Abstract

Design, Development and Analysis of a Contra-Rotating Turbine will be carried out and a suitable experimental test rig will be built to test the performance of the Contra-Rotating Turbine and to carryout detailed flow measurements. This design of Contra-Rotating turbine will be carried out for small gas turbine application of two spool configuration. A contra-rotating turbine can have blade rows that are joined to two shafts rotating in opposite direction. This configuration eliminates the presence of stators in comparison to conventional turbines thereby decreasing the weight and axial length of the turbine and increasing the efficiency due to reduction of losses in the stators. This leads to better thrust/weight ratio engines.
