Claim 13:
14. An airfoil assembly for a turbine engine, the airfoil assembly rotatable about a rotational axis and comprising:
a platform having an upstream edge and a downstream edge, with a platform surface extending therebetween, with at least a portion of the platform surface extending along a platform surface baseline defined by a constant radial height from the rotational axis;
a pair of circumferentially adjacent airfoils, with each airfoil of the pair of circumferentially adjacent airfoils having an outer wall extending between a leading edge and a trailing edge and between a root and a tip in a span-wise direction a total length between the root and the tip, the outer wall defining a pressure side and a suction side and the root provided along the platform surface at the platform surface baseline;
a projection provided along a portion of the platform surface and against the outer wall of a corresponding airfoil of the pair of circumferentially adjacent airfoils, the projection extending radially outward from the platform surface baseline;
a splitter provided along a portion of the platform circumferentially between the pair of circumferentially adjacent airfoils, the splitter extending radially outward from the platform surface baseline; and
a valley provided along the platform surface and extending radially inward from the platform surface baseline to a maximum depth, the valley being located entirely between the splitter and the suction side of the corresponding airfoil.
