At the Paris Air Show in 2009 Liebherr Aerospace & Transportation and Thales Avionics Electrical Systems announced a memorandum of agreement covering a range of business and technological initiatives in the field of power-optimized aircraft. The first joint research project is being showcased here in the form of a mock-up of the GETI test platform.
Part-funded by the French civil aviation authority, GETI (Gestion dynamique de la puissance Electrique et de la gestion Thermique) is a test stand that integrates electrical and thermal power consumers. It was recently installed at Liebherr Aerospace’s Toulouse facility and combines elements supplied by the two partner companies, plus Sonaca from Belgium. Thanks to its generic open architecture, the test platform can represent a wide range of commercial aircraft and its smart power management capabilities allow it to replicate and monitor the dynamic behaviors of both electrical and thermal loads during a flight mission profile.
Among other features, GETI is able to simulate the concept of a power module, with one system being used for different electrical loads. For instance, it can be used for either the air-conditioning pack or for the starter generator. It also simulates global thermal management techniques. Using GETI the management of both electrical and thermal loads can be optimized, allowing the development and validation of approaches that couple the two aspects.
Ultimately GETI is a tool in the drive to rationalize and optimize electrical consumption, cooling needs and overall system weight. The results are contributing to efforts to meet environmental objectives laid down by the Advisory Council for Aeronautics Research in Europe to greatly reduce CO2 and NOx emissions.
