ABSTRACT:
A turbine engine has a circumferentially segmented shroud within a case structure. Each shroud segment is mounted for movement between an inboard position and an outboard position. One or more springs bias the shroud segments toward their inboard positions. One or more valves are positioned to vent one or more volumes so as to counter the spring bias to shift the shroud segments to their outboard positions.
