For the Ultra-High Propulsive Efficiency (UHPE) Demonstrator for SMR aircraft (WP2), the technology maturation has successfully completed the tests plan and demonstrated high TRL achievements on the studied technologies. The engine Ground Test Demonstrator has successfully completed the Concept Design Review phase and entered into the preliminary design maturity phase.
For the Business Aviation / Short Range Regional Turboprop Demonstrator (WP3), the Tech TP demonstrator, completed full ground demonstration of hybridized functions. The final acoustic evaluation of 7-blades propeller by indoor test was completed. After successful TechTP tests completion, the engine emissions savings performances were confirmed for SAT application, and benefits of hybrid electric configurations have been assessed at engine level.
For the Advanced Geared Engine Configuration (WP4), Aero engine compression- and expansion system technologies were tested and validated in two WP4 demonstrator programmes, namely the Engine Material VALidation (EMVAL) demonstrator and the 2-Spool Compressor Rig (2SCR). Both demonstrator vehicles are aiming for the improvement of the 2nd generation of future GTF engines.
For the Very High Bypass Ratio (VHBR) Middle of Market Turbofan technology (WP5). The new coupled models for realistic bearing chamber geometry were developed and ran robustly on Ultrafan® geometries. Work on the bearing oil shedding droplet velocities and measurement of wall film thickness is completed. The High-Pressure Turbine Rig Phase 2 Measurement campaign commenced in 2023. The Test Readiness Review (manufacturing strut casing) is complete and phase 2 is complete.
For the Very High Bypass Ratio (VHBR) Large Turbofan Demonstrator (WP6). Work commenced on the UltraFan® to align the instrumentation parameters to the test bed which completed in mid-March 2023, the commissioning phase commenced in April 2023. A summary of the first testing was reported in Mid-May 2023. The successful run of UltraFan® technology demonstrator to maximum power was achieved in Testbed 80 in Q4 2023. Final activity for test data analysis and reporting are finalised for the Intermediate Pressure Turbine Module and ICC.
For the Reliable and more efficient operation of small turbine engines (WP8), the hybrid electric propulsion system has been evaluated for SAT application, the airframer proceed in updating the architecture to evaluate the most suitable configuration. No further technologies development has been carried out within 2022 but the studies at propulsion system level has been summarized and evaluated. Test campaign on combustor have been finalized.
For the Engine Eco Design (WP9), all detailed Life Cycle Inventory (LCI) data were collected and provided to ECO TA through analysis performed on demonstrators parts, assessing the impact of a range of selected technologies: Additive Manufacturing, Re-use & Recycling of carbon fibers, Advanced Engine Manufacturing Processes and Maintenance and Repair activities.
