Title (EN) GAS TURBINE COMPONENT WITH COOLING HOLES
(FR) ÉLÉMENT DE TURBINE À GAZ DOTÉ DE TROUS DE REFROIDISSEMENT
Abstract:
(EN) A gas turbine component (1) is described, comprising a main 5 body (80) having a front surface (77), a rear surface (78) and at least one through hole (81) extending from the front surface (77) to the rear surface (78), the through hole (81) having a hole inlet (86), a hole outlet (87) and a central axis (82), which preferably runs normal to the front surface 10 (77). The component comprises a perforated plate (83), comprising a flat portion (96), which is positioned at the rear surface (78) and connected to the rear surface (78) of the main body (80), and at least one formed perforation (97) comprising a perforation outlet (88), the formed perforation 15 (97) being positioned at the hole outlet (87) and forming a flow channel from the hole outlet (87) to the perforation outlet (88), the perforation outlet (88) having a central line (79), wherein the central line (79) of the perforation outlet (88) and the central axis (82) of the through hole 20 (81) include an angle Į between 40° and 90°.
(FR) L'invention concerne un élément (1) de turbine à gaz, comprenant un corps principal (80) ayant une surface avant (77), une surface arrière (78) et au moins un trou traversant (81) s'étendant de la surface avant (77) à la surface arrière (78), le trou traversant (81) ayant une entrée (86) de trou, une sortie (87) de trou et un axe central (82), qui s'étend de préférence perpendiculaire à la surface avant (77). L'élément comprend une plaque perforée (83), comprenant une partie plate (96), qui est positionnée au niveau de la surface arrière (78) et reliée à la surface arrière (78) du corps principal (80), et au moins une perforation (97) formée comprenant une sortie (88) de perforation, la perforation (97) formée étant positionnée au niveau de la sortie (87) de trou et formant un canal d'écoulement de la sortie (87) de trou à la sortie (88) de perforation, la sortie de perforation (88) ayant un axe central (79), l'axe central (79) de la sortie (88) de perforation et l'axe central (82) du trou (81) formant un angle Į entre 40° et 90°.
