Definitions
- the present invention relates to a wing-type sail system and, more particularly, to a rigid wing mid-mounted on a mast assembly configured for controlling the pitch, roll and yaw and optionally height of the wing with respect to a vessel.
- Wing-type sails are known for use on both land and sea-type wind-powered vehicles.
- wing-type sails are typically rigid or semi-rigid symmetrical airfoils that develop lift from the passage of wind thereupon; a wing-type sail is typically mounted vertically and is pivotable about its vertical axis.
- Generating useful propulsive force in any given direction requires the ability to controllably align the angle of attack of the wing relative to the direction of the wind.
- the profile of the wing has to be symmetric (around the profile centerline) - a less than optimal profile for maximizing lift forces.
- AU7484281 relates to a sail, mast, and control arrangement. This sail system is to eliminate or minimize the heeling force while still being able to tack and allow adjustment of the sail for different points of sailing.
- GB2307457 shows a similar arrangement.
- GB1184914 relates to a pivoted rigging for sailing boats or sail propelled vehicles.
- This system comprises an airfoil carried by a rotatable mast extending upwardly from the main body of the boat or vehicle, the airfoil being rotatable with the mast about a substantially vertical axis with respect to the main body of the boat or vehicle.
- the present invention successfully addresses the shortcomings of the presently known configurations by providing a wing-type sail system which enables a user to control the roll and yaw of a substantially rigid asymmetric profile wing having a very high lift coefficient (C Lmax higher than 3.0, up to about 4.5 or more) with respect to the vessel, thus enabling a user to optimize the angle of the wing with respect to the wind.
- C Lmax higher than 3.0, up to about 4.5 or more
- the present invention is of a wing-type sail system which can be used as a propulsion or a propulsion-assist device on land or water vehicles.
- Rigid wing-type sails similar in structure and function to an aircraft wing are known in the prior art. Such sails provide sail-like functionality via a rigid, lift optimized structure which produces a forward 'lift' when mounted upright on a vessel, i.e. it produces a force in the forward direction on the vessel thereby propelling the vessel forward.
- FIG. 1 at B centerline shown by dashed line
- Figures 2a-e illustrates tacking under changing wind/movement directions in a vessel with a symmetric wing-type sail mounted on an upright mast (W - wind direction, D - vessel sailing direction).
- symmetric wing sails ( Figure 1 at B ) can generate at least as much lift as an ordinary sail ( Figure 1 at A ) they generate less lift than an asymmetric airfoil wing sail ( Figure 1 at D and E ).
- sail manufacturers have added a trailing edge winglet (See Figure 1 at C ) which increases the maximum lift coefficient of the symmetric wing. Such a configuration is substantially more efficient in harnessing the wind than an ordinary sail and has been utilized by boats racing the America's Cup.
- Aeroskimmer (www.dcss.org/speedweek/aeroskimmer.html). Although the Aeroskimmer solves most of the aforementioned problems, control over the wing and in particular, adjusting wing alignment to changing wind directions is difficult to achieve due to its mast system and its connection to the wing.
- An asymmetric wing (asymmetric around the profile center line) generates more lift than a symmetric wing since it maximizes the difference in the speed of air flowing over the top side (convex/cambered) and the bottom side (flat or concave). This in turn maximizes the static pressure difference between the top and bottom surfaces of the wing and the lift force pointing from the concave side to the cambered side (per Bernoulli's law).
- a wing-type sail refers to a substantially rigid sail that has wing functionality, i.e. it can generate lift from air flowing over its surface.
- substantially rigid refers to a wing structure that has a rigid cover, i.e. a cover that maintains its shape and is not dependent on wind for shaping.
- the wing-type sail of the present invention can include a wing-like frame (spars and profiles) covered with a stretched fabric, a polymer or a composite (fiberglass, carbon fiber).
- the wing-type sail of the present invention can be a solid structure composed of a lightweight foam core that is covered with a composite.
- the present system includes a mast assembly pivotally mounted on a swiveling base attachable to a water craft/vessel (e.g. yacht, racing boat, ship and the like) or a land craft/vehicle (e.g. land yacht).
- the swiveling base can be attached to the deck or to a structure mounted on the deck or hull.
- the present system further includes a substantially rigid and asymmetric wing pivotally attached to a top of the mast assembly, preferably at the mid wing point (e.g. center of gravity) such that it balances on top of the mast assembly.
- Table 1 below lists the maximum lift coefficients of various wing profiles.
- An asymmetric airfoil has a maximum lift coefficient that can be 30-40% higher than that of an ordinary sail ( Figure 1 at A ) and a symmetric profile wing ( Figure 1 at B ).
- An asymmetric airfoil with a leading slat and trailing winglet can generate a maximum lift coefficient of 4.5, three times the lift per m 2 of surface of an ordinary sail.
- the wing sail of the present invention is mounted on a mast assembly that both rotates and flips the wing sail when tacked (i.e. controls both roll and yaw of the wing).
- the mast assembly includes one or more mast poles (e.g. 1, 2, 4, 8 mast poles) that are attached to a swiveling base (turret) which is attached to the vessel.
- the top of the mast poles are attached to a mid portion (around or at the center of gravity) of the wing sail via a hinge assembly which can include an axle/shaft/rod/pin fitted within friction/roller bearings.
- the hinge assembly enables the wing sail to roll around the hinge axis from an upright position (vertical or nearly vertical) on one side of the mast assembly to an upright position on an opposite side of the mast assembly (see description related to Figures 4a-e below for further detail).
- the swiveling base can rotate the wing assembly such that the leading edge of the wing sail is correctly angled with respect to the wind to provide lift.
- the mast assembly can alternatively include telescoping mast poles that can be selectively actuated to roll the wing sail by lifting one side and lowering the other.
- the present system also includes a control mechanism for modifying a height, pitch, roll and yaw of the wing with respect to the craft as well as a wing span thereof.
- the control mechanism can include winch motors, hydraulic pumps, mechanical or electric transmission, or the like for angling the mast assembly and for raising or lowering each of the mast poles.
- the control mechanism preferably includes winch motors and pulleys which are attached via rigging (e.g. steel, Kevlar wires) to the top of the mast assembly and to the wing tips.
- Figures 3-4e illustrate one configuration of the wing-type sail system of the present invention which is referred to herein as system 10.
- the skeleton (spars and profiles) of wing 20 is fabricated from an alloy, a polymer, carbon fiber or wood and is covered with rigid or semi-rigid panels (alloy, polymer, carbon fiber or cloth).
- Wing 20 can be constructed from several foldable or telescopic segments (which can be retracted/expanded via control mechanism) similar to wing 120 shown in Figure 5 .
- Figures 4a-e illustrate repositioning (tacking) of system 10 in order to change sailing direction (D) under a steady wind (wind direction - D).
- Figures 4a-e illustrate a change of 70 0 in route direction in 14 0 increments.
- the vessel is turned 70 0 clockwise causing the wind direction to rotate 70 0 anti clockwise from front right to front left.
- wing 20 is rolled clockwise from -80 0 to +80 0 while base 18 is rotated 34 0 counterclockwise [from +35 0 - 18 0 (angle of attack) to -35 0 + 18 0 (angle of attack)] relative to the vessel's longitudinal centerline.
- Such roll and yaw of wing 20 as affected through hinge 22 and mast assembly 12 is used to reposition wing 20 to maximize lift under any change in wind direction or vessel route.
- Mast poles 104 are preferably telescopic and include 2 or more segments (three shown) that can telescopically extend or retract to adjust a height, pitch yaw or roll of an attached wing 120.
- Mast poles 104 can include a spring mechanism (coil spring or an air piston) which is compressible when mast poles 104 are pulled down and retracted. When a pulling force is partially or fully released, the compressed spring mechanism extends mast poles 104.
- Wing 120 can be constructed from several foldable or telescopic segments 124 (which can be retracted / expanded via control mechanism). In the embodiment shown in Figure 5 , wing 120 includes 7 interconnected segments 124; with segments 126 and 128 being telescopically retractable into segment 130 (using mechanical or hydraulic mechanisms).
- Wing 120 can be fabricated with a variety of dimensions depending on the craft and purpose and can be a single foil (as is shown in the Figures) or a multi-foil configuration.
- System 100 also includes a control mechanism 132 which includes motors 134 with attached pulleys 136 (shown in detail in Figure 6 ). Braided steel or aramid cables (guy wires) 138 (four shown) are spooled over pulleys 136. Thus, motors 134 and attached pulleys 136 function as winches for pulling or releasing cables 138. Each pulley 136 functions independently to spool a cable 138 attached thereto. As is shown in Figures 5-6 , a pair 140 of cables 138 is preferably connected to each pulley 136 (cables 138 can be a single cable looped over pulley 136). Each cable 136 of the pair is connected to a different portion of wing 120.

- Mast pole 2 length Meter On top of mast pole 2 9.
- Mast pole 3 length Meter On top of mast pole 3 10.
- Mast pole 4 length Meter On top of mast pole 4 11.
- Systems 10 and 100 further include a control unit (not shown), preferably positioned in the cockpit on the bridge.
- the control unit includes a user interface for controlling control mechanism 32 or 132 and for obtaining information related to a state of wing 20 or 120 (e.g. from above describe sensors), mast poles 14 or 114, swiveling base 18 or 118 and any other component of system 10 or 100.
- the control unit is wired to control mechanism 32 or 132 or is wirelessly connected thereto via an RF communication module.
- the control unit can operate in an open loop mode, in which case relevant information (from the sensors) is displayed to an operator which then modifies wing 20 or 120 position accordingly, or it can operate in a closed loop mode (auto-pilot) in which case, the computer of the control unit will make decision based on sensor data and course plotted.
- the closed loop mode the operator can override computer control at any point in time.
- Figure 8 illustrates closed loop control over wing 20 or 120 and base 18 or 118 based on sensor data.
- system 10 assemblies can be used on a craft.
- a large water craft such as a tanker ( Figures 7a-b ) can utilize several system 10 or 100 assemblies (9 shown), each having a dedicated control mechanism 32 or 132.
- one or more control mechanism 32 or 132 can be used to control several mast/wing assemblies.
- control mechanism(s) 32 or 132 are preferably each controlled via a single control unit which can also retrieve and display to an operator sensor reading from each mast/wing assembly.
- a wing having 600 m 2 can provide, in case of CLmax 4.5 and apparent wind velocity of 10 m/s (19.4 Knot) from a beam and air temperature 10 0 , a propulsive force of 169,000 Newton (N).
- CLmax 4.5 apparent wind velocity of 10 m/s (19.4 Knot) from a beam and air temperature 10 0
- a propulsive force of 169,000 Newton (N) can be provided.
- ten such system 10 or 100 assemblies can provide a propulsive force of 1,690,000 N which can lead to considerable savings in fuel.
- the perfect angle of the wings relative to the wind is automatically and continuously controlled by a control unit of the present invention (receiving input from sensors - wind direction and speed, vessel's sailing direction) and produce output to activate electro mechanical units that maneuver the wings.
- Any voyage is planned in advance according to weather conditions along the planned route at the planned dates, and the amount of fuel needed (or saved) is calculated automatically computationally.
