Abstract
An air cooled guide vane (20) is provided with a stack of ducts (40) each of which converges towards its outlet end. Air flow turbulators (42) are positioned in ducts (40) and pressure losses in the air flow brought about by flowing over the turbulators (42), is recovered by the constricting effect of the ducts (40).
Claims6
A gas turbine engine guide vane comprising a hollow aerofoil having inner wall surfaces and a trailing edge containing a stack of cooling air flow ducts aligned chordally of the aerofoil and defined in part by said inner wall surfaces of said aerofoil, and in part by webs which span the space between said inner wall surfaces, said webs being shaped so that their facing surfaces converge in a direction towards the trailing edge of said aerofoil.
