An aerofoil configured to be connected to a second component, the aerofoil comprising:
- a first face including a bi-cast groove for joining the aerofoil to the second component by bi-casting;
- a second face connected to a gas path surface of the aerofoil;
- an angled sealing face between the first and second face, the angled sealing face being angled with respect to the second face and configured to provide a sealing interface between the first face and the second face;
- and
- a concave face forming a recessed surface at the intersection of the sealing face and the second face.
A method of manufacturing an aerofoil comprising:
- providing an aerofoil with a first face including a bi-cast groove;
- a second face connected to a main body of the aerofoil;
- and an angled sealing face between the first and second face, the angled sealing face being angled with respect to the second face and configured to seal the bi-cast groove;
- and
- removing material at the intersection of the angled sealing face and the second face to form a concave face, thus forming a recessed surface.
