  • Patent number: 10415412
    Abstract: A rotatable arrangement for a gas turbine engine comprises a plurality of blades having an aerofoil profile with a suction side, a pressure side, a leading edge and a trailing edge. A plurality of annulus fillers are provided between adjacent blades. A pressure side seal extends between a blade and an annulus filler on the pressure side of the blade, and a suction side seal extends between the blade and an annulus filler on the suction side of the blade. The suction side seal comprises a blocking member provided at an end of the suction side seal proximal to the trailing edge of the blade, the blocking member being configured to restrict recirculation of flow along the suction side of the blade.

  • Patent number: 10119421
    Abstract: A method is provided of bonding a first component to a second component. The method includes: locating the first component against the second component to form an interface between the components, a curable adhesive being provided at the interface; locating a pressurizable, fluid-filled bladder against the first component such that the first component is sandwiched between the second component and the bladder; locating a backing member against the bladder such that the bladder is sandwiched between the backing member and the first component; pressurizing the bladder such that a consolidating pressure is exerted by the bladder on the first component to conform the first component to the second component; and curing the adhesive while the first component is conformed to the second component by the consolidating pressure.
