1. A blade comprising:
a platform; and at least one root configured to be connected to a blade carrier, wherein airfoil portions extend from opposite circumferential sides of the platform, each airfoil portion defining an operating surface being a surface facing the other airfoil portion, wherein an operating surface of one of the airfoil portions defines a suction side and the other operating surface of the other airfoil portion defines a pressure side, wherein, when assembled, the two airfoils portions of the blade and another blade adjacent thereto and connected to each other together define an airfoil, and wherein the airfoil portions each extend to a trailing edge of the airfoil and define a gap between a facing edge at the corresponding trailing edge, respectively, the gap extending the length of the trailing edge of the airfoil. |
