ABSTRACT:
A gas turbine engine turbine is provided with an annular array of nozzle guide vanes which define a radially inner annular platform. The radially outer surface of the platform is configured so as to define a plurality of convex and concave portions. These portions are so arranged as to vary the static pressure of the gases which operationally flow across the vanes in such a manner that the static pressure in the field immediately downstream of the vanes is substantially circumferentially uniform.
