Abstract (en)
[origin: US4571937A] A muilti-stage turbine having shrouded turbine blades which has a stationary guide grid arranged between the rotor shroud and the turbine casing. By virtue of the construction of the guide grid, leakage and cooling air (escape air) of the rotor blade can be adapted to the low whirl of the main stream passing through the rotor to effectively prevent misaligned entry into the following turbine stage.
