Claims (5)

1. Подвижная лопатка турбины высокого давления турбомашины, содержащая, по меньшей мере, один охлаждающий контур, который образован, по меньшей мере, одной полостью (24), проходящей радиально между вершиной (16) и основанием (14) лопатки (10), по меньшей мере, одним впускным отверстием для воздуха на одном радиальном конце полости или полостей для подачи охлаждающего воздуха в охлаждающий контур или контуры, и несколькими выпускными щелями (26), открытыми в полость или полости и выходящими на выходную кромку (20) лопатки, причем выпускные щели расположены по длине выходной кромки между вершиной и основанием лопатки по существу перпендикулярно продольной оси (Х-Х) лопатки, отличающаяся тем, что, по меньшей мере, одна выпускная щель (28), ближайшая к основанию пера лопатки, выполнена с наклоном к вершине лопатки под углом от 10 до 30° к оси вращения лопатки.1. A moving blade of a high pressure turbine of a turbomachine, comprising at least one cooling circuit, which is formed by at least one cavity (24) extending radially between the top (16) and the base (14) of the blade (10), at least one air inlet at one radial end of the cavity or cavities for supplying cooling air to the cooling circuit or circuits, and several outlet slots (26) open into the cavity or cavities and extending to the outlet edge (20) of the blade slots located wife along the length of the outlet edge between the top and base of the blade essentially perpendicular to the longitudinal axis (XX) of the blade, characterized in that at least one outlet slot (28) closest to the base of the feather blade is made with an inclination to the top of the blade at an angle of 10 to 30 ° to the axis of rotation of the scapula. 2. Лопатка по п.1, отличающаяся тем, что наклон выпускной щели (28), ближайшей к основанию пера лопатки, составляет примерно 20°.2. The blade according to claim 1, characterized in that the inclination of the outlet slit (28) closest to the base of the feather blade is approximately 20 °. 3.

The blade according to claim 1 or 2, characterized in that the upstream end (28a) of the outlet slit (28) closest to the base of the blade feather is formed essentially in the transition zone (30) between the base of the blade feather and the shelf (22 ) forming a partition for the passage of the flow of combustion gases through the high pressure turbine. 4. Лопатка по п.3, отличающаяся тем, что острые углы переднего по потоку конца (28а) выпускной щели (28), ближайшей к основанию пера лопатки, зашлифованы.4. The blade according to claim 3, characterized in that the sharp angles of the upstream end (28a) of the outlet slit (28) closest to the base of the blade blade are sanded. 5. Турбина высокого давления турбомашины, отличающаяся тем, что она содержит несколько подвижных лопаток (10) по любому из предыдущих пунктов.5. High pressure turbine of a turbomachine, characterized in that it contains several movable blades (10) according to any one of the preceding paragraphs.
