Definitions
- the invention relates to an inflatable sail and is in the field of sail propulsion or that of hybrid sail propulsion.
- - Reefing consists of reducing the surface of a sail by folding it in part from below, in order to adapt the surface of the sail to the force of the wind. Reefing can be done manually or automatically.
- - Lazy jacks device used to guide the sail to perform reefing and lowering maneuvers.
- a sail that fails is a sail that is insufficiently lined and partially deflates.
- a properly trimmed sail should be on the edge of flapping. With an inflated sail, there is no flapping, which allows you to stay facing the wind.
- Leading edge front part of a dynamic profile (wing, propeller, etc.) where a fluid will separate into two.
- Trailing edge characteristic part of any profile (wing, keel, rudder, etc.) subjected to a flow of a fluid (air, water, etc.) on both sides. It designates the part opposite to the direction of the direction, or in other words, the rear part considered in the direction of the flow.
- - Sail receptacle in addition to receiving the lowered sail, it can integrate other functions, such as taking up the tension forces provided by the sail, or housing other actuators, energy storage sensors and control module used to operate the sail.
- Aerodynamic drag component of the force experienced by a moving body in a fluid that is exerted in the opposite direction to the direction of movement. According to the invention, the sail generates aerodynamic drag.
- Aerodynamic lift component of the force experienced by a moving body in a fluid that is exerted perpendicular to the direction of movement. According to the invention, the sail generates aerodynamic lift
- Aerodynamic resultant vector sum of aerodynamic lift and aerodynamic drag.
- Angle of the sail angle between the plane of the profile of the sail and the axis of the boat.
- a sail propulsion element comprising an inflatable sail with a symmetrical profile.
- This propulsion element comprises an inflatable sail consisting essentially of two adjacent surfaces, substantially sealed and interconnected on their periphery, thus forming at least one closed cavity.
- the element further comprises a duct disposed between the interior and the exterior of the cavity and means for injecting air into the cavity.
- This sail once inflated presents a profile which remains permanently symmetrical, regardless of the displacement of the element, the direction or the intensity of the wind.
- the sail in this document is constantly inflated when used in navigation.
- a flexible sail has the drawback of not presenting an inflation adapted to the different stages of its use, and in particular during the lowering and hoisting phases.
- a flexible sail does not have a well-defined position during these handling steps (hoisting and lowering).
- the subject of the invention is a sail propulsion element comprising a mast, an inflatable or non-inflatable sail consisting essentially of two substantially sealed adjacent surfaces and connected to each other on their periphery, thereby forming between them at least one closed cavity.
- said sail comprising an upper part, a lower part, a leading edge and a trailing edge, the sail comprising different curves forming bulges over the entire length, an air duct arranged between the inside and the outside of the cavity of the sail, at least one means for injecting air into said cavity, the sail, once inflated, having a profile which remains permanently symmetrical, independently of the displacement of the said propulsion element, of the direction or of the wind intensity, a headpiece arranged on the upper part of the sail, a sail receptacle arranged between the leading edge and the trailing edge on the lower part of the sail.
- the propulsion element according to the invention is characterized in that the mast is arranged in front of the aerodynamic center of thrust of the sail, in that the mast is free or not to rotate through 360°, and in that the sail comprises at least one means making it possible to maintain a low pressure in the sail.
- the mast is driven in rotation by a system for adjusting the angle of incidence of the sail and it is able to rotate freely in the event of the mast being driven by a stop. said system.
- the mast is driven in rotation using an automatic management system which acts on the system for adjusting the angle of attack of the sail and, in the event of a breakdown or incident or voluntary stoppage of automatic management control, the mast is left free to rotate.
- the mast can thus perform several rotations on itself.
- incident or breakdown is meant, for example, the loss of the electrical power supply to the drive motor of the mast or that of the electronic components of the automatic management system, or even the reaching of a pre-established limit value of the torque of rotation of the mast. In these cases, the mast is left free to rotate, which allows the sail to be positioned facing the wind and to reduce the stress on the rigging and the boat.
- the sail propulsion element according to the invention has the following various advantages.
- the aerodynamic center of thrust is quite distinct from the mast, and is sufficiently far from it towards the rear of the boat.
- the position of the mast in front of the aerodynamic center of thrust of the sail allows the resultant of the aerodynamic forces on the sail to bring the sail, in all cases, facing the relative wind, except when the relative wind is zero.
- keeping the wing in a sufficiently inflated position thanks to the passive air inlets located, for example, on the leading edge allows it to maintain its profile, and thus prevent it from flapping even without active power supply. . In the situation where the relative wind is zero (thus preventing the sail from inflating), the sail will not flap.
- the aerodynamic center of thrust of the sail is remote from the mast by a length ranging from 0 to 10 m.
- the pressure maintaining means is an air intake opening arranged facing the relative wind. This air inlet helps maintain an internal pressure in the sail maintained by the relative wind.
- the transmission of energy and controls is carried out with a device which does not hinder said rotation.
- the device which does not impede the rotation is chosen from among the rotating joint or the cable carrying chain if it is accepted not to have an infinite freedom of rotation but limited to a few turns.
- the air intake opening comprises a movable closing valve.
- At least one guide line made up of one or more parts is arranged in the closed cavity of said sail, for the maneuvers of hoisting and lowering the sail, said guide line extending from the leading edge to the trailing edge of said sail, passing through the headboard and the sail receptacle.
- a guide line when a guide line is present, it consists of one part, and is fixed in a fixed manner to the sail receptacle on the trailing edge and movable by furler on the leading edge, or else , movable by furling at the sail receptacle on the trailing edge and fixed on the leading edge and the guide line is arranged along the headboard in a movable manner on at least one pulley between the trailing edge and the leading edge 'offensive.
- a guide line when a guide line is present, it consists of two parts, the first part on the trailing edge side is fixed or else movable with a pulley on the headrest and movable by winder on the receptacle, the second part on the leading edge side, is fixed or mobile with a pulley on the headrest and mobile by retractor on the receptacle.
- Another object of the present invention is a sail or hybrid propulsion vehicle comprising at least one sail propulsion element as mentioned above, a hull and a mast secured to said hull, but still free to rotate.
- This vehicle is characterized in that the mast is arranged inside the cavity of the inflatable sail mentioned above.
- vehicle we mean any machine including wheels or not, moving on land, on water, ice, snow, mud.
- the sail is oriented according to the direction of the wind, and the direction of travel of the vehicle manually or automatically, making it possible to optimize the thrust in the axis of the boat or to achieve the desired thrust, while by limiting forces, pressures and list to acceptable values.
- the mast When the mast is not free to rotate infinitely, it can simply, for example, perform two turns on itself, in one direction, without blocking with a cable carrying chain. In such a case, he will then have to turn in the opposite direction to put him back in a correct navigation position.
- hybrid propulsion vehicle By hybrid propulsion vehicle according to the invention is meant sail propulsion coupled to another source of propulsion such as for example propulsion by a propeller, driven by an electric or combustion engine, with as energy storage from batteries, hydrogen (with a fuel cell), natural gas or fuel oil.
- FIG. 1 shows a reminder of the different physical forces that apply to a ship, for example of the sailboat type with an engine, and in particular the projection of the resulting aerodynamic force;
- FIG. 2 shows a schematic sectional view of the sail propulsion element according to the invention, arranged on a boat hull;
- FIG. 3A, 3B and 3C each represent a schematic top view of the position of the propulsion element according to the invention, according to different relative wind angles.
- a sail-powered vehicle hereinafter referred to as a sailboat or ship, is in contact with the air and with the water.
- the preponderant factors are the hydrodynamic and aerodynamic forces acting on the hull, the sails and the appendages (daggerboards, keel, rudder), propeller.
- the aerodynamic force results from the deflection of the air by at least one sail. Aerodynamic force is relative to the sail and the position and strength of the relative wind. The drag force is in the direction of the relative wind, the lift force is in the perpendicular direction of the relative wind, it is not always perpendicular to the sail. For example, at 0°, a symmetrical profile has no lift due to the fact that the air travels strictly the same distance on the upper surface and the lower surface. It only generates drag at this time.
- the aerodynamic force generated by the sail can also be broken down in the reference frame of the boat, and not in that of the sail, to be composed of the propulsive force of the sail (which is in the axis of the boat's movement) and in a force of drift (perpendicular to the axis of the boat) which can induce list (transverse inclination of a boat caused by an external phenomenon such as the wind).
- the hydrodynamic force results from the friction of the water on the hull and the centerboard or keel and the various submerged appendages. Its direction depends on the aerodynamic force it opposes, the propulsive force in hybrid mode, the state of the sea and the ocean currents.
- the longitudinal component is called hydrodynamic drag
- the transverse component is called drift lift or anti-drift force or hydrodynamic lift.
- the direction and the intensity of the hydrodynamic force does not depend only on the aerodynamic force. For a building (boat) operating in hybrid mode (wind and other energy), the hydrodynamic force will strongly depend on the speed of the building generated by the thermal or electric propulsion for example, the state of the sea and the marine currents.
- the boat (sailboat) will achieve its maximum performance in terms of sailing thrust in the direction of travel. Indeed, it is the optimization of the angle of the sail in relation to the relative wind, the direction of the boat and the adjustment of the surface of the sail which will allow the boat to reach the maximum of its sail propulsion in the axis of the boat. There may be additional adjustment by adjusting the internal pressure of the sail. This makes it possible to increase the speed of the boat or, on the contrary, to maintain the same speed while reducing the consumption of other energies, thanks to the sail propulsion.
- Figure 1 takes each of the previous denominations with its own reference listed below: a: lift force b: drag force c: aerodynamic resultant force d: Aerodynamic thrust force (in the axis of the ship) e: Aerodynamic drift force f: Relative wind g: Relative wing angle - boat axis (ex: 15°) h: Relative wind angle and boat axis (ex: 30° ) i: Propeller propulsive force j: Hull k: Sail I: Mast m: Aerodynamic center of pressure n: Propeller o: sensor on fixed part (hull frame of reference) p: sensor on mobile part (sail frame of reference)
- FIG. 1 makes it possible to pass from the data sensors originating from the reference frame of the hull, to the data sensors originating from the reference frame of the sail, and vice versa.
- FIG. 2 shows the sail propulsion element according to the invention, mounted on a boat, sailboat type, in the operating position.
- This element comprises a general reference sail 1 mounted on the hull 2 of a boat.
- the element comprises a mast 3 whose base 4 is fixed to the hull 2, while allowing the rotational movement of the mast 3.
- the mast 3 is self-supporting.
- the connection of the mast 3 with the shell 2 is carried out using a support (not shown) intended to recover the efforts of physical force and leave the degree of freedom in rotation.
- the forces are measured at the level of the support(s).
- Sail 1 comprises two adjacent surfaces 5 (only one is shown in the figure) interconnected so as to form a closed cavity.
- the material used for the two adjacent surfaces 5 must limit permeation so as to reduce air consumption, and thus allow the recovery and transmission of the various forces present. In some cases, it may be necessary to add different treatments to the material so as to guarantee by example a certain resistance to fire, to UV, or to apply an antistatic treatment.
- the sail 1 comprises several curves (not shown) regularly distributed over the height (the curves are larger in the lower part of the sail, and smaller in the upper part).
- the height of the curve is often linked to the length of the chord of the profile.
- the curves give it the external appearance of a bellows.
- the sail 1 comprises an upper part 6, a lower part 7, a leading edge 8 and a trailing edge 9.
- At least one air inlet 18 is arranged, for example, at the level of the lower part 7 of the veil 1 .
- Other air inlets 30 can also be arranged on the surface of the leading edge 8.
- At least one active means for injecting air 7a within the cavity of the sail is arranged in the extension of the duct d air so as to be able to inject air into the cavity of the sail.
- the sail further comprises a headrest 10 disposed on its upper part 6, and a sail receptacle 11 disposed on its lower part 7 between the leading edge 8 and the trailing edge 9. This receptacle 11 is intended to receive all or part of the sail when lowered.
- This receptacle 11 is intended to receive all or part of the sail when lowered.
- the 11 can include various actuators and sensors to facilitate manual or automatic maneuvering when raising or lowering the sail 1 .
- the sailing propulsion element according to the invention comprises a guide rod
- This guidance line is intended for guiding the sail during hoisting and lowering and reefing maneuvers of the sail 1 .
- This line 12 extends substantially over the perimeter of the sail 1.
- the guide line 12 is removably or not, but not movable, fixed at one end
- the guide line 12 is movable along the headboard 10 at the using at least two pulleys or other possible return systems (not shown) each arranged on either side of the mast 3. This guide line 12 is adjacent to the leading edge 8, towards the sail receptacle 11, to then be fixed using a furler 19 on the sail receptacle 11 substantially at the level of the leading edge 8.
- the guide line 12 can be mounted towards a blocking cleat if it is operated manually. On the other hand, it is wound on an automatic winder for the automated version.
- the guide line 12 has a length of approximately 50 meters for a sail having a total area of approximately 100m 2 , and a tension of between approximately 50 and 250N depending on the uses made of it during the various maneuvers of lowering or hoisting.
- the mast 3 can be telescopic or fixed. When the mast 3 is telescopic, the headrest 10 is secured to the last element of the telescopic mast 3, which can retain a degree of freedom in rotation, either with respect to the mast, or with the last element of the mast which rotates. When the mast 3 is telescopic, it consists of different elements which slide successively relative to each other to deploy or retract. If there is no reefing (case of transport ships) it is possible to deploy one element after the other constituting the telescopic mast, or all the elements at the same time.
- the sail 1 being fixed to the headrest 10, descends or rises with the latter.
- the headrest can be in free rotation, locked in rotation or locked in rotation up to a certain force value. It is also possible to have a servo control of the angular position of the headrest in order to control the twisting of the sail. Indeed, the wind speed is not the same at all altitudes, it may be interesting to adapt the angle of attack of the sail at different altitudes to adapt to different variations in relative wind.
- the headrest 10 comprises sufficient rigidity in order to communicate the physical forces existing between the various ropes and the mast 3, but also to support the weight of the sail when it is not inflated.
- the headrest 10 can be, as desired, in free rotation around the mast 3, locked in rotation around the mast 3, locked in rotation around the mast 3 up to a limit value of couple to limit the efforts to an acceptable value (the maximum acceptable value will depend on the construction of the system and the parts that one wishes to protect with this safety system) or even slaved so as to control the twisting of the sail.
- the mast 3 is connected, fixed to the hull 2 using a mast support 14 whose role is to take up the different physical forces existing between the sail and the boat while leaving the mast a degree of freedom in rotation so as to be able to position oneself at the right angle in relation to the relative wind.
- This system 15 may consist, inter alia, of a motor.
- This system 15 allows the sail 1 to be able to perform rotations around the axis of rotation of the mast 3, and consequently to control the desired angle of incidence of the sail 1 .
- This system for adjusting the angle of incidence can also be mounted integrally with respect to the mast 3, for example on the "nest" (or sail receptacle) with a motor driving via a pinion a crown integral with the hull .
- the sail propulsion element according to the invention arranged on the hull of a boat can also be combined with a torque limiter, arranged at the base of the mast 3, and known to limit the maximum torque transmissible by the sail 1 to hull 2.
- the propulsion element according to the invention disposed on the hull of a boat may further comprise an electronic control system 16 disposed in the receptacle 11 of sail.
- An electric rotary joint 17 can be added in the hull at the lower base of the mast 3. This joint 17 makes it possible to transmit the electric power and the electric commands between the hull 2 and the lower part 7 of the sail 1, without limitation of the number rotation turns around the mast 3 achievable with the sail.
- the seal 17 can also be replaced by a suitable conventional cable carrier chain.
- the energy used to actuate the element according to the invention is, for example hydraulic or pneumatic, a hydraulic or pneumatic rotary joint can be used.
- the sensors for measuring the force transmitted from the sail 1 to the hull 2 the sensors for measuring the force in the transverse axis of the hull 2, the sensors for measuring the force in the longitudinal axis of the hull 2, the pressure sensor in the internal cavity of the sail 1, and the sensor for measuring the speed and the angle of the relative wind.
- This last measurement can just as well be carried out on the sail 1 as on the hull 2.
- the sensors are placed on the integral part of the mast 3, they measure the forces in the longitudinal axis and the transverse axis of the veil 1 .
- the sail 1 can further comprise a sail neutralizer (not shown) which would be stored in the sail receptacle 11 or in the headrest 10.
- a neutralizer would allow, when deployed from the bottom to the top of the sail, or from top to bottom of the sail, to encapsulate the sail, thus reducing its volume by removing the interior air, and therefore preventing it from blowing, and reducing its wind resistance.
- Figures 3A, B and C are distinguished from each other by a different angle of incidence of the sail.
- the relative wind is in the axis of the sail.
- the axis of the sail presents an angle substantially equal to 15° with respect to the direction of the relative wind
- the axis of the sail presents an angle symmetrical and equal to that represented in Figure 3B with respect to relative wind direction.
- the sail 1 has a substantially symmetrical profile.
- Mast 3 is symbolized by a circle.
- the relative wind is symbolized by arrow 23.
- Figure 3A shows a sail 1 in a stabilized state, facing the wind 23.
- the different forces are balanced.
- the aerodynamic lift is zero (since it is identical on both sides of the sail due to its symmetrical profile), only the drag 24 exists and maintains the sail along an axis parallel to the axis of the relative wind.
- Figure 3B shows a sail 1 whose axis has an angle of approximately 15° with respect to the direction of the relative wind.
- the axis of rotation of the mast 3 is offset forward of the profile with respect to the center of thrust 25 of the aerodynamic forces along the axis of symmetry of the profile.
- FIG. 3B shows that the torque generated by the aerodynamic force at a certain distance from the center of rotation of the mast 3 has tendency to bring the sail back to its position facing the relative wind, where it can remain stable thanks to the symmetrical profile of the sail.
- the existing offset between the point of rotation of the mast 3 and the center of thrust 25 allows the propulsion element of the invention to guarantee maintenance of the sail 1 as much in situations of large angle difference with the direction of the wind than those of small deviation.
- Such an offset between this point of rotation of the mast 3 and the center 25 makes it possible to carry out the abseils of the sail 1 towards the neutral position of the sail, that is to say facing the wind when it deviates from it. .
- Such an offset makes it possible to reinforce the safety of navigation since the sail returns by itself to a suitable and optimal position in relation to the direction of the relative wind, which minimizes the efforts and keeps the sail in a position facing the wind. This distance must however be minimized so as not to excessively increase the forces necessary for the rotation of the sail.
- Figure 3C is the figure symmetrical to that of Figure 3B with respect to the axis of the relative wind. The same remarks as those of Figure 3B apply.
- the outer layer of the sail also called bodywork, consists of a fabric comprising an outer part in contact with the outside air, and an inner part.
- This fabric can be made of a woven polyester coated with polyurethane.
- the weight of this fabric can be 110 g/m 2 for a canopy of around 100 m 2 .
- the attachment of the upper part of the sail can be carried out using hook-and-loop strips, of the VELCRO type.
- the connections between the outer parts of the sail and the ribs (internal connections) as well as the connections between the components of the outer part, can be made by welding or gluing or any other means of connection (zipper for example) making it possible to guarantee both a sufficiently low level of permeation compatible with the existing inflation system and also guarantee the passage of forces.
