摘要： A burner for a gas-turbine engine has a frustoconical burner shell, at least two swirler arrangements, which are connected to the shell and are spaced apart around the circumference of the shell between its two ends, and a combustion chamber disposed downstream of a wider end of the shell. Each of the swirler arrangements includes an air swirler and a pre-combustion chamber disposed downstream of the air swirler, and a longitudinal axis of each swirler arrangement intersects a line parallel to, and spaced apart from, the longitudinal axis of the shell. The swirler arrangements are preferably connected to the shell at the same axial point.

摘要： A method of determining the diameter of a hole extending from a surface of an electrically conducting workpiece into or through the workpiece 1 is provided. The hole is defied at the workpiece's surface by an edge of diameter to be determined. For determining the diameter, the workpiece is electrically charged so that discharge occurs at the edges. The discharge current is measured and the diameter of the hole is determined from the measured discharge current.
