摘要： The present invention relates to an aerofoil (20) comprising a leading edge portion (22) and a flexible thin-walled portion (26) that is rearwards of the leading edge portion, defining a cavity (28), and a shape-forming insert (30) for inserting into the cavity. The shape-forming insert at least partly defines the profile of the aerofoil such that changing the shape of the insert changes the profile of the aerofoil.

摘要： The present invention relates to an actuatable seal (14) for an aerofoil blade tip, for providing a seal between the blade tip (12) and an adjacent surface (10) over which the blade tip passes in use. The seal comprises a flexible member that is arranged in use to be mounted on the tip of a rotating aerofoil blade and to flex towards the surface under the action of centrifugal force when the blade rotates. The seal further comprises an actuator means provided on the flexible member and operably arranged in use to deflect at least a portion of the flexible member away from the surface.

摘要： The present invention relates to a Test apparatus (10) for testing the interaction between through-thickness compression and shear in a test piece (16). The apparatus comprises first and second chocks (12, 14) arranged in use to securely retain a test piece, and first and second races (18, 20) which can be controllably urged towards each other to transmit a known force to the first and second chocks. The first and second chocks and the test piece together form a substantially cylindrical body of a first diameter and. The first and second races define therebetween a substantially cylindrical space of a second diameter for accommodating the chocks, and wherein the second diameter is greater than the first diameter.

摘要： An airfoil has a hollow shell providing external airfoil surfaces, and a corrugated core within the shell. The core contacts inner surfaces of the shell to support the shell. The airfoil is formed by consolidating a hollow shell pre-form and a corrugated core pre-form. At least a part of the hollow shell has a leading edge shell portion and/or a trailing edge shell portion which, before consolidation of the pre-forms, is a unitary body having a shape which wraps around the respective edge.
