摘要： A unison ring assembly for a gas turbine engine has a unison ring and a plurality of levers extending from the unison ring. Each lever has a pin at one end that inserts through a bore of a respective bush mounted in the unison ring. Each bush is formed as separate first and second parts which are mounted to their through-hole by inserting the first part into the through-hole from one side of the unison ring and the second part into the through-hole from the opposing side of the unison ring. Each part has a respective stop which prevents that part from inserting into the through-hole by more than a predetermined amount. When both parts are inserted by their predetermined amounts, their ends join together to form the bush and prevent the parts being retracted from the through-hole.

摘要： There is disclosed a stator vane assembly comprising a support structure 14 arranged to be mounted to a mounting structure 16, a stator vane 12 radially extending from the support structure 14 and a continuity member 28 coupled to the support structure 14 and arranged in use to extend between the mounting structure 16 and the support structure 14 so as to provide a substantially continuous gas-washed surface across the mounting structure 16 and the support structure 14. There is also disclosed a method of forming a stator vane assembly, the method comprising the steps of forming at least one stator vane radially extending from a support structure having a continuity member coupled thereto.
