 Obiettivo del progetto (Objective)

'The goal of the project is design and manufacture a specific test bench dedicated to give more confidence of the design in term of reliability at components level and help the user to expertise and to validate the minimum life expectation of future aircraft power electronics converters. Endurance Tests and Reliability Prediction of avionics is a critical part of the development of on-board electronics. For this purpose Test systems must be implemented that can deliver realistic functional and environmental conditions that allow to test and age components in use and in extreme environmental flight conditions. Traditionally this has been done by means of ATE systems for the functionality tests and with electrodynamic shaker systems and dynamic or thermal shock climatic chambers. In advanced test systems, all three elements are combined into one system, being able to test the functionality of the onboard electronics under extreme environmental conditions. This proposal describes a state of the art test system that will allow onboard electronic designer validate their prototypes or series hardware by means of using a test rig that ages the hardware in extreme environmental conditions. The innovative character of the proposal comes from relevant aspects of all three main components and their also from their integration.'

Introduzione (Teaser)

Increasing electrical control of traditionally hydraulic and pneumatic systems could make the friendly skies a lot quieter and aeroplanes much more reliable. A novel power electronic modules test bench integrating three tests in one will spur development.

Descrizione progetto (Article)

More-electric aircraft (MEA) is an emerging design concept on the road to future all-electric aircraft. An aeroplane's non-propulsion functions such as raising and lowering the landing gear are transitioning to electric power rather than the current hybrid of hydraulic, pneumatic, mechanical and electrical.

Owing to MEA's huge potential to reduce the aviation industry's carbon footprint and costs while enhancing efficiency and safety, Europe's aviation industry has been collaborating closely in this area of research. With financial support from the EU, the 'Test bench for endurance test and reliability prediction of avionics power electronic modules' (AERTECVTI) project developed a multi-components test bench to put MEA's power electronic converters through their paces.

The bench simulates realistic extreme conditions of temperature, humidity and vibration, and can run steady-state and transient test modes. It integrates three conventional test systems in one to test the reliability of the on-board power electronics (components and converters level).

AERTECVTI houses a climatic chamber, a vibration test system and an electrical characterisation bench test. Thanks to its large size and electrical connectivity, the test bench can control and monitor up to 25 components simultaneously. To maximise user friendliness, there is also a graphical user interface to control, monitor and combine several parameters.

Scientists have provided the means to enhance efficiency and reliability of verification and qualification of future aircraft power electronics converters in a severe multi-constrained environment according to DO-160E. AERTECVTI technology will support designers in selecting system architectures that best meet customer needs in a knowledge-based way. It will also significantly shorten the design cycle and related costs for a major boost to competitiveness. AERTECVTI outcomes will thus be a critical step on the road to MEA.
