Abstract
To reduce the number of stages of a turbine and, associated therewith, the overall length and the costs, blading having high stage-specific enthalpy transfer is to be used. In this case, the disadvantages of conventional highly loaded blading, such as increased secondary flow losses due to blades of large chord length and comparatively small height and the design of the turbine in the complicated chamber type of construction, are to be avoided. Resulting from these requirements is a highly loaded slim blade type of construction having considerable deflection. A turbine having blading according to the invention is characterized by a loading parameter RBL, which in the HRBL blading according to the invention, in contrast to conventional types of construction, is greater than 1.
