N2 - In this paper we analyse numerically how the tip-leakage vortex in a linear cascade is impacted by transonic flow in general and by compression shocks in particular. We show that, despite higher blade loading and consequently stronger tip-leakage vortices, the axial-momentum deficit in the tip region decreases for transonic flow conditions. In addition, the overturning induced by the tip-leakage vortex decreases for transonic flow conditions. Both effects can be regarded as highly favourable when the potential reduction in boundary-layer separation in downstream diffusers or intermediate ducts is considered.
