Abstract
A variable camber vane particularly suitable for use as a variable stator vane (20) has a secured root (22), a free tip (24) and a working face (26) disposed within and diverting flow of a working fluid, exhibiting temperature-responsive deflection of the tip as respects the root correllative to the temperature of the working fluid, is comprised of a sintered, generally laminar composite of a first amorphous metallic composition as a first vane element (32) and a second amorphous metallic composition as a second vane element (34), wherein the coefficients of thermal expansion for each of the compositions differ; whereby the camber of the vane varies in response to thermal variations of the working fluid.
