ABSTRACT:
A variable stator vane assembly suitable for a power turbine in which each stator vane is provided at its radially inner and outer extents with disc-shaped platforms which locate on bushes provided on associated support structure. The bushes are cooled by a flow of cooling air which is of higher pressure than that of the hot gases operationally flowing over the vanes so as to prevent the leakage of such hot gases past the bushes.
