Chapter 1: Traction Avant, https://lnkd.in/eSZ_kiw3,
EU Patent: https://lnkd.in/eHaYdVMP, Fig.13 and Fig.14.
The video shows the flow around the engine nacelle of a new pod propulsion system. In this system, the patented torque stage — consisting of two annular blades — is located upstream of the engine nacelle, facing the direction of travel of the watercraft. The nacelle is designed to spread the flow of water in a cone-shaped manner. This ensures that both the smaller and larger blades are approached by the flow at a positive angle of attack. This remains true even at speeds exceeding eight knots, at which point the inflow becomes more parallel to the chord lines of the two annular blades. In this configuration, the two annular wings experience the lowest possible flow resistance in the water. The cross-section of the smaller annular blade has a distorted profile that only changes to a hydrodynamically effective profile at the intended rotational speed due to the oblique flow passing over it. Red streamlines depict the flow's angle of attack. Additionally, the front-mounted propulsion system operates the generator of the electric engine housed in the effective flow-dynamic nacelle design. In this case, the nacelle acts as a flow guide, ensuring the flow approaches the two ring blades at a positive angle of attack. The pod propulsion system is mounted on the hull of a watercraft and can rotate through 360°. This allows it to function as a rudder propeller. This innovative propulsion system is suitable for small watercraft with 20–200 kW engines, as well as larger vessels with 100 MW engines. The larger fixed ring blade can have a diameter of up to 10 meters.

Chapter 2: Double Kort Nozzle with Electric Drive: https://lnkd.in/eciu7S6p
EU Patent: https://lnkd.in/eHaYdVMP, Fig.13 and Fig.14.
The smaller annular vane is connected to the rotor of an annular electric motor along with four propeller blades. The rotor and stator of the electric motor are integrated into the larger annular vane. Watertight mechanical seals allow the electric drive to be integrated into the larger annular vane. The suction sides of the smaller upstream ring wing and the larger downstream ring wing rotate towards the axis of rotation. Red flow lines show how the shrouded jet engine draws in water and accelerates it in the direction of travel within a concentric flow funnel. The jet engine can be aligned transversely to the direction of travel. At speeds of up to eight knots, the flow funnel ensures that the smaller, rotating ring wing and the larger, stationary outer ring wing are approached by the flow at a positive angle of attack. This generates thrust in the direction of travel. The lift generated by the two asymmetrically profiled annular wings acts in the direction of travel. With its thrust vector, the lift contributes significantly to increasing the efficiency of the ramjet engine. Unlike a symmetrical airfoil profile, which forms the casing of the Kort nozzle, an asymmetrical airfoil profile generates approximately one-third more lift. When the incoming flow has a positive angle of attack relative to the airfoil chord, the thrust generated by the two annular wings increases by a third. The electric drive system, which is designed for a torque stage formed by two ring blades, is presented here for the first time. It is particularly well-suited to watercraft designed for a cruising speed of eight to ten knots. Watercraft fitted with an electric outboard motor with a power output of up to seven and a half kilowatts can be operated without a license.
For the electric propulsion system integrated into a ring wing, the upper power limit is approximately 1,400 kW, which would correspond to a maximum diameter of 2 m for the turbo propulsion system.

Chapter 3: Featering Two Ring Vanes, https://lnkd.in/ecEBXkMk
EU - Patent: https://lnkd.in/eHaYdVMP, Fig. 17
The European patent specification illustrates a new ship propulsion system. The impeller's three blades are connected to a rotating ring vane whose suction side is oriented toward the axis of rotation. When the assumed rotational speed is 600 RPM, a cross-section taken parallel to the axis of rotation reveals a distorted wing profile with a hydrodynamically effective form. In this operational state, the asymmetric wing profile's contour effectively guides the inflow to a larger ring vane that is firmly connected to the motor's nacelle in the pod propulsion system. The ring wings, arranged one behind the other in the direction of travel, form a torque stage that generates thrust. Red flow lines show the flow striking both ring vanes at a positive angle of attack, creating lift on both ring wings. This creates a thrust force that can be directed within a 180-degree angle in any direction. The jacketed impeller also prevents abrasion caused by cavitation at the blade tips. Additionally, the jacketed impeller is characterized by smooth, silent operation, which benefits the underwater fauna. Pod drives of this type can have propeller diameters ranging from two to ten meters and can be built to deliver power outputs between 150 and 150,000 kilowatts.

Chapter 4: One Rigid and One Rotating Ring Foil: https://lnkd.in/eXVhGgMT
EU- Patent: https://lnkd.in/eHaYdVMP, Fig.1 to Fig.5.
A jacketed rudder impeller is used in pod propulsion systems. At the stern of a watercraft, the engine nacelle connects to the hull via a pivot. This allows the thrust generated by the two ring wings to be directed in the desired travel direction. In this example, the smaller ring wing, positioned upstream, is rigidly connected to the engine nacelle. It acts as a flow guide for the inflow to the larger ring wing, which is positioned downstream. Once the watercraft is in motion, both ring wings generate thrust in the direction of travel. The propeller accelerates the flow locally and directs it in a funnel-shaped pattern toward the axis of rotation. Once the watercraft has gained speed, as demonstrated in the video, only the larger ring wing provides thrust in the direction of travel because the flow around the smaller wing is essentially parallel. Two concentric electric motor shafts are arranged within the motor nacelle to make two motor discs rotate in opposite directions. This causes the flow around the ring wings to be essentially parallel to the axis of rotation.

Chapter 5: Featuring a Set of Four Ring Foils: https://lnkd.in/eVSHg7J4
EU- Patent: https://lnkd.in/eHaYdVMP, Fig.1 to Fig.5.
The second embodiment of the pod propulsion system can also be used as a rudder Impeller. It is rotatably connected to the underwater hull and comprises a first and a second thrust stage. Each stage is formed by two annular blades arranged consecutively in the direction of flow. As in the first embodiment, the smaller of the two annular blades is rigidly connected to the motor nacelle, which is designed in accordance with fluid dynamic principles. To achieve the most powerful possible underwater propulsion, the ring blades of a thrust stage can be designed to rotate in opposite directions.

Chapter 6: Coordinated Swarm Propulsion, https://lnkd.in/eSSW7PAx
EU - Patent: https://lnkd.in/eHaYdVMP, Fig.1 to Fig.5,
US Patent : https://lnkd.in/eG3rxDAw, Fig.26, Fig.27,
EU Patent : https://lnkd.in/e4AJ8DX6
This patented system features a multitude of pod units which use swarm intelligence to manoeuvre the vessel. Tugboats are no longer needed when entering the port. The ship can manoeuvre independently. Catamaran-like underwater uplift bodies are used to store H2 fuel for fuel cells, which power the electric pods. There is much more in the pipeline. The teardrop-shaped pod itself acts as a flow guide for the two counter-rotating propellers, generating thrust in the direction of travel. Firstly, radial rotor blades generate thrust according to the recoil principle and are connected to outer ring vanes. On the other hand, the flow streaming the smaller and larger ring vanes at the rear end of the pod has a positive angle of attack. This causes a lift force at both ring vanes, resulting in thrust in the direction of travel. The smaller ring vane, positioned upstream, acts as a guide for the larger, downstream ring vane.

Chapter 8: Submarine Propulsion: https://lnkd.in/eDzDdjvh
EU- Patent: https://lnkd.in/eHaYdVMP, Fig.6 and Fig.7.
Team RES is proud to present a new propulsion system for submarines. A torque stage with three annular blades is located at the submarine's stern. In this example, the smaller of the two annular blades is designed as a sequence of two annular blades, shown in white, which are rotating counterclockwise connected to stator of an electric drive integrated in the submarin's hull. The suction side of both annular wing profiles faces the hull, utilizing the laminar flow around the hull to generate silent thrust upstream of the downstream-located impeller. The cockwise rotating largest annular wing forms the impeller casing and contributes to the submarine’s quiet propulsion. The torque stage can also be integrated into a surrounding flow channel that is rigidly connected to the hull to prevent sound transmission to the water. Team RES is happy to answer any questions about this extraordinary propulsion system.

Chapter 10: Outboard Motor, https://lnkd.in/erxkNdNG,
EU Patent: https://lnkd.in/eHaYdVMP, Fig. 13 and Fig.14
The video shows a controllable-pitch propeller designed as an outboard motor with an electric drive. The smaller annular blade leads the direction of flow and is connected to the larger annular blade via pivot axes. The larger annular blade forms the motor housing for the annular stator of the electric motor and is connected to three propeller blades. When switching from forward to reverse propulsion, the rotor blades automatically adjust with a 10-degree swivel range each. The outboard motor can be manually operated within a power range of 5 to 200 kW. In this embodiment, the suction sides of the asymmetrical airfoil profile of the ring wings are oriented toward the axis of rotation. The faster the propeller rotates, the more the flow is drawn into a funnel towards the axis of rotation. The flow accelerates in the Venturi nozzle formed by the smaller ring blade, which can be described as a flow guide ring for the larger ring blade.

Chapter 11: Jet Propulsion System, https://lnkd.in/ec9FhSnB,
EU Patent: https://lnkd.in/eHaYdVMP, Fig. 19.
The video shows a water jet propulsion system for a watercraft. The first stage of the torque mechanism is a three-bladed propeller, as described in the invention. The propeller is driven by a shaft and connected to an annular ring vane at its outer end. The curvature of the vane is oriented towards the axis of rotation. At the intended speed, the first annular wing is angled so that the flow passes obliquely over it. This forms a flow-guiding ring for the second, larger-diameter annular wing located downstream. The suction side of the second annular blade is on the outside of an overflow chamber within the jet propulsion system. This chamber is shaped according to fluid dynamics principles. A tapered inlet chamber is integrated into the stern of the hull and positioned upstream of the enclosed engine chamber. An outlet nozzle at the stern of the vessel accelerates the water jet expelled by the vessel. The water jet is expelled by the vessel. As the red flow lines show, the larger annular wing sweeps over at a positive angle of attack. This generates a lift vector directed in the same direction as the vessel's travel. The horizontal component of this lift vector forms the thrust vector.
