  • Method for release of fan blisk airfoil with external shaped charge
    Patent number: 10260512
    Abstract: According to one aspect, a method of releasing a fan blade for testing a turbofan engine includes arranging an external shaped charge about an airfoil and modifying the airfoil by extricating one or more portions of material from one or more sides of the airfoil. The method further includes detonating the external shaped charge such that the airfoil is released at a selected time.
    Type: Grant
    Filed: July 15, 2016
    Date of Patent: April 16, 2019
    Assignee: Rolls-Royce Corporation
    Inventors: Christopher Hall, Graham Burkholder, Xuekun Sun, Jeff Crutchfield, Ben Hodgson
  • Method of releasing a fan blade and assembly for releasing a fan blade from a turbofan engine
    Patent number: 10113442
    Abstract: According to one aspect, a method of releasing a fan blade for testing a turbofan engine includes providing an internal passage with a constant arc through an airfoil arranged about a blisk such that the constant arc of the internal passage aligns with a contour of the blisk. The method further includes packing the internal passage with a charge, modifying the airfoil such that the airfoil is released from the blisk evenly along a chordwise length of the airfoil, and detonating the charge such that the airfoil is released from the blisk at a selected time.
