Abstract

1. Охлаждаемая лопатка газовой турбины, содержащая полое перо, в зоне входной кромки которого в продольном пазу расположена вставка из материала, отличного от материала лопатки, отличающаяся тем, что, с целью повышения надежности, перо снабжено поперечными выступами, размещенными в пазу пара, а вставка выполнена составной из нескольких элементов, каждый из которых со стороны полости пера имеет хвостовик с наклонными боковыми поверхностями, контактирующими с выступами.2. Лопатка по п.1, отличающаяся тем, что каждый выступ снабжен по крайней мере одним поперечным ребром, а хвостовик - ответной канавкой.3. Лопатка по пп.1 и 2, отличающаяся тем, что внешняя поверхность вставки наклонена к оси турбины под углом, не превышающим 90°.1. The cooled blade of the gas turbine, containing a hollow feather, in the zone of the input edge of which in the longitudinal groove is an insert made of a material different from the material of the blade, characterized in that, in order to improve reliability, the feather is provided with transverse projections placed in the steam groove the insert is made up of several elements, each of which, from the side of the pen cavity, has a shank with inclined side surfaces in contact with the protrusions. A blade according to claim 1, characterized in that each protrusion is provided with at least one transverse edge, and the shank is provided with a reciprocal groove. The blade according to claims 1 and 2, characterized in that the outer surface of the insert is inclined to the axis of the turbine at an angle not exceeding 90 °.
