Abstract
A fan case assembly comprises a fan track liner, an annular case, and a tip injection system. The fan track liner includes a forward end, an aft end axially aft of the forward end, and an inner radial surface that extends between the forward and aft ends to define a gas path. The tip injection system includes an air recirculation duct configured to direct a portion of gases flowing through the gas path from the aft end of the fan track liner into the gas path adjacent the forward end of the fan track liner and a thermal conditioner in thermal communication with the air recirculation duct. The thermal conditioner includes phase change material configured to extract heat from the portion of gases flowing through the air recirculation duct to cool the portion of gases and minimize thermal distortion induced by the portion of gases.
