  • Stack molding pattern and improved shell for manufacturing aircraft turbine engine blade elements via lost wax casting
    Patent number: 10471500
    Abstract: A stack molding pattern and a shell for manufacturing aircraft turbine engine blades via lost wax casting. The stack molding shell includes a plurality of shell blade elements, each intended for producing a blade, wire elements being arranged within the shell blade elements; and a metal feeder including a plurality of metal outlets, each one radially open towards one of the shell blade elements and connected with the second end portion of the element. The shell includes a protective screen, associated with each second end portion and intended to protect a sensitive portion of the wire elements against the direct impact of a flow of metal from the feeder. The sensitive portion is located in the second end portion, downstream from the protective screen.
