Abstract (en)

[origin: US4470755A] A guide blade set for diverging jet streams in a steam turbine which has blades (2, 2') whose concave and convex surfaces are orthogonal firstly to the jet stream floor plate (3) and secondly to the jet stream passage ceiling plate (4) at their respective ends. Efficiency is improved by reducing losses in the neighbourhood of the jet stream ceiling plate.
