I agree, Avio doesn't mean EBM LPT blades. I do believe that Avio Cameri does mean EBM LPT blades. They could use laser technology but they've shown time and again EBM LPT production at Cameri.
I don't know whose turbine blades are in the engines that have been produced to date. I believe that CFM would want to test the LPT parts from ALL their suppliers to evaluate each under actual running conditions.
But this is what did bother me. Not in a bad way, just that I didn't understand what was really going on: Avio Aero CEO: GE Brings New Opportunities - Jun 15, 2015 We are also investing in our manufacturing facility at Bielsko-Biala, preparing a new production line for LEAP nozzles, something that will last for decades. With 1,000 engineers in its engineering center in Warsaw, GE has made Poland one of the company’s key partners.
I did make a little headway in understanding by making this connection: The winning product of the Polish Product of the Future Competition is a kit of nozzle vanes in the low pressure turbine for GEnx-2B engine. Project description: The winning product of the Polish Product of the Future Competition is a kit of nozzle vanes in the low pressure turbine for GEnx-2B engine. This is a crucial module of the engine which is responsible for propulsion of the compressor and has an impact on the life cycle of the engine and operational safety. Thanks to the innovative project of this part of the turbine, which is done by Polish engineers from the company Avio Polska and scientists from Polish universities, the fuel consumption of GEnx-2B will be approx. 15% less in comparison with the engines which are used nowadays. Moreover, at the same time the engine will emit less noise and will be more efficient.
Project innovativeness: The innovativeness of the nozzle vanes consists in the application of some new parameters for particular types of vanes in the kit where are used the most modern unique solutions of the field of aerodynamics.
The changes in arrangement of the nozzle vanes, their shape (including the shape of their edges) and inclination enable to reduce the number of components of the turbine which is connected with the decrease in the engine mass, production cost and increase in operational reliability. New solutions contribute also to the reduction of the fuel consumption compared to the engines which will be replaced by GEnx-2B and it enables the savings of each flight. The awarded project is a great progress in the field of aero-propulsion not only in national scale but also all over the world. There has been implemented innovative technologies of processing and new materials which has had a substantial impact on the highest quality achievement and guarantee longer life cycle of the engine.
While I still haven't seen hard information on how Avio Polska is involved in the LEAP engine I did find more information with their Polish Product of the Future Competition winner. Avio Polska is making low pressure turbine components. The technology is not explained. Best guess is that this technology will be used for production parts in the LEAP as well as the GEnx-2B engines. THE WINNERS OF THE 12th EDITION OF THE POLISH PRODUCT OF THE FUTURE COMPETITION 2008 Product Of The Future At The Pre-Implementation Stage Winner COMPLETE KIT OF STATOR VANES OF THE LOW PRESSURE TURBINEFOR THE GEnx-2B ENGINE Avio Polska Sp. z o.o. / Bielsko-Biala
Where do I find this good stuff? I look. Really, really, really hard. Everywhere.
