All key elements of the system architecture and key interfaces are defined, system level requirements are fixed and aligned with project ambition and Aircraft requirements and sufficient to start decompostion to system component level and development of subsystems.
All components are designed, developed and ready for integration into the subsystems to enable functional validation on subsystem level. Testing infrastructure in place to validate individual subsystems.
Subsystem validation finished and integrated into the complete propulsion system demonstrator. Ready for system level integration testing to validate overall system functionality and performance.
All the subsystems integrated into the final demonstrator and the final system is ready for safe operation and final validation.
The overall integrated system demonstrator functional testing complete. Performance characterization testing complete.
