Stockholm. Naval Group participated at UDT 2019 in Stockholm, Sweden from May 13-15 to present its underwater systems.
Presenting underwater systems
During UDT 2019, Naval Group showcased many of its innovative underwater vessels and solutions, developed through its close relationship with the French Navy.
SMX® 31: “the electric”
SMX® 31 is a showcase of developments Naval Group is studying for the next generation submarine. This resolutely digital submarine, designed to operate in a highly demanding environment, will carry out information gathering missions and will be more than ever capable of forceful actions that will result, either by using adapted weapons, or by “special” action modes (disruptive action modes adapted to different situations).
SMX® 31 is fitted with significantly increased energy power which allows remaining submerged, stealth and manoeuvring during extended periods. The whole combat system and platform management system are fully integrated. She benefits from the latest developments in terms of Artificial Intelligence (AI). With a perfect hydrodynamic shape (inspired by biomimicry), specially designed for stealth versus active acoustic means, SMX® 31 is totally undetectable.
D19 multi-mission torpedo drone
Drawing on its experience in autonomous underwater vehicles, Naval Group has developed a new Unmanned Underwater Vehicle (UUV) called the D19. The family of D19 drones is equipped with modular front-end payload, meaning it can easily be adapted for each mission. It can be launched by a submarine, a surface vessel or from the shore.
Equipped with modular payload at the front end, which can be easily switched thanks to a plug-and-play system, D19 can fulfil a wide variety of missions, such as identification, surveillance, recognition; electronic warfare; anti-submarine warfare; underwater mobile target; mine countermeasures or rapid environmental assessment.
The D19 is built on a F21 torpedo base. This way, Naval Group takes advantage of its experience accumulated with the development of this torpedo. The D19 is propelled by a Lithium-ion energy section. Already sea proven thanks to the joint effort of Naval Group and the French Navy, the D19 combines long endurance and intelligence.
Smart energy: AIP revolution and a new generation of Lithium-ion batteries system for submarines
Naval Group has developed an Air Independent Propulsion (AIP) system powered by second generation fuel cells called FC2G. Naval Group AIP gives non-nuclear submarines unprecedented operational ability by enabling them to stay submerged for weeks at a time.
Naval Group has also developed a high performance and highly secure Li-on batteries system to provide its submarines with outstanding operational capabilities, as well as with an immersion period and reloading time largely optimized. The Li-ion batteries system LIB, improves security and performances on-board submarines developed by Naval Group
Facing underwater future challenges
During UDT 2019, Naval Group experts took part to conferences on:
Improving the submarine sonar array integration for operational performance (May 13, Edouard Honore – Naval Group & Christophe Lozach – Thales, Theatre 1)
Simulating the Radar Cross Section (RCS) of the wake of a submarine at periscope depth (May 15, Eric Letouzé, Theatre 2)
Confusion and dilution countermeasures (May 13, Sebastien Colson, Theater 4)
System engineering for complex system design (May 13, Romain Le Néna, Theater 2)
Thinking tomorrow’s submarine to face operational challenges in constraint environment, the example of the SXM31 (May 15, Armel De Roeck & Lou Durand, Theater 4).
Another round of conferences will be dedicated to torpedoes:
CFD simulation of a torpedo swim-out launching (May 13, Fabian Pécot & Thierry Taillefet, Theater 4)
Heavyweight torpedoes program: management of validation and qualification processes (May 13, Eric Lescoat, Theater 4)
Finally, Naval Group will present its innovations in the range of prediction tools and acoustic performance:
Performance of prediction tools for submarine manoeuvrability in constrained and shallow water (May 14, François Pétillon, Theater 2)
Numerical prediction of non-cavitation noise from the propeller (May 15, Frédérique Chevalier, Theater 2)
Analysis of the vibro-acoustic behaviour of a submarine hull on a wide frequency range using experimental and numerical approaches (May 15, Valentin Meyer, Theater 2).
