A machine vane unit includes a first airfoil and a second airfoil located between and connected to a first flange and a second flange. The second airfoil includes a second leading portion located rearward of a first leading portion of the first airfoil relative to a direction of intended flow. The first flange and the second flange are configured to be connected to casing for a machine portion. The first airfoil and/or the second airfoil may include and/or have cast therein a hollow. The first airfoil and the second airfoil may be formed integrally.
