Abstract

A blade 10 for a gas turbine engine has a non-linear stacking axis 30 with portions 40, 42 of differing slopes. The slopes of the portions 40, 42 are of opposite signs. The arrangement provides a compressive component of bending stress on the trailing and leading edges due to centrifugal forces when in use. <IMAGE>
