Our main objectives in using TURBOdesign1 were based on our qualitative and quantitative requirements to improve our design system. Our main qualitative objectives were:
- Revise the conventional design process based on 2D sections geometry generation with a novel one outputting immediately the 3D turbine shape
- Eliminate most of the loops between design and analysis phases and optimize aerodynamically the air foils in terms of blade loading and mach number levels and balancing them from hub to tip
This was particularly important since the high-lift turbine blades concept was going to be extensively used and applied in the new turbine projects and the possibility to explore quickly a large population of design solutions was greatly appreciated.
Our quantitative objectives in using TURBOdesign1 in design of LP turbine blades were mainly related to:
- Lower the “engine specific fuel consumption (sfc)” by improving the whole turbine thermodynamic efficiency
- Save at least 30% of the engineering time or reverse it in optimizations loops
Initially TURBOdesign1 was validated extensively by using 3D CFD codes and it was then integrated into the design system at Avio. By using TURBOdesign1 we have been able to achieve most of our objectives to improve our design system and shorten engineering and development time. A number of Avio products have since been designed by using the 3D Inverse Design technology.
