Highly loaded HPT blading in KTH test turbine - An attempt to reduce the number of blades in the first stage in a high pressure turbine
The main goal with this thesis was to investigate the possibility to reduce the number of blades in a high pressure gas turbine row. The reason for this study was the interest to reduce the amount of cooling air needed within the blade row by reducing the wetted area, hopefully without losing efficiency. Another reason for reducing the number of blades was to reduce the costs. A new design of an
