CONCLUSIONS This document represents an "RTGD" engineering tool that aims to get a fast design of a radial turbine. Loss models have been implemented to predict the radial turbine overall performance with a rotor geometry optimization. Despite limited data available in the literature, RTGD has been validated using a real radial turbine test case, in addition a code-to-code comparison has been made. In the cases examined it is known that the passage loss represents the highest loss. From the comparison with the NASA RIFTUD code, the RTGD tool has proved easier to use by providing more complete results. The generation of the rotor 3-D geometry is currently under development, to carry out a further optimization through CFD analysis. In conclusion, the tests carried out were useful to understand the RTGD reliability for a future application in the aerospace propulsion field. The latter one will be integrated into Concurrent Design Facility (CDF), aimed at design all different components of the entire rocket-engine. REFERENCES 1.
