Definitions

  • the present invention relates to a gearbox arrangement for use with hydrofoil systems employed on yachts, sailboats, ships, and other waterborne vessels.
  • the present invention relates to such a gearbox with heat transfer cooling system.
  • a sailing hydrofoil is a wing-like structure mounted under the hull of a boat, such as a yacht, that provides a speed advantage over more traditional boat designs.
  • the sailing hydrofoil works with its wing-like appendage.
  • a hydrofoil in the water accomplishes the same thing.
  • the main difference is that a hydrofoil does not need to be as large as an airplane wing, because the water is much denser than air.
  • the hydrofoils lifts most of the hull, or even the entire hull, up and out of the water, greatly reducing the wetted area, resulting in decreased drag and increased speed as the craft cuts through the water.
  • a sailing hydrofoil could be a single hull, often referred to as a mono hull, a catamaran (which has two hulls), or a trimaran (which has three hulls). In the case of multiple hulls, the hulls are held together by a single upper deck. The wider and longer the ship, the more stable the sailing hydrofoil is.
  • Conventional hydrofoils are used in either a passive way i.e. there is no active control on their geometry, or in an active way i.e. using flaps to cause the craft to ascend or descend and to control the craft about its pitch, heave, and roll axes.
  • all control is manual e.g. using a control system with a mechanical lever arm, and the flaps require human intervention, which inherently requires extensive experience by a user and exposes the craft control to human error.
  • there is an inherent trade-off between a requirement for faster and more accurate control and overall drag (a lower drag foil will come at the cost of inherent stability).
  • Hydrofoil water vessels may be wind powered (e.g. yachts, sailing boats), or powered using an engine and gearbox mounted on the hull and mechanically engaged with a propeller system mounted adjacent the foil on the underside of the hull.
  • wind powered e.g. yachts, sailing boats
  • engine and gearbox mounted on the hull and mechanically engaged with a propeller system mounted adjacent the foil on the underside of the hull.
  • propeller system mounted adjacent the foil on the underside of the hull.
  • a first aspect of the present invention provides a gearbox system for a waterborne vessel with a hydrofoil, the gearbox system comprising:
  • At least a portion of the housing is integral with the hydrofoil.
  • the whole of the housing is integral with the hydrofoil.
  • the profile of the gearbox system is significantly reduced.
  • This layout significantly reduces the wetted area of the drive train, therefore reducing hydrodynamic drag of the eFoil system, improving efficiency and autonomy.
  • the gearbox system is mounted on the hydrofoil. This allows the gearbox system to be completely separated from the Foil, allowing for Drive train fast replacement in case of maintenance, therefore minimizing downtime for commercial vessels.
  • the gearing system and engine are a close fit within the interior space of the housing.
  • the close fit allows the engine and gearbox to be in thermal contact with the gearbox casing such that heat generated by the engine and/or gearbox during use may be transferred by contact to the gearbox casing, which is subsequently cooled by the surrounding water in which it is submerged. No mechanical or forced water flow is required to cool the engine and gearbox.
  • the engine is located adjacent the gearbox.
  • the gearbox casing forms part of the foil and locates the engine to the foil structure.
  • the gearbox casing is thermally conductive in order to cool the engine and gearbox by heat transfer into the surrounding environmental water.
  • the gearbox casing comprises metal, and preferably coated or non-corrosive/corrosive resistant raw metal.
  • any suitable known to the skilled person and highly resistant to corrosion could be used as an alternative to, or in addition to, using metal for the gearbox casing.
  • the gearbox housing further comprises a power train engagement portion.
  • the power train engagement portion engages with a power train connected to the controller on the hull of the vessel. This provides electrical communication between the controller and the engine and gearbox.
  • the power train engagement portion is located distal to the propeller shaft engagement portion. This prevents any fouling of the power train by the moving parts of the propeller.
  • the gearing system is an epicyclic gearbox (also known as planetary gearbox).
  • epicyclic gearbox also known as planetary gearbox.
  • any other suitable reduction system known to the skilled person and suitable for function could be used in addition to, or as an alternative to, an epicyclic gearbox.
  • the engine comprises a high-power density electrical engine, referred to as a Motor Generator Unit (MGU).
  • MGU Motor Generator Unit
  • the engine may comprise an MGU and the gearbox may include epicyclic reduction hardware, both being located within the watertight gearbox casing.
  • the gearbox casing may comprise, but is not limited to, any one or more of the following materials, including stainless steel (all grades), titanium alloy, aluminium (aluminum). However, it is to be appreciated that any other suitable material known to the skilled person may be used to make up the gearbox casing. Preferably, an appropriate sea water coating is applied to the gearbox casing to render the gearbox more resistant to sea water erosion. It is to be appreciate that any other material known to the skilled person and suitable for function may be used in addition to, or as an alternative to, the aforementioned materials. Such other materials may include, but are not limited to, one or more of a composite material such as Aramid fibre, or carbon fibre reinforced resin material.
  • a second aspect of the present invention provides a hydrofoil system for a waterborne vessel, the hydrofoil system comprising a controller; a foil for engagement with the waterborne vessel, the foil comprising a plurality of adjustment members operable to vary the lift characteristics of the waterborne vessel; a propeller mounted on the foil; and a gearbox system according to a first aspect of the present invention, wherein the propeller is mechanically engaged with the propeller shaft engagement portion and the gearbox system is in mechanical communication with the propeller.
  • the hydrofoil system further comprises a plurality of sensors in electrical communication with the controller, each sensor configured to monitor flight parameters of the waterborne vessel and generate measured flight parameter data, wherein the controller is in communication with the adjustment members, the engine and the sensors and wherein the controller is configured to receive measured flight parameter data from the sensors and to control the operation of the engine and the position of the adjustment members in dependence upon the received measured flight parameter data.
  • each of the adjustment members is operable to vary one or more of pitch, roll, heave, and yaw of the waterborne vessel.
  • each adjustment member comprises a flap and an actuator, wherein the flap is moveable relative to the foil on activation of the actuator by the controller.
  • the adjustment member further comprises a hydrodynamic fairing within which the flap is arranged.
  • the actuators are integrated within the foil.
  • the actuators may alternatively be integrated inside the vessel, depending on the respective sizes of the foil and vessel.
  • each of the plurality of flaps is independently adjustable. This provides greater control over the position of the vessel within the water.
  • the plurality of flaps comprises at least one set of two aligned flaps. However, additional flaps may be provided within each set of flaps if required.
  • the propeller is located adjacent to the gearbox, and distal to the engine.
  • the propeller is located adjacent to the gearbox, and distal to the engine, via a short propeller shaft, in order to minimise efficiency loss.
  • each foil of the present invention is composed of two lifting surfaces: the elevator (horizontal part) which provides vertical lift; and a shaft, whose main purpose is to carry the elevator and also provide side force in turns and manoeuvres.
  • the measured flight parameter data may comprise any one or more selected from the group comprising acceleration data, vessel position data (pitch, heave, yaw, roll), actuator positional data, external environmental factors (e.g. wind, wave-height) and any other useful data relating to the movement of the vessel through the water, and the environment the vessel is moving in.
  • the controller is located within the hull of the waterborne vessel and the foil is located beneath the floating waterline on the hull exterior of the waterborne vessel.
  • the hydrofoil system further comprises a battery system in electrical communication with the engine and optionally the actuator, wherein the battery system is operable to provide power to the engine and optionally the actuator.
  • the adjustment member may be actuated using hydraulic power.
  • a battery system may comprise a Power Electronics Control Unit (PECU).
  • a third aspect of the present invention provides a waterborne vessel including a hydrofoil system according to a second aspect of the present invention. It is to be appreciated that the hydrofoil system according to the second aspect of the present invention may be provided integrally as part of a new vessel during manufacture, or may be provided for retrofit to an existing vessel. In both cases, the vessels will then have all the advantages provided by the hydrofoil system. Such advantages include:
  • the hydrofoil system of the present invention provides a high efficiency and low consumption propulsion system for high speed marine travel whilst providing autonomous control of a fully submerged actively controlled foiling waterborne vessel.
  • FIG. 1 shows a waterborne vessel in the form of a monohulled vessel 10 provided with an embodiment of a hydrofoil system in accordance with a first embodiment of the present invention.
  • the hydrofoil system comprises a controller 12 located within the hull 14 of vessel 10.
  • a battery system 16 is located adjacent controller 10, and in electrical communication with controller 10.
  • battery system 16 comprises a Power Electronics Control Unit (PECU).
  • PECU Power Electronics Control Unit
  • a foil 18 is located on the outer surface of the foil hull below the floating waterline.
  • Foil 18 comprises a plurality of adjustment members 19 operable to vary the lift characteristics of the vessel 10 during travel.
  • Each adjustment member comprises a flap 20 and associated actuator 22.
  • Actuators 22 can be either electric or hydraulic and may be integrated within foil 18 (as shown in figure 1 ) or may be located within the vessel 10 itself depending on the vessel size and associated foil size. Actuators 22 operate to control the position of associated flaps 20 to control the ship in heave i.e. ride height 24 relative to the floating water line 26), pitch, roll and thrust.
  • Ride height 24 is shown in figure 1 and is based on the distance between the water surface (floating water line 26) and the foiling water line 28.
  • Foiling water line refers to where the water free surface sits, relative to the foils/hull, while airborne. When the boat is floating, the water line is defined by how much the hull needs to sink to obtain the volume of displacement (under Archimedean hydrostatic force). When foiling, the foiling water line is the optimum between minimum foil immersion (the vertical part "shaft") to reduce drag without having the elevator 52 ventilating because of the free surface proximity.
  • the adjustment member 13 further comprises a hydrodynamic fairing 21 within which the flap 20 is arranged.
  • each foil comprises four flaps 20, each flap 20 is independently operable by an associated actuator 22.

  • Engine 42 is an MGU.
  • engine 42 is electrically coupled to battery system 16 and controller 10 via electrical harness 50 that extends through vertical shaft 30, such that, in use, electrical harness 50 transfers energy from the battery system 16 to engine 42 which drives propeller drive shaft 46 via gearbox 44 to rotate propeller 32.
  • the engine 42 acts as a generator, deploying energy from the battery system 16 to drive gearbox 44.
  • Electrical harness 50 is a flexible electrical connection, rather than a conventional mechanical linkage.
  • the presence of a flexible electrical harness 50 extending vertically through foil 18, rather than a mechanical linkage, allows for more streamlined containment of the connection within the foil, thus permitting an improved foil profile with increased hydrodynamic efficiency.
  • Fluid inlets 42 are provided radially around body 34 such that channel 36 is in fluid communication with the exterior of foil 18 i.e. exterior water may flow through fluid inlets 42 into channel 44.
  • water flows through fluid inlets 42 into channel 36 and flows past engine 42 and gearbox 44 in a direction towards the second end 40 of channel 36. Further, water will be drawn in through open first end 38 of channel 36 and also flow past engine 42 and gearbox 44 towards second end 40.
  • the flow of exterior water into channel 36 and around engine 42 and gearbox 44 serves to cool the engine and gearbox during use, preventing overheating and allowing operation of the engine and gearbox at higher speeds than possible in the absence of a cooling system.
  • fluid inlets 48 are shown as slots or gills
  • any suitable shape of fluid inlet known to the skilled person and suitable for the circulation of water from the exterior of foil 18 into channel 36 and around engine 42 and gearbox 44 may be used in addition to, or as an alternative to, the slots or gills shown in figures 6 and 7 .
  • the number and location of fluid inlets 42 may be varied from that shown in the figures provided a sufficient volume of fluid flow past engine 42 and gearbox 44 is possible to provide the required cooling to be achieved during travel of vessel 10.
  • foil 18 comprises a housing 60 defining a receiving space in which engine 42 and gearbox 44 are received.
  • Housing 60 provides a watertight housing for engine 44.
  • Engine 42 and gearbox 44 are located adjacent one another within housing 60housing 60 and are connected via shaft 66 that transmits the torque and rotation from engine 42 to the gearbox 44.

  • the vessel 10 is further provided with a plurality of sensors (not shown) in electrical communication with controller 12, each sensor configured to monitor one or more flight parameters of vessel 10 and generate measured flight parameter data based on the monitored flight parameter.
  • This measured flight parameter data is then provided to controller 10 which uses the measured flight parameter data to determine what adjustments are required to the engine and adjustment members 13 to optimise the vessel 10 travel through the water.
  • Adjustment member 13 is shown in figures 2 and 3 with its hydrodynamic fairing.
  • Controller 10 then communicates engine 42 to control the operation of propeller 32.
  • Controller 12 also communicates with actuators 22 to control the position of the adjustment members 13 in dependence upon the measured flight parameter data. This has the effect of influencing the speed of the vessel through the water and/or the position of vessel 10 within the water i.e. the heave, pitch, roll and/or thrust of vessel 10 within the water.
