<p>An injection-moulded thermoplastic mini-platform (42) is adhesively bonded, in use, to the aerofoil surfaces of a fan blade (312) in a gas turbine engine. The mini-platform (42) is divided into a number of leaves (46), to increase its flexibility, and ribs (48) beneath the leaves (46) provide additional stiffness in the radial direction. In the event that a fan blade is released in operation, the mini-platform (42) is designed to detach from the blade (312) and/or to break apart, so that damage to other components of the engine is minimised.</p> |
