Periodic Reporting for period 3 - IOVISTAS VIRTEST (INPUTS OUTPUTS VIRTUAL INTEROPERABLE SIMULATION TEST OF AVIONICS SYSTEMS IN VIRTUAL/HYBRID/REAL TESTBENCH) Reporting period: 2021-06-01 to 2022-10-31 Summary of the context and overall objectives of the project The aim of IOVISTAS VIRTEST project is to contribute to achieve the major expectations from More Electric Aircraft and consequently for reducing fuel consumption, by developing an innovative virtual testing methodology for on ground test facilities dedicated to High Voltage direct Current integration. The project will allow avoiding difficulties related to physical test benches used in aircraft development process, which are complex platforms with high initial and recurring costs. They are usually on the critical path on the development and cannot be easily multiplied to increase the validation capacity.In particular, the facilities and equipment proposed will be used to test on ground actuation systems of electromechanical actuated surfaces such as ailerons, flaps, spoiler and winglet proposed by the Topic Manager in the context of Clean Sky 2 Regional FTB2 demonstrator, following the technology validation process before the aircraft integration.In this context the general objective of IOVISTAS VIRTEST project is the design, development and installation of a configurable virtual/hybrid/real ground test environment, aircraft and airframe representative, according to VISTAS EUROCAE standard for on-ground tested validation (up TRL5 of technology integration of airframe) of flight control surfaces driven by electromechanical actuators powered by high voltage DC electrical generation (HVDC).This general objective is twofold:• To develop an A/C representative electrical test installation composed by the HVDC part of the A/C electrical generation and distribution system.• To develop the I/O box concept, in accordance with VISTAS protocol, in order to provide the necessary interconnection between real and virtual test environments, and providing the necessary infrastructure for virtualization at FTB#2 actuation on-ground rig.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far) The main objectives of IOVISTAS VIRTEST project are to develop an aircraft representative test installation composed by the High Voltage Direct Current (HVDC) part of the aircraft electrical generation and distribution system and to develop the I/O box concept in accordance with VISTAS protocol in order to provide the necessary interconnection between real and virtual test environments. Virtual testing approach is the future and innovative solution to avoid the difficulties related to physical test benches used in aircraft development process, which are complex platforms with high initial and recurring costs. They are usually on the critical path on the development andcannot be easily multiplied to increase the validation capacity.More specifically the results of the project will improve the testing technology for new electrical system for Regional FTB2 demonstrator (which is based to the Topic Manager turboprop aircraft with high wing configuration thrusted by two turboprops). In particular the mail impact the developments to be achieved in this project will allow:• To improve fuel consumption due to a more efficient power transfer and usage.• To improve power generation capabilities due to a better energy management.• To avoid difficulties related to physical test benches which are complex platforms with high• initial and recurring costs.• To detect early in time failure modes of electrical equipment.• To avoid huge costs in terms of benches simplicity and wiring.• To anticipate safe behaviour. iovistas-box-architecture.png arquitectura-vistas.png
