Abstract
Described are an airfoil array segment () having at least two airfoils () and a platform () that features an axis asymmetrical platform surface (). This platform surface features an elevation () that extends from the pressure side () of the first to the suction side () of the second airfoil (). A highest point () of the elevation is more proximate to the suction sideof the second airfoil () than to the pressure side () of the first airfoil (). Also described are an airfoil, a platform, an airfoil passage and a turbomachine.
