Abstract
Disclosed is an airfoil array segment () of an airfoil array for a turbomachine, the airfoil array segment including a platform () having a platform surface, as well as at least two airfoils (). The platform surface has a depression () which extends up to the first airfoil and contacts the pressure side () of the first airfoil downstream of 80% of the axial chord (g) downstream of the leading edges () and which contacts the pressure side () of the first airfoil downstream up to no more than 80% of the axial chord (g) downstream of the leading edges (). At least one lowest point () of the depression is located at least 90% of the axial chord (g) downstream of the leading edges (). Also disclosed are an airfoil array, an airfoil passage, a platform, a turbomachine, and an aircraft engine.
