This proposal first aim is to present Akira Technology scientific and technical solution in order to improve both exhaust gases related measurements system reliability and maintenance. We have taken into account all specific demands expressed in the Topic sheet (compactness, tightening, sealing, thermal stress, cooling, maintenance). There are two linked innovative characters in our proposal. Topic Leader proposes an innovative architecture by positioning the measurement system displacement sub-assembly upstream the combustor. Akira proposal innovative character rely on using rotating sealing rings to allow this new architecture designSecondly, we will demonstrate that Akira is able to provide such complete solution thanks to its technical and scientific knowledge, know how, strategy, organisation and cost management abilities.To conclude, it is important to underline that such solution will improve both quality measurement and system reliability. This innovative solution will allow easy and quick maintenance as well as system adaptability on any other bench. From an economic point of view, such design would have many applications in small gas turbine development test and Akira will increase European competitiveness by becoming an exhaust gas measurement system provider.
