Beschreibung
Zusammenfassung:The turbine blade comprises an airfoil having opposite pressure and suction sidewalls extending from a platform to a free end tip and in a chordwise direction from a leading edge to a trailing edge. The blade has two winglets extending in a chordwise direction from adjacent the leading edge to adjacent the trailing edge. Each winglet extends from the pressure sidewall upwardly and outwardly from the sidewall to provide a channel between them. Each winglet has a free end extending laterally beyond a surface defined by the pressure sidewall offset.
