Abstract

Hub cooling air control means in a gas turbine engine having a variable pitch rotatable airfoil comprise a platform 26 fixedly attached to a radially inner end of the airfoil, the platform being positioned on a rotatable annular surface 16, which surface defines outer and inner spaces 34, 36. In a first position, an edge portion 38 of the platform substantially conforms to the annular surface, the edge portion being displaced radially outwardly from the surface thereby allowing fluid communication 41 between the outer and inner spaces in a second position. <IMAGE>
