Rich in history, values and know-how, we know at CMN NAVAL that the world is changing and our clients‘ challenges are evolving. We are committed to innovation and expanding our product range and solutions to meet our customer’s needs.
The search for speed through developing new hulls and lightweight structures, integrating increasingly complex combat systems, and reducing radar equivalent surfaces have long been at the heart of our research programs in the military field.
HydroQuest, a CMN subsidiary, is the leader in tidal Stream Energy and is currently the only company with functioning sea turbines. It has reached a significant milestone after a successful two-year test of its 1MW tidal turbine installation at the EDF site in Paimpol bréhat.
HydroQuest has designed the next generation of tidal turbines, which are even more efficient and powerful while being lighter, providing a competitive edge. These next-generation tidal turbines will be deployed at the FLOWATT project, a pilot farm of seven machines with 2.5MW unit power at the Raz Blanchard in Normandy
Tidal stream energy captures tidal currents’ forces and converts it into electricity. This inexhaustible, perfectly predictable, non-polluting energy source with no visual or noise pollution, has a potential estimated at around 100GW.
It’s been noted for some time that the combination of very high speeds and watercraft creates a high degree of uncertainty and difficulty in predicting performance and behaviour.
Bespoke CFD software has been developed specifically for high–speed applications in which aero simulations can run in tandem to hydro. The benefits of this are numerous, and CMN NAVAL is heading this innovation within the high–speed market.
When illuminated by an Electromagnetic Wave (EW), a metallic body scatters the EW in every direction, which is usually not desired. For example, backscattering (reflection) can cause antenna blockage, and forward scattering causes shadow zones.
As the incident field is null or very small in the shadow zones, targets in these regions will not be detected.
CMN NAVAL designs and builds a wide range of heavily armed surface combatants for a broad spectrum of operations from the littorals to open seas as stand-alone platforms or parts of the networked task force. For this reason, these surface combatants are equipped with multiple communications systems operating over a wide frequency band and at different powers.
Electromagnetic interference and electromagnetic compatibility are significant concerns in project development phases. Due to the number of antennas, these concerns are more critical in the V/UHF frequency band.
Modern military ships have antennas and radars dedicated to communication and combat systems. As a result, the arrangement and positioning of antennas and radars are complex from an Electromagnetic Waves (EW) propagation point of view.
