Abstract
A compressor stator vane for a gas turbine engine comprised of a leading edge section and a trailing edge section and constructed so that either or both sections may be rotated about a common axis of rotation to vary vane camber with torque for rotating the sections being applied around the engine perimeter.
Claims6
A compressor stator vane for a gas turbine engine, said vane having a leading edge section and a trailing edge section, each section having a shaftlike portion extending through the outer casing of said engine, a shaftlike projection supporting an inner shroud of said engine, and an airfoil portion between said shaftlike portion and said shaftlike projection, means connected to the shaftlike portion of each edge section for adjusting the position of each edge section, and control means connected to said section adjusting means to actuate said section adjusting means and vary the camber of said vane.
