Clearance control system for a gas turbine engine section

摘要

A section (18) of a gas turbine engine (10) includes a case structure (30) having a first coefficient of thermal expansion. A continuous, ring-shaped liner (44) has a second coefficient of thermal expansion that is substantially different than the first coefficient of thermal expansion. A flexible leaf member (46) operatively connects the liner (44) to the case structure (30). The leaf member (46) is configured to accommodate diametrical change in the liner (46) throughout various fan section-operating temperatures.
