摘要： A lock for securing a nosecone having first threading to an inlet case having second threading and for use with a gas turbine engine having an axis includes an annular ring designed to be positioned about the first threading. The lock also includes a tab extending radially from the annular ring, and having a ramped circumferential end and an angled circumferential end such that the ramped circumferential end passes over a detent of the inlet case in response to the nosecone being fastened to the inlet case and the angled circumferential end engages with the detent to resist unfastening of the nosecone from the inlet case.

摘要： Vanes are generally hollow with a passage through which service pipes extend. These service pipes must be connected such that they can allow for thermal expansion and contraction but also anti rotation features are needed in order to prevent damage when a supply coupling is connected through a pipe end. This anti-rotation feature is generally provided between a top hat and a pipe end through flanges. In order to allow reduced spacing between the top of the vane and a casing the flanges are arranged to allow at least recessing of a first flange into a passage opening profile whereby those flanges inter-engage with second flanges at a surface interface to prevent rotation.

摘要： There is provided a turbine engine component, such as a duct pipe, comprising an annular flange, at least one element, such as two duct pipe halfs, to be mated to the flange, and mating system for joining the at least one element to the flange. The mating system includes a first annular groove in the flange, which groove has two opposed planar wall portions for preventing axial movement of the at least one element relative to the flange. In a preferred embodiment, the mating system also includes a second annular groove in the flange. A sealing element is positioned within the second annular groove.
