1. An airfoil array for a gas turbine engine comprising:

  • a plurality of airfoils spaced circumferentially apart from each other about an engine center axis, each airfoil being associated with a platform;

    an endwall extending circumferentially about the engine center axis, the endwall being defined by adjacent platforms, and wherein each pair of adjacent platforms are separated from each other by a gap; and

    an endwall contour shape defined to extend from a first location on one side of the gap to a second location on an opposite of the gap, and wherein the endwall contour shape is the same for all adjacent platforms.
