We are currently looking for candidates to work in the Directorate of Technical and Quality Management onsite at ESTEC in the Mechanisms Engineering Department. You will lend support to the Agencys projects, technology research activities and evaluations of industrial contractors documentation and test verifications. Tasks and Responsibilities Fluid Structures, Vibroacoustic and Shock Modelling and Analysis You shall be responsible for the generation and setup of dynamic mathematical models for fluidstructure interaction effects, vibroacoustic and shock response for spacecraft, launchers and instruments of Agency funded projects using the Finite Element, the Boundary Element, and the Statistical Energy Analysis method where applicable, taking into account the specific objectives of such analyses for incompressible and compressible fluids. The above shall include but not be limited to tanks with without membranes, solar arrays, spacecraft subsystem and system models. Shall further perform the dynamic analysis modes, frequency transient acoustic responses shock responses, evaluate critically the results and issue relevant documentation covering all analysis steps Shall take into account the specific objectives of such analyses and where necessary nonlinear approaches shall be considered and specific solution sequences shall be developed Shall support the Agency in the definition and implementation of technology developments in this area aiming at enhancing relevant tools and methodologies Dynamic Test Data Analysis and Correlation You shall be responsible for the support to the Agency in operating analysis tools for the analysis of dynamic test data modal survey, frequency transient responses, shock responses for spacecraft launchers of Agency funded projects and comparison with analytical predictions Shall further perform where relevant modal identification of the test data, evaluate critically the results and make usage of these results for updating structural finite element models Shall perform where relevant, assessment of shock response data Shall take into account the specific objectives of such analyses and where necessary nonlinear approaches shall be considered and specific solution sequences shall be developed Shall issue relevant documentation covering all analysis steps. Where applicable you shall produce advanced reduced dynamic mathematical models Generation of Load Cases for Static and Dynamic Structural Dimensioning You shall be responsible for the generation and setup of load cases for static and dynamic structural analysis design and tests for Agency funded projects. Heshe shall make use of mathematical model responses, Launcher Coupled Analysis results, MultiBody Dynamics analysis tools, as well as test flight data and be familiar with spacecraft design practices. Heshe shall also evaluate critically the results and the loads and issue relevant documentation. Other tasks Support the activities of development contracts regarding the above areas, including direct interfaces with the prime contractors, participate in progress meetings and reviews, as requested, and provide appropriate feedback on the achieved progress and discussions Interfacing with the prime contractors, participate in progress meetings and reviews, as requested by project work, and provide appropriate feedback on the achieved progress and discussions Experience and Education Masters in mechanical or aeronautical engineering plus a minimum of 4 year working experience in the Space industry Several years of experience in the field of light structures dynamic behaviour and modelling, fluid structure interaction and vibroacoustic modelling You should have adequate knowledge in the relevant software, such as Nastran, Patran, Rayon, AutSEA, DynaWorks, SIMPACK, DCAP, FABE. Some experience with CAD software such as Catia5 would be an advantage. Additionally, some experience on fracture control and, in particular on fracture crack growth and fatigue analyses using ESACRACK and ESAFATIGUE would be an asset
