Method of securing a liner panel to a casing

摘要

A liner panel, such as a cassette 120 of a fan track liner of a gas turbine engine, is secured to a casing of the engine at flanges 124 and 126. Foam pads 42 are disposed between the casing 40 and the cassette 120 to support the cassette 120 from the casing 40. ;The pads 42 may be made from a reticulated polyurethane foam which is sufficiently resilient to be compressed and to expand to remain in contact with the cassette 120 and the casing 40 as the cassette 120 moves towards and away from the casing 40 during the assembly process. The foam is impregnated with a hardener composition which is uncured during installation of the cassette 120, but subsequently cures to increase the rigidity of the pads 42.

1. A method of securing a liner panel to a casing of a turbomachine with a foam material disposed between the liner panel and the casing, the method comprising:
impregnating the foam material with a curable hardener composition; applying a release coating or film to a surface of the foam material adapted to contact the casing; securing the liner panel to the casing to compress the foam material between the liner panel and the casing while the hardener composition is in an uncured condition; and curing, subsequently, the hardener composition to increase the rigidity of the foam material.
