HAPPY 2 follows on from the HAPPY project and aims to optimise the control settings developed to compensate for the flexibility of parts and tools in continuous servo processes and to test them in more complex scenarios of aeronautical
use, but also in defence situations for the navy.


The previous HAPPY project (07/2018 – 11/2022) validated for two situations of aeronautical usage the development of a control setting able to compensate for the flexibility of parts and tooling based on continuous local measurements. This makes it possible to envisage aeronautical assembly lines capable of:
• flexibility in terms of output and product variants,
• working without intensive use of overhead cranes, since such operations currently create bottlenecks in aeronautical assembly workshops,
• working without use of tools anchored to the floor.

On the Naval Group side, the developments concerning continuous servo assembly offer an excellent opportunity to standardise
production methods and to validate the referencing of two large submarine parts horizontally, and to eliminate turning operations
after initial positioning.
