MERLIN Instrument Support Structure. Customer: Airbus Defence & Space


MERLIN will measure methane concentrations in the atmosphere to help understanding of global warming.
In order to minimise the thermo-elastic effects on this very sensitive instrument, a support structure with CFRP sandwich design and low CTE metallic interfaces is designed.

Space Structures provides the following structures engineering services:

More details
  • Detailed local FEM modelling of CFRP Sandwich panel details and CFRP honeycomb core
  • Static Analysis
  • Verification of strength of all interface elements (metallic, CFRP, adhesive)

MetOp-SG 3MI Instrument Baseplate. Customer: INVENT / LEONARDO


The MetOp-SG 3MI Instrument (Multi-viewing, Multi-channel, Multi-polarisation Imager) is designed primarily for aerosol observation. It will also greatly support the observation of Earth radiation budget, clouds microphysics, soil condition, ocean color.
The baseplate of the instrument is a complex CFRP sandwich design to minimise thermo-elastic effects on the instrument.

Space Structures provides the following structures engineering services:

More details
  • Detailed FEM modelling of CFRP Sandwich panel with many dedicated CFRP local design solutions
  • Incorporation of condensed Craig-Bampton Models of Instrument
  • Modal Analysis
  • Thermo-Elastic Analysis
  • Optimization of Baseplate performance
