  • System and a method for assembling a rotor stack
    Patent number: 7792600
    Abstract: A system for assembling a rotor stack having a plurality of rotor disks may include a measurement system for measuring characteristics of the rotor disks, a computer electronically connected to the measurement system for capturing data from the measurement system, and solid modeling software for creating a virtual stack of the rotor disks optimized for concentricity.
    Type: Grant

  • Method and apparatus for relieving stress in a combustion case in a gas turbine engine
    Patent number: 6681577
    Abstract: A combustion case for a gas turbine engine. A typical combustion case is generally cylindrical or conical. Apertures penetrate the case, from the outer surface, through the case, to the inner surface. The apertures act as concentration points for stress. To dissipate the stress, bosses buttress the apertures, with each aperture having two bosses: one on the outer surface of the case, and another on the inner surface of the case. The invention eliminates the latter bosses. The invention dissipates stress by providing an array of T-slots on the inner surface.
