ADV Propulse
Founded in 2020, ADV Propulse is a subsidiary of ADV Tech, which has been working since 2012 on the development of a new type of high-efficiency biomimetic rotor.
Since 2017, work has focused on naval propulsion, the sector in which the technology’s differentiating factors and marketing prospects are strongest.
The markets addressed by ADV Propulse are as follows:
- USV drones: thrusters from 1 to 5 kW;
- yachts: thrusters from 15 to 50 kW;
- professional boats (intervention launches, fishing, coastal work): 100 to 800 kW;
- passenger transport (promenade, ferries): 500 kW to 3 MW;
- offshore services (wind farms, O&G): 600kW to 3 MW.
ADV Propulse is structured around a design office with a simulation platform and a design team, and a prototyping and thruster assembly workshop.
The trochoidal propulsion system developed by ADV Propulse is an innovative biomimetic naval propulsion technology that offers an alternative to conventional propellers. It operates on the principle of blades rotating around a vertical axis, enabling the generation and direction of thrust over a full 360° without a traditional rudder.
Its main advantages include exceptional maneuverability (rotation in place, lateral movement, dynamic positioning), improved energy efficiency of up to 25% depending on the configuration, and a low underwater acoustic signature. Its kinematics and rotational speed help minimize cavitation and underwater noise. Its mechanical architecture, which does not require individual electronic actuation of the blades, ensures the system’s simplicity and facilitates its integration onto various platforms. Adaptable to a range of power levels and energy sources, the ADV Propulse propulsion system meets the needs of both the civilian and defense markets, from small craft to commercial vessels and autonomous surface vehicles (USVs). It also enables operation at high speeds.
The ALERION is a 2.10-meter electric autonomous surface vehicle (USV) developed by ADV Propulse for demanding maritime missions. Equipped with two 5-kW electric trochoidal propellers, it offers exceptional maneuverability thanks to 360° steerable thrust, a low acoustic signature, and excellent efficiency, which increases its range. Compact, lightweight, and rapidly deployable, it can reach speeds of up to 20 knots, carry a payload of up to 50 kg, and operate in shallow waters with a minimum draft of 20 cm. Equipped with a triple-redundant autopilot, an open architecture, and autonomous mission programming capabilities, the ALERION enables precise operations tailored to various maritime environments. Its versatility meets the needs of civil security, hydrography, and bathymetry, as well as defense and maritime surveillance applications.

ADV Propulse’s trochoidal propulsion technology is particularly well-suited for unmanned surface vehicles (USVs), thanks to its 360° maneuverability, excellent efficiency, low acoustic signature, and precise movement. ADV Propulse offers, in particular, the ALERION, a 2.10-meter autonomous electric USV equipped with two 5-kW propellers, and can also supply its propellers to other drone manufacturers wishing to integrate this technology into their platforms.
ADV Propulse is a company developing a breakthrough technology in marine propulsion: a vertical-axis propeller known as a trochoidal propeller, which replaces the conventional propeller.
Drone de surface (USV) Alerion 2.10m
L’ALERION est un drone de surface autonome (USV) électrique de 2,10 m, développé par ADV Propulse pour les missions maritimes exigeantes. Équipé de deux propulseurs trochoïdaux électriques de 5 kW, il offre une manœuvrabilité exceptionnelle grâce à une poussée orientable à 360°, une faible signature acoustique et un excellent rendement, augmentant son autonomie. Compact, léger et rapidement déployable, il peut atteindre 20 nœuds de vitesse, embarquer jusqu’à 50 kg de charge utile et évoluer dans des eaux peu profondes, avec un tirant d’eau minimal de 20 cm. Doté d’un pilote automatique à triple redondance, d’une architecture ouverte et de capacités de programmation de missions autonomes, l’ALERION permet des interventions précises et adaptées à différents environnements maritimes. Sa polyvalence répond aux besoins de la sécurité civile, de l’hydrographie et de la bathymétrie, ainsi qu’aux applications de défense et de surveillance maritime.
Propulseur trochoïdal
Le propulseur trochoïdal développé par ADV Propulse est une technologie innovante de propulsion navale biomimétique, alternative aux hélices conventionnelles. Son principe repose sur le mouvement de pales autour d’un axe vertical, permettant de générer et d’orienter la poussée à 360° sans gouvernail traditionnel.
Ses principaux avantages sont une manœuvrabilité exceptionnelle (rotation sur place, déplacement latéral, positionnement dynamique), une amélioration du rendement énergétique pouvant atteindre 25 % selon la configuration, une faible signature acoustique sous-marine. Sa cinématique et sa vitesse de rotation contribuent à limiter la cavitation et le bruit sous-marin. Son architecture mécanique, sans actionnement électronique individuel des pales, favorise la simplicité du système et son intégration sur différentes plateformes. Adaptable à plusieurs puissances et sources d’énergie, le propulseur ADV Propulse répond aux besoins des marchés civils et de défense, des petites embarcations aux navires professionnels et aux drones de surface autonomes (USV). Il permet également d’évoluer à des vitesses importantes.
ADV Propulse has a workshop dedicated to the development, assembly, and testing of its propulsion systems. The company uses prototyping equipment—including 3D printers—to design, manufacture, and improve its technological solutions.
ADV relies on R&D programs and collaborations with leading organizations. The TROCHOPROP project, conducted with CEPN, demonstrated a 14% reduction in fuel consumption (with the potential to reach up to 30%). The company has also contributed to the European SATURN program on acoustic signature in collaboration with Naval Group and SIREHNA.
Innovative propulsion system
ADV Propulse develops innovative vertical-axis propellers, known as trochoidal propellers, that improve ships’ propulsive efficiency and reduce their energy consumption by up to 25 percent. Their design combines propulsion and steering functions, providing omnidirectional maneuverability and eliminating the need for certain appendages, such as the rudder. The energy savings thus result from the propeller’s kinematics and the reduction in drag caused by these appendages.
ADV Propulse designs and develops innovative propulsion systems that combine energy efficiency, omnidirectional maneuverability, mechanical simplicity, and a low acoustic signature. Its solutions are designed for both civilian and military markets, ranging from small boats to commercial vessels and surface drones (USVs).
