Zusammenfassung:	An airfoil includes: an airfoil body extending from a radially inner root portion to a radially outer tip portion, extending from a pressure side to a suction side, and from a leading edge to a trailing edge portion. The trailing edge portion includes: a linear pressure side portion; a linear suction side portion; a trailing edge tip portion; and at least one elliptical portion disposed between the trailing edge tip portion and at least one of the linear pressure side portion and the linear suction side portion. The trailing edge portion may also include a circular trailing edge tip portion.
