Sonaca covers for Ariane 6

Located in Cluj, Sonaca Romania employs 210 people in the aerospace sector. The company plays a key role in supplying parts for major aircraft manufacturers and contributes to the Ariane 6 programme. For this rocket, Sonaca Romania produces two main types of components.

The first are composite covers that serve as protective caps for sensors on the rocket. Around thirty carbon-fibre parts are manufactured at their Romanian facility.

The second type is the BACO L-Square and Upper Cover assemblies. These assemblies include aluminium components that are stretched and machined in Belgium at Sonaca’s headquarters before being assembled in Romania. These structural rings are positioned in the lower section of the boosters and are essential to maintaining the rocket’s integrity during launch.

Together, these components enhance the Ariane 6's aerodynamics and structural performance, showcasing Sonaca’s expertise in advanced aerospace solutions.
