  • the improved fluid foil system 10 of the present invention is depicted as part of a sailboat construction including a hull 12 of any suitable construction.
  • the foil system 10 includes a foil 14 including a pair of flexible A-frame spars 16 which serve to stretch a delta-form sail 18 therebetween.
  • the foil 14 may be otherwise con ⁇ structed including formation from rigid sheet materal and the like.
  • a cross bar 24 extending between the spars 16 serves to stretch the sail 18 and maintain it in such condition.
  • the foil 14 is torsionally mounted to a mast 26 generally along its longitudinal axis of lateral symetry such that the foil 14 may assume various positions of lateral tilt with respect to the mast as shown by the arrows in Figs. 4 and 5. Such connection is accomplished by means of a sleeve 28
  • a connector 32 of any suitable construction serves to fasten the pin 30 on the other side of the mast 26 such that the cross bar 24 and, accordingly, the foil 14 is free to assume the lateral tilt in either direction as above-described. It will be apparent in this construction that the lateral aerodynamic lift forces are largely counterbalanced about the flexible mast mount which in this case is a pivotal connection.
  • the foil 14 when otherwise unconstrained, is free " to seek a luffing attitude of pitch where the angle of attack of the foil 14 in regard to the wind forces (assumed to be generally parallel to the surface of the water on which the sailboat is supported) essentially neutralizes the lift forces of such fluid medium against the foil.
  • a strut 34 is attached to a collar 36 so as to enable pivotal motion in a vertical plane of such strut.
  • the collar 36 is in turn adjustably fixedly connected to the mast 26 at one end and extends up ⁇ wardly to the nose 20 of the foil 14 at its other end. Accordingly, this strut 34 extending between the leading nose 20 of the foil 14 serves to position the pitch of the foil's longitudinal axis. Normally such pitch is set such that the foil assumes a horizontal, i.e., position parallel to the water, such that foil has a neutral lift when disposed in its normal luffing or level attitude as shown in Fig. 1.
  • the mast 26 is supported by being appropriately “stepped" in the hull 12 and is free for ulti- rotational movement with regard thereto.
  • OMPI mast 26 has a rotational degree of freedom greater than 360° with respect to the hull 12 in either direction. It thus may be seen that the combination of the ability of the mast to rotate in the above- indicated manner with the ability of the foil 14 to tilt about the mast in either lateral direction enables the foil 14 to assume a wide range of directional headings and positions vis-a-vis the directional flow of the wind such that the desired degree of its force may be harnessed in any particular case. ' Also, the torsional link between the foil 14 and mast 26 eliminates any complication or entangle ⁇ ment of these means of attitude positioning and control since they rotate in unison to any directional heading, including multi-rotational weathervaning.
  • the above-described support or connection of the foil 14 to the mast 26 need not however be a direct connection.
  • the foil could be connected to a sleeve or some other member in turn supported by the mast and capable of free or at least multi- rotational movement with respect to the mast.
  • the mast itself would not need to be capable of actual rotation with respect to the boat or other support.
  • the term mast as used herein and including the claims of this application is used in a broad sense which would include such an intermediate member such as a sleeve, etc. , in other words , the mast supports the foil for multi-rotational movement.
  • a continuous sheet 40 is attached to the spar 15 some distance behind the cross bar 24.
  • the sheet 40 control forces are minimized.
  • the aerodynamic lift forces applied to the foil 14 are also generally laterally balanced about its longitudinal axis of lateral symetry because its pivotal mount is centrally located on this axis.
  • the foil may, however, be purposely unbalanced to enable aerodynamic leveling as for instance shown in Figs. 15 - 17.
  • a minimum force is required to mechanically induce a leveling or horizontal- seeking lateral attitude towards which the foil tends to return when otherwise unconstrained, i.e., by the force application to the control sheet 40 in either direction.
  • Force application is accomplished simply by the operator grasping and pulling the appropriate side of the sheet and released by the operator flipping the sheet aftward to clear the sheet from the fairleads 41.
  • a self-leveling assembly 42 is provided such that the foil when otherwise unconstrained will seek a rest, level, or luffing attitude generally normal
  • level, leveling, etc. means in a preselected attitude with respect to the mast which is generally but not necessarily normal thereto.
  • leveling system 42 includes a V-shaped yoke 44 attached to opposite sides of the cross bar 24 by means of sleeves 46.
  • the apex 46 of such yoke 42 is attached to a cord 48 extending into the hollow interior of the mast 26 through an opening.50 proximal the yoke apex 46 when the foil 14 is in the normal rest attitude.
  • the cord 48 is connected in turn to a spring 52 mounted in the interior of the mast 26 and, accordingly, the cord 48 serves to place a continual downward and inward force upon the yoke 42.
  • the cord 48 could be an elastic cord commonly referred to as a "shock cord".
  • the term spxing encompasses members which apply a spring-like force, e.g., spring reels, cylinders, etc. It may be thus apparent that when the foil 14 assumes a lateral tilt with respect to the mast such as shown in Fig. 5 that the downward force applied thereto by the self-leveling means 42 tends to return the foil to its level or rest position shown in Fig. 4.
  • the term "cord” as used above and hereinafter includes flexible tensile members, e.g., flexible joined links, e.g., chain, wire cable, and the like.
  • the self-leveling means may also be integral
  • a leveling spring therein (see Fig. 20) , connected with the foil as described with regard to the system 42 above or separate but in operational contact as with the self-leveling means 60 illustrated in Figs. 8 and 9.
  • the cross bar 24 of the foil is pivotally connected to the mast 26 by a pin 62 extending to opposite sides of a bifuracted upper mast terminus.
  • a sleeve 64 is adapted for slidable movement on the mast from a point proximate a fixed collar 66 to a point proximate the pivotal connection with the cross bar 24.
  • a compressed coil spring 68 is disposed between the collar and the sleeve so as to continually urge the sleeve upwardly where a pair of arms 70 upwardly outwardly extending from the sleeve 64 are adapted to respectively contact opposite sides of the cross bar 24 dependent- on the tilt attitude thereof so as to continually urge such to a level position.
  • the sleeve 64 is similarly forced to move downwardly against the action of the spring 68.
  • self-leveling means 42 as well as self-leveling means, 60 have been illustrated as disposed below the position at which the foil is supported by the mast, there is no reason to limit such disposition since the self-leveling means could be positioned above the foil in those cases where the mast projects a suitable distance above the foil connection. In such cases, the self-leveling means
  • the present foil system provides an inherent mechanism by which the wind force acting upon the foil can be immediately and automatically be shut off regardless of wind orientation as by disengaging the sheet 40 from the fairlead being used and upon which it will assume its rest or luffing position. Such is important especially in mooring or making landings in cramped quarters or in difficult wind circumstances.
  • the present foil can shut off its sail power in any directional heading and in widely veering winds simply by releasing the sheet so that the foil automatically levels to its weathervane or rest position.
  • Such system includes a sleeve 78 slidably supported on the mast 26 but fixed in position with respect thereto in a manner which will be hereinafter indicated.
  • the sleeve includes a vertically extending open slot 80 on one side thereof.
  • These bolts 82 are oriented with respect to the slot 80 such that the sleeve 78 may slide up and down on the mast but will not rotate with respect thereto inasmuch as the contact between the heads of the bolts 82 and the opposed edges of the sleeve 78 which form the slot 80 prevents such action.

Abstract

Un systeme ameliore a feuille fluide est particulierement adapte, sans toutefois etre limite, a une utilisation dans des bateaux a voiles. Lorsqu'elle est utilise dans un voilier la feuille (14) est supportee en rotation par rapport a un mat (26) et peut etre inclinee lateralement autour d'un axe longitudinal soit dans un sens soit dans l'autre pour recevoir le vent qui propulse le bateau (12) sur lequel le mat (26) est monte. Le mat (26) peut etre monte dans le bateau (12) a son autre extremite de maniere a permettre une rotation libre par rapport au bateau. De plus, le systeme est pourvu de moyens d'auto-nivellement (42, 60) de la feuille (14) pour la pousser de maniere continue vers sa position de repos ou non inclinee, c'est-a-dire dans une position generalement parallele a l'eau, par consequent avec un angle d'attaque nul par rapport au vent. Cette combinaison d'une feuille a auto-nivellement inclinable et en rotation libre permet de fixer la feuille (14) au mat (26) avec un poids structural minimum. Ceci a son tour permet une commande a la fois simplifiee et amelioree de la feuille (14) et du bateau (12) qu'elle propulse ainsi qu'une utilisation maximum de vents legers et forts d'une maniere qui n'avait pas ete possible jusqu'a present.
