Abstract: Control of blade clearance gaps between rotating turbine blades and an associated casing in a gas turbine engine is important in order to maintain operational efficiency. It is desirable to achieve accurate gap control but previous passive and scheduled thermal gap adjustment systems have been relatively course. By provision of a winding through which a specific electrical current is passed in order to create electro-magnetic force for displacement of an armature associated with a seal forming part of the casing it is possible to adjust the gap between that seal and a tip part of a rotating blade assembly. Normally a blade gap monitoring technique is used in association with specific operational requirements with respect to the gap by the control in order to determine the electrical current presented to the winding. As a fail-safe measure a permanent magnet or bias or some other form can be provided to ensure displacement to a fail-safe position with an adequate blade gap clearance for continued operation should there be power failure or an excess electrical current presented to the winding.

Abstract: A control arrangement (34) for controlling the size of a gap (30) between first and second components. The control arrangement comprises first magnet means (38) to be provided on the first component, and second magnet means to be provided on the second component. The first and second magnet means are in magnetic interaction with each other across the gap (30) and the arrangement further includes control means (36) to control the size of the gap (30) the first magnet means (38) is a moveable in a first direction to cause the control means (36) to effect relative movement of the first and second components to increase the gap (30) and in a second direction to cause the control means (36) to effect relative movement of the first and second components to decrease the gap (30). The first and second magnet means are arranged such that relative movement of the first and second components towards each other moves the first magnet means (38) in the first direction, and relative movement of the first and second components away from each other moves the first magnet means (38) in the second direction.

Abstract: A stress wave load cell comprises a propagation member to which is acoustically coupled a transmitting transducer and a receiving transducer. Electrical pulses are supplied to the transducer form a pulse generator and the electrical pulses are converted into stress wave signals which propagate through the propagation member. The transducer detects the stress wave after propagation through the propagation member and supplies an electrical signal to a processor which gives a measure fo the load applied on the load cell.Damping members apply a damping load on the propagation member when a load is applied to the load cell. The damping members damp the propagation of the stress waves in the propagation member and the decay rate of the diffuse stress wave field set up in the propagation member is dependent upon the load applied on the load cell.

Abstract: A rotor blade comprising a core blade section; and a trailing edge section, the trailing edge section being attached to the core blade section along a join interface. The trailing edge section comprises a shape memory material which is actuable so as to cause selective deformation of the trailing edge section between a first condition in which a trailing edge of the trailing edge section follows a substantially smooth profile and a second condition in which the trailing edge is perturbed. The direction of the perturbation may be oblique or perpendicular to the direction of flow over the blade in use. The rotor blade may be a fan or propeller for a gas turbine engine.
