Systems for Green Operation (SGO) WP1 delivered a V&V Plan on how European industry can support and de-risk Airbus in their work in SGO WP4 on a comprehensive ground demonstration ahead of a flight demo. This de-risk and support also included inputs from SGO WP2.3 on Technology Adaptation.
ELPOC directly supported Airbus in SGO WP4.2 Ground Demonstration. SPUK made extensive use of technology development hardware, engineering capabilities and facilities from previous R&T projects, principally EU MOET, UK AMES.
SPUK worked with Airbus throughout ELPOC’s planned 51 months duration. In its initial stages the project had a Preliminary Design Review (PDR) addressing the Architecture Options available (power system 230VAC VF, +/-270VDC – generation, conversion, usage; emulation of major electrical loads including a programmable inertia rig for engine start and icing protection technologies).
SPUK set up a basic emulation of an aircraft essential power buss and used this as an environment to conduct a series of specific trade off studies in key power electronic control technologies – to progress the Airbus activity on top level power system optimisation for a complete aircraft. The PDR determined a definitive list of these key electronic technologies. SPUK proposed: Power Density (kW/kg); Efficiency; Switching Strategy; Control Strategies; Topology of Transistor/Diode Options; Forced Air Cooling (deletion of liquid circuit).
The ELPOC project investigated architecture options that can be optimised by power electronic controls and electrical system technology; it develops these technologies through sub-system and system testing prior to integration into an aircraft systems rig.
In the time frame of this programme a large (200kVA) new technology starter generator and its associated power electronics were design manufactured and tested in order to mitigate the technological risks in the way of the more electrical aircraft availability.
