  • Method for reshaping a gas turbine engine combustor part
    Patent number: 4498617
    Abstract: A combustor liner for a gas turbine engine, which has become distorted during use or repair, is restored to its original dimensions by selective heating at two circular locations, accompanied by outward radial replacement. An induction coil is used to heat the liner. When the support ring parts are also replaced, the high temperature mechanical reforming procedure is such that the subsequent distortion which accompanies the welding replacement of support rings is compensated for.
