The vane assembly has mating vane support and vane ring, the vane ring having a plurality of annularly interspaced radial loading elements which, when the vane ring is assembled to the vane support, are in a resiliently flexed state and exert corresponding annularly interspaced and outward-oriented radial loads against the vane support, thereby restraining relative radial movement between the vane ring and the vane support during operation of the gas turbine engine. The method includes flexing each of the radial loading elements into the resiliently flexed state simultaneously by sliding the radial loading elements against corresponding lead-in tapers. This can be achieved using a guide tool which includes a plurality of segments bearing the lead-in tapers and which is previously assembled to the vane support.
A guide tool for assembling a vane ring with a vane support of a vane assembly in a gas turbine engine, the vane support having radial-facing abutment surfaces, annularly disposed and circumferentially interspaced relative to the longitudinal axis, the vane ring having a plurality of resiliently flexible radial loading elements associated with corresponding ones of the abutment surfaces, the radial loading elements being at a first radial position when in an unflexed state, and being resiliently flexible to a second radial position defining a flexed state, said second radial position corresponding to a radial position of corresponding abutment surfaces of the vane support, the guide tool comprising:
