  • Process for manufacturing a single-piece blisk by cutting with an abrasive water jet
    Patent number: 8732949
    Abstract: A process for manufacturing a single-piece blisk, including: using an abrasive water jet to cut a block of material, so as to create blade preforms extending radially from a disk, then milling the blade preforms.
    Type: Grant
    Filed: March 25, 2009
    Date of Patent: May 27, 2014

  • Process for manufacturing a single-piece blisk with a temporary blade support ring arranged at a distance from blade tips
    Patent number: 8505202
    Abstract: A process for manufacturing a single-piece blisk, including: using an abrasive water jet to cut a block of material, so as to create blade preforms extending radially outwards from a disk, while keeping material to form a connecting mechanism between directly consecutive blade preforms, the cutting being done such that the connecting mechanism approximately forms a ring at a radial spacing from the disk, connecting the blade preforms together at a radially inwards distance from their tips, and then removing the connecting mechanism.

  • Process for manufacturing a single-piece blisk with a temporary blade support ring removed before a milling step
    Patent number: 8464425
    Abstract: A process for manufacturing a single-piece bladed disk, including: using an abrasive water jet to cut a block of material, so as to create blade preforms extending radially outwards from a disk, while keeping material forming a connecting mechanism between at least two directly consecutive blade preforms, the connecting mechanism being at a radial spacing from the disk; then removing the connecting mechanism; then milling the blade preforms.

  • Method for manufacture of an integrally bladed rotor, with temporary blade-holding ring
    Patent number: 8434224
    Abstract: A method to manufacture an integrally bladed rotor, including: cutting a block of material by an abrasive waterjet, undertaken so as to reveal blade preforms extending radially from a disk, while retaining the material forming a linking mechanism between at least two preforms of directly consecutive blades, wherein the linking mechanism is spaced radially from the disk; followed by removal of the linking mechanism.

  • Process for manufacturing a single-piece blisk with a temporary blade support ring removed after a milling finishing step
    Patent number: 8429817
    Abstract: A process for manufacturing a single-piece blisk, including: using an abrasive water jet to cut a block of material, so as to create blade preforms extending radially outwards from a disk, while keeping material forming a connecting mechanism between at least two directly consecutive blade preforms; then milling on the blade preforms so as to obtain profiled blade blanks; then a finishing by milling of the blade blanks, so as to obtain blades with a final profile; then removing the connecting mechanism.
