"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."
