GAS TURBINE STATOR WITH WINGLETS

摘要

A stator airfoil of a gas turbine engine according to one embodiment includes at least two winglets projecting transversely from opposed sides of a stator airfoil, respectively. Each winglet includes a leading edge axially and outwardly extending from one of the opposed sides of the stator airfoil and a trailing edge extending from the stator airfoil to join with the leading edge of the winglet. The winglets therefore provide a wide trailing edge thereof to aerodynamically manage boundary layers and micro-shocks of a working fluid.

1. A stator of a gas turbine engine, the stator comprising: a stator airfoil having leading and trailing edges and opposed pressure and suction sides extending between the leading and trailing edges; at least two winglets projecting transversely from the respective opposed pressure and suction sides of the stator airfoil, the winglets configured to generate an aerodynamic load on the stator airfoil and each including a winglet leading edge extending axially and outwardly from the corresponding pressure or suction side of the stator airfoil and a winglet trailing edge extending from the stator airfoil to join with the winglet leading edge.
