Contouring of an airfoil array platform

An airfoil array segment of an airfoil array for a turbomachine, the airfoil array segment comprising:

• a platform having a platform surface, a first airfoil and a second airfoil, the first and second airfoil defining, on the platform surface, axial chords of the first airfoil and the second airfoil between respective leading and trailing edges, and defining an inter-airfoil strip between the pressure side of the first airfoil and the suction side of the second airfoil;
• wherein the platform surface has a depression extending up to the first airfoil, the depression having at least one lowest point located at least 90% of the axial chord of the first airfoil downstream of the leading edges, and the depression contacting the pressure side of the first airfoil downstream of 80% of the axial chord of the first airfoil downstream of the leading edges and contacting the pressure side of the first airfoil downstream up to no more than 80% of the axial chord of the first airfoil downstream of the leading edges.
