    摘要： An electrochemical machining process for forming a non-circular hole from a substantially circular hole within a workpiece using an electrode. The electrode is made of an electrically conductive material and has insulated areas in which the electrically conductive material is coated with an insulating material, and exposed areas of metal or conductive material. The insulated areas and exposed areas extending in rows substantially along a longitudinal axis of the electrode. The electrode is first positioned in a substantially circular hole. An electric current is then applied to the electrode to electrochemically remove a predetermined amount of material from the substantially circular hole to form a non-circular hole. A variety of different non-circular shapes are achievable using the process.

    摘要： A combustor structure includes a combustor fuel-air mixing apparatus having a mainstream airflow region. One or more concavities are disposed within the mainstream airflow region of the fuel-air mixing apparatus. At least one fuel injection hole is disposed within an upstream base region of at least one concavity. Passing a stream of air through the main airflow region causes fuel injected into the upstream base region of at least one concavity to passively mix with a naturally oscillating vortex of air within the concavity.

    摘要： A stator-rotor assembly which includes at least one interface region between the stator and rotor is described. At least one stator or rotor surface in the interface region includes a pattern of inverted turbulators. The inverted turbulators restrict gas flow through a gap between the stator and the rotor. Various turbomachines which can contain such a stator-rotor assembly are also described. The disclosure also discusses methods to restrict gas flow through gaps in a stator-rotor assembly utilizing the inverted turbulators.
