The European Space Agency (ESA) is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.
Find out more about space activities in our 23 Member States, and understand how ESA works together with their national agencies, institutions and organisations.

Go to topicFree and constrained viscoelastic treatments are well established damping techniques, but more efficient solutions can very often be obtained by combining mechanical amplification and constrained layer damping. The figure illustrates such concepts with two SPADD or ‘Smart Passive Damping Device’ damping solutions developed by ARTEC Aerospace: SPADD-pad for an engine (left) and linear SPADD devices for aircraft shield (right).
