  "textContent": "This application describes a leaf seal arrangement, comprising: a first component having a high pressure area and a low pressure area therein; a second component which passes from the high pressure area to the low pressure area; a leaf seal having an array of leaf elements between the high and low pressure areas, each leaf element having a fixed end and a free end, wherein the fixed end is attached to the first component and the free end defines a sealing surface through which the second component sealably passes, a sealing gap therebetween, and wherein the sealing gap generally converges from the high pressure area toward the lower pressure area. Also described is a method of providing a leaf seal which comprises determining the expected amount of deflection which will be experienced between the first and second components at the sealing gap during normal operation; determining a required amount of convergence in the sealing gap to accommodate the expected amount of deflection; configuring either or both of the leaf seal and the second component to provide the required convergence.",
