1. Aerothermal Study of Intermediate Turbine Ducts
Abstract : An intermediate turbine duct guides the flow from the smaller diameter high pressure turbine to the downstream larger diameter intermediate or low pressure turbine. It is typically equipped with a structural vane transferring loads for the core to the external parts, and supplies the core with necessary services such as oil and air. READ MORE

2. Flow Control and Shape Optimization of Intermediate Turbine Ducts for Turbofan Engines
Abstract : Demands on improved efficiency, reduced emissions and lowered noise levels cause a strive towards high by-pass ratios of commercial turbofan engines. This results in an increased radial offset between the high- and low-pressure turbines. Thus the design of the intermediate turbine duct connecting the two turbines becomes more challenging.

3. Aerothermal Investigation of an Intermediate Turbine Duct
Abstract : Intermediate turbine ducts are used to guide the flow in turbofan engines from the short-radius high-pressure turbine to the large-radius low-pressure turbine. The demand for more efficient and silent jet engines and with a reduced environmental impact requires turbofans with increasingly higher by-pass ratios. READ MORE

4. A Large-Scale Facility for Investigation of Intermediate Turbine Ducts: Design, Implementation and Initial Tests
Abstract : Intermediate turbine ducts are used in modern multi-spool jet engines for guiding the flow from the high-pressure turbine to the low-pressure turbine. The demand for lighter, more efficient and more environmentally friendly aircraft engines requires the new jet engines to have higher by-pass ratios. READ MORE

5. Experimental investigation of the flow field in an aggressive intermediate turbine duct
Abstract : Intermediate turbine ducts are used for connecting thehigh-pressure turbine to the low-pressure turbine in turbofan engines. In order to meet the demands for more efficient and environmentally friendly jet engines, future intermediate turbine ducts need to have larger radial off-sets without increasing their length.
