Title (EN) LEADING EDGE COOLING CHANNEL FOR AIRFOIL
(FR) CANAL DE REFROIDISSEMENT DE BORD D'ATTAQUE POUR SURFACE PORTANTE
Abstract: front page image
(EN)Methods and systems of cooling airfoils are provided. The present invention provides systems and methods for providing cooling channels located within walls of a turbine airfoil. These cooling channels include micro-circuits that taper in various directions along the length and width of the airfoil. In addition, these cooling channels have a variety of shapes and areas to facilitate convective heat transfer between the surrounding air and the airfoil.
(FR)La présente invention concerne des procédés et des systèmes de refroidissement de surfaces portantes. La présente invention concerne des systèmes et des procédés permettant de fournir des canaux de refroidissement situés à l'intérieur des parois d'une surface portante de turbine. Ces canaux de refroidissement comprennent des micro-circuits qui se rétrécissent dans différentes directions sur la longueur et la largeur de la surface portante. En outre, ces canaux de refroidissement ont une grande variété de formes et des superficies pour faciliter le transfert de chaleur par convection entre l'air environnant et la surface portante.
