Abstract
A rotary machine includes a rotatable rotor, blades radially mounted on and spaced apart about the rotor, a stationary casing disposed about and radially outward from the rotor and blades defining an annular gap between the casing and tips of the blades, and a flexible abradable seal assembly attached on the casing and disposed within the annular gap such that during differential growth of the rotor and blades relative to the casing the seal assembly flexes and abrades in response to contact by the blade tips and thereby clearance between the casing and blade tips is controlled as to avoid contact by the moving blade tips with the casing.
