TURBOMACHINE ROTOR BLADE HAVING A VARIABLE ELLIPTICAL TRAILING EDGE

A rotor blade (100) of a turbomachine (10) includes an airfoil (114). The airfoil (114) includes a root (118) and a tip (115) which define a span (128) of the airfoil (114) therebetween. The airfoil (114) also includes a leading edge (124) and a trailing edge (126) downstream of the leading edge (12...

Beschreibung
Zusammenfassung:	A rotor blade (100) of a turbomachine (10) includes an airfoil (114). The airfoil (114) includes a root (118) and a tip (115) which define a span (128) of the airfoil (114) therebetween. The airfoil (114) also includes a leading edge (124) and a trailing edge (126) downstream of the leading edge (124) along a flow direction. The leading edge (124) and the trailing edge (126) each extend across the span (128) of the airfoil (114) from the root (118) to the tip (115). The airfoil (114) further includes a pressure side surface (120) and a suction side surface (122). The pressure side surface (120) and the suction side surface (122) are continuous about the trailing edge (126) and collectively define an arc (210) centered on the trailing edge (126). The arc (210) has a semi-major axis (206) and a semi-minor axis (204). The semi-major axis (206) and the semi-minor axis (204) of the arc (210) define an axis ratio, and the axis ratio varies over the span (128) of the airfoil (114).
