BLADE OF GAS TURBINE ENGINE FOR AIRBORNE VEHICLE, AND ITS MANUFACTURING METHOD

摘要

FIELD: engines and pumps. ^ SUBSTANCE: during manufacture of gas turbine engine blade using multiple prepreg sheets of composite material, which contain reinforced fibre and have thermoplastic polymer as their matrixes, there formed is laminated material by means of lamination of prepreg sheets on flat surface in thickness direction. Manufactured laminate is subject to heating and action of pressure and moulded to laminated shape. Then, the laminate moulded to laminated shape is subject to heating again and moulded to blade part with three-dimensional shape of curved surface. Multiple blade parts are put on each other and after that interconnected till complete part is obtained by heat supply and application of pressure for obtaining the three-dimensional surface of the blade. ^ EFFECT: invention allows simplifying the manufacture of gas turbine engine blade from composite material. ^ 3 cl, 9 dwg
