OBTUSE ANGLE CHEVRON TRIP STRIP
An airfoil includes a cooling air passage for receiving a cooling air flow. A chevron including a first rib and a second rib extends from a common tip is disposed within the cooling passage for generating a turbulent flow to improve heat transfer. The chevron includes an angle between the first rib...

| description | An airfoil includes a cooling air passage for receiving a cooling air flow. A chevron including a first rib and a second rib extends from a common tip is disposed within the cooling passage for generating a turbulent flow to improve heat transfer. The chevron includes an angle between the first rib and the second rib that is greater than 90 degrees.
L'invention concerne un profil aérodynamique comprenant un passage d'air de refroidissement pour recevoir un flux d'air de refroidissement. Un chevron comprenant une première nervure et une seconde nervure s'étendant à partir d'une extrémité commune est disposé à l'intérieur du passage de refroidissement pour générer un écoulement turbulent pour améliorer le transfert thermique. Le chevron comprend un angle entre la première nervure et la seconde nervure qui est supérieur à 90 degrés. |
