadian patent
The invention comprises a blade for a gas turbine engine including an airfoil portion having a non-linear stacking axis which is effective for generating a compressive component of bending stress due to centrifugal force acting on the blade. The compressive component of bending stress is provided in a lifelimiting section of the blade, which, for example includes trailing and leading edges of the blade. Inasmuch as the stacking axis which represents the, locus of centers of gravity of transverse sections of an airfoil portion of the blade, is non-linear an, increased amount of a compressive component of bending stress can be generated at a life-limiting section between root and tip sections …
