Patent ID: 8794587

Claim:
A mounting apparatus comprising: a mounting pin having first and second ends; an outer casing of an axial compressor of a gas turbine engine, the outer casing having first and second sides, the outer casing including a passage between the first and second sides for receiving the mounting pin so that the first end of the pin protrudes from the first side and the second end of the pin protrudes from the second side, the second end of the pin being configured to engage a stationary vane carrier of the axial compressor to mount the stationary vane carrier, the first end of the pin being operable to rotate the pin about the axis of the pin to vary the position of the stationary vane carrier; and a clamping plate for clamping the first end of the mounting pin to the first side of the outer casing for securing the rotational position of the pin with respect to the outer casing, wherein the first end of the pin includes a first locking taper which, with progression along the axis of the pin away from the second end of the pin, tapers from a first radial distance from the axis to a second reduced radial distance from the axis; and the clamping plate includes a second locking taper complementary to the first locking taper for locking with the first locking taper.
