Periodic Reporting for period 2 - BIRAN (IP TurBIne Rear Stage Aero/Noise Rigs)

Período documentado: 2019-01-01 hasta 2019-12-31

Resumen del contexto y de los objetivos generales del proyecto

The BIRAN project targets the environmental and competitiveness challenge of the European aeronautics sector, by addressing the topic of experimental validation rig testing to develop aerodynamic and acoustic technologies for the rear stages of VHBR IP turbines.

The advancement of IP Turbine technologies, as an important contributor to the VHBR engine concept, will participate significantly to the global objectives from Clean Sky2, which aim towards achievement of ACARE flightpath 2050 ambitious goals about CO2, NOx and Noise emissions.

The global objectives of this project are aligned with the targets marked by Rolls-Royce for the Middle of Market Technology configuration. This project will deliver individual improvements in sub-system technology developments, to support the overall development of system level technologies capable of delivering substantial reductions in emissions.

The specific objectives of CTA as partner, include all the tasks to permit the experimental validation of relevant technologies (i.e. design, instrumentation, manufacturing, assembly, testing and supply of all test data). BIRAN Project is focused on the activities to develop and test a multistage rig of the rear stages, comprising all the aerodynamic and acoustic technologies individually developed in ORBIT project, in order to characterize how these technologies interacts, and therefore to validate them in a further TRL.

The results will be compared with a relevant reference rig test, as an opportunity to integrate the new knowledge and enable the application of the innovations.

To guarantee the success of BIRAN project, it is required to develop European world-class test capability that includes the acquisition of testing and measurement technologies. Experience from the participation in previous R&T European programmes is key to minimize program risks and deliver successfully rig testing in the required time scales.

Finally, the BIRAN Project considers activities for the dissemination and exploitation of the results to maximize the expected impact on competitiveness.

Trabajo realizado desde el comienzo del proyecto hasta el final del período abarcado por el informe y los principales resultados hasta la fecha

Definition of a multistage rig representative of the rear stages of VHBR IP turbines has been completed. The work performed includes all the design activities that are necessary to accomplish test objectives, such as the detailed mechanical design of all the parts, including those required to adapt the rig to the test facility, mechanical assesment and hardware procurement. A full definition of instrumentation is as well available, to be used in the rig test to validate the aerodynamic and acoustic technologies required by the last stages of VHPR IP Turbine.

Multi stage rig assembly and installation in the transonic wind tunnel facility have been completed during the second period. Detailed measurements of aerodynamic characterization and noise performance have been acquired during test campaign, to accomplish the experimental validation of aerodynamic and noise technologies required by the last stages of VHBR IP Turbine.

The development of multi-stage IPT technologies, as an important contributor to the UltraFan engine concept, will significantly contribute to the global objectives of Clean Sky 2, which aim towards the achievement of ACARE Flight-Path 2050 ambitious goals of reducing CO2, NOx and Noise emissions.

Avances que van más allá del estado de la técnica e impacto potencial esperado (incluida la repercusión socioeconómica y las implicaciones sociales más amplias del proyecto hasta la fecha)

Main added value to present state-of-the-art is the development of the specific aerodynamic and aeroacoustic technologies required for the rear stages of IP turbine for the VHBR engine applications.

Differences of this new turbine configuration compared to those used in current state-of-the-art civil large turbofans, are more than remarkable. The main technical challenges are related to the increment in rotational speed and the turbine entry temperature.

Aerodynamic and aeroacoustic technologies required to design an efficient and low-noise turbine for the new high demanding architecture, are not currently available. The validation of these technologies up to TRL 5 proposed in BIRAN project, will enable to advance beyond the state-of-the-art for the new VHBR engines

Among Clean Sky 2 programme all the Engine ITD demonstrators and technologies are the most important contributors to the CO2 emission reduction aimed in H2020. This project is specifically focused on development of aerodynamic and aeroacoustic technologies, that will reduce CO2 , SFC and noise emissions.

The technologies that will be ultimately deployed from the results obtained in BIRAN Project, will ensure that Europe retains a fully competitive large civil engine capability.

In the last decades European aviation has successfully risen to a world leader through the combined efforts of public and private European entities, including major companies, SMEs as well as academia and research laboratories. Even though the global aviation market is increasing, Europe must ensure the continued success and economic contribution of its aviation industry by investing continuously and heavily in key enabling concepts, technologies and systems.

BIRAN project will provide innovative experimental capabilities to explore and understand the enabler technologies associated to the challenges of the VHBR IP turbine within the new engine architecture, that will contribute to achieve European engine industry competitivness objectives by developing enabling technologies towards cleaner and quieter aircraft according to the Flightpath 2050 goals.
