ESTEC 15 December 2013<br />
Overview of the Division’s mission<br />
The <strong>Structure</strong>s <strong>and</strong> <strong>Mechanisms</strong> Division is the centre of competence of the Agency in all areas related to<br />
spacecraft <strong>and</strong> launcher structures <strong>and</strong> mechanisms. This encompasses spacecraft <strong>and</strong> launcher lightweight<br />
structures, stable structures, advanced mechanical materials applications, structural dynamics, damage<br />
tolerance, deployable structures/booms, active structures, hold-down <strong>and</strong> release devices, electrical motors<br />
for space mechanisms, launcher <strong>and</strong> re-entry hot <strong>and</strong> cold structures, l<strong>and</strong>ing attenuation systems, seals,<br />
valves, parachute systems, separation systems, reaction wheels, gyros, bearings <strong>and</strong> tribology aspects. It<br />
provides support to projects, preparatory programs <strong>and</strong> technology programs.<br />
Within this frame, the <strong>Mechanisms</strong> Section is in charge of all mechanisms engineering aspects, <strong>and</strong> the<br />
<strong>Structure</strong>s Section is in charge of all structural engineering aspects.<br />
<strong>Mechanisms</strong> <strong>Engineering</strong>:<br />
Overview of the field of activity proposed<br />
The Trainee will participate in the development <strong>and</strong> verification of mechanisms for use in space projects.<br />
In assistance to <strong>ESA</strong> engineers working in this domain, the holder of the training position will be given a<br />
specific task which may include:<br />
1. assistance in the implementation <strong>and</strong> monitoring of R&D contracts;<br />
2. critical review of design / analysis / test activity <strong>and</strong> simulation / characterisation / validation up to<br />
simulation correlation of high accuracy mechanism systems, with particular emphasis to frequency<br />
domain performances representation <strong>and</strong> advanced signal analysis techniques;<br />
3. mechanism simulation, using software packages like SIMPACK, ADAMS, DCAP <strong>and</strong> LMS Motion;<br />
4. feasibility assessments of new mechanisms design concepts;<br />
5. critical review <strong>and</strong> analysis of design solutions for mechanisms, <strong>and</strong> participation to project review<br />
processes;<br />
6. participation to CDF (Concurrent Design Facility) studies <strong>and</strong> involvement into the study sessions <strong>and</strong><br />
report preparation.<br />
<strong>Structure</strong>s <strong>Engineering</strong>:<br />
The Trainee will participate in the development <strong>and</strong> verification of spacecraft-<strong>and</strong> launcher structures. In<br />
assistance to <strong>ESA</strong> engineers working in this domain, the holder of the training position will be given a<br />
specific task which may include:<br />
1. Perform / evaluate instrument / satellite accommodation studies, familiarization with project<br />
requirements <strong>and</strong> CAD tools;<br />
2. Perform structural static / dynamic / vibro-acoustic / shock analyses for low, medium <strong>and</strong> high<br />
frequencies (Nastran, Abaqus, Samcef, VA-One, Dytran), in support to on-going spacecraft <strong>and</strong><br />
launcher programs;<br />
3. Participate to the definition / improvement / verification of structural & configuration analysis tools<br />
