BLADE FOR A TURBO DEVICE WITH A VORTEX-GENERATOR

摘要

The invention relates to a blade construction for a turbo device, preferably a blade array of a low-pressure turbine, on the inlet-side profile surface of which a vortex generator is arranged downstream of the speed maximum. The vortex generator is formed by a surface undulation with at least one wave, the wave back of which runs in the form of a wave trough and/or wave peak in the blade vertical direction.
