Abstract: A panel arrangement comprising a first panel, comprising a first connector permanently bonded to an end edge thereof; and, a second panel, comprising a second connector permanently bonded to an end edge thereof; wherein the first and second panel are in end-on abutment via the first connector and second connector, and wherein the first and second connectors are fastened together by a fastener.

Abstract: A vane for an exhaust system duct in a gas turbine engine including a vane plate, a guide plate, and a baffle. The vane plate includes a leading edge, a first leg and a second leg, with the first and second legs respectively extending on opposing sides of the leading edge to form a substantially U-shaped profile. The baffle connects respective distal ends of the first and second legs. The guide plate is accommodated within the vane plate, and includes a first aperture extending along the guide plate and aligned with the leading edge. The vane further includes a fluid inlet arranged, in use, to direct a fluid flow from outside the duct into an interior of the vane.

Abstract: A compliant element has first and second sections which are separated by a gap. The first and second sections have respective surfaces opposing each other across the gap. The first and second sections are interconnected by flexure elements which are integral with the first and second sections and which extend across the gap. At least part of each flexure element extends obliquely across the gap. Movement of the sections towards and away from each other is accompanied by flexing of the flexure elements.

Abstract: A heat and/or fire protection assembly for a component, the assembly comprising: a plurality of protrusions distributed about a surface of the component, the protrusions protruding with respect to the surface of the component; the protrusions comprising a barrier material, the barrier material being arranged and configured to form a first protective layer under the action of heat, the first protective layer being arranged to protect the component from the heat.

Abstract: Seal assembly for sealing a clearance gap between a boundary of an aperture formed in a housing and a member extending through the aperture. The seal assembly comprises a seal member and a seal member mounting means disposed around the sealing member and is configured to engage with the aperture boundary. The seal member mounting means is configured to seal an alignment interspace provided in the clearance gap between the seal member and aperture boundary. The seal member mounting means is configurable to permit the seal member to be located at a position relative to the aperture boundary in dependence upon the relative positions of the member and aperture boundary to thereby accommodate misalignment between the member and aperture boundary. The seal member mounting means is configurable to lock the seal member relative to the aperture boundary in said position.

Abstract: A compliant structure comprises first and second sections 22, 24 which are separated by a gap 26 but connected by flexure elements 28. The element is compliant in the direction to close the gap 26. The element may take the form of a seal to fit between flanges 12, 14 (FIG. 1) engaging sealing surfaces 30, 32 of the element. Alternatively, a plurality of the elements may be formed into a partitioned structure which is compliant in one direction but relatively stiff in other directions.

Abstract: An intake duct for a compressor comprises an inlet and an outlet means. The duct has a serpentine path. The outlet means comprises a first outlet and a second outlet. The duct further comprises at least one grille member configured to prevent the passage of objects over a predetermined size which is positioned in the duct out of the line of sight when viewed through the inlet. The duct is shaped such that in operation objects passing through the at least one grille member greater than a predetermined mass are directed towards the first outlet and the remainder of the objects are directed towards the second outlet. The first outlet leads overboard and/or to a trap and the second outlet leads to a compressor.
