q'amure s'effectuant par action différentielle sur ces câbles. q tack is effected by differential action on these cables.
La version ci-dessus fonctionne convenablement lorsque l'inclinaison des câbles sur l'eau, qui détermine l'angle de roulis, reste entre certaines limites A défaut, les organes d'appui enfoncent trop dans l'eau en détériorant la trainée, ou au contraire émergent trop et contrôlent mal le tangage La présente invention rend le planeur aquatique peu sensible a l'inclinaison de roulis et en simplifie la construction. Selon la présente invention, on constitue comme pour le brevet précédent un planeur aquatique par -. une aile incurvée à symétnrie avant-arrinére, en forme de crochet semi-immergé dans l'eau avec un prolongement hors d'eau (direction " au vent "), une poutre, fixée perpendiculairement sur l'aile, portant en extrémités des organes d'appui sur l'eau. Les différences sont les suivantes - La poutre est placée non plus sur l'extrémité du prolongement mais au milieu du crochet, sur la jpnction entre l'aile et le prolongement The above version works properly when the inclination of the cables on the water, which determines the roll angle, remains between certain limits. Otherwise, the support members sink too much into the water, deteriorating the drag, or on the contrary emerge too much and poorly control the pitch The present invention makes the aquatic glider not very sensitive to the inclination of roll and simplifies the construction thereof. According to the present invention, as for the previous patent, an aquatic glider is constituted by -. a curved wing with forward-rear symmetry, in the shape of a hook semi-immersed in water with an extension out of water (direction "to the wind"), a beam, fixed perpendicularly on the wing, bearing at the ends of the organs support on the water. The differences are as follows - The beam is no longer placed on the end of the extension but in the middle of the hook, on the jpnction between the wing and the extension
- les deux câbles d'attache sont fixés avec un certain écartement sur l'extrémité du prolongement. - the two attachment cables are fixed with a certain spacing on the end of the extension.
- Les ailerons d'appui sont fixes, placés perpendiculairement aux extrémités de la poutre vers le côté q sous le vent " (opposé aux câbles), avec une courbure dont la concavité est vers le haut Leurs extrémités, ainsi placées sensiblement dans le plan vertical de la partie active de l'aile, ont des plans tangents sensiblement parallèles a la poutre et passant au dessous de la poutre et par l'extrémité du prolongement d'aile - The support fins are fixed, placed perpendicularly to the ends of the beam towards the leeward side q (opposite to the cables), with a curvature whose concavity is upwards Their ends, thus placed substantially in the vertical plane of the active part of the wing, have tangent planes substantially parallel to the beam and passing below the beam and through the end of the wing extension
L'invention sera décrite à l'aide de la Figure 5, vue perspective de la nouvelle disposition. The invention will be described using Figure 5, perspective view of the new arrangement.
L'aile comporte une partie semi-immergee 1 incurvée selon l'envergure en arc de cercle de rayon R et d'environ 150 , dans le sens d'un crochet visà-vis de la portance obtenue, la corde de profil atteignant par exemple 0, 4 R. Le profil symétnrique est constitue par exemple d'un arc de cercle en extrados et d'une corde droite en intrados avec une épaisseur relative de 0,15 L'aile se prolonge vers le côté " au vent " par une partie émergée 2 droite trapézoïdale d'une longueur de l'ordre de 2 R et dont le profil peut être le même, se terminant par une barre perpendiculaire 3 d'une longueur de l'ordre de R aux extrémités de laquelle s'attachent les câbles 4 et 4' allant au bateau a voile ou à l'aéronef (planeur, parapente, ballon) Sur le milieu de l'aile, entre les parties 1 et 2, est fixée la poutre perpendiculaire 5, tube d'une longueur de l'ordre de 10 R, se terminant par des embouts 6 et 6' courbés vers le haut Près de ces I5 extrémités sont fixés, vers le côté " sous le vent ", des ailerons 7 et 7', par exemple en tôle plate, incurvés avec la concavité vers le haut pour faciliter un dérapage sur l'eau vers le vent, avec une The wing comprises a semi-immersed part 1 curved according to the span in an arc of a circle of radius R and about 150, in the direction of a hook with respect to the lift obtained, the profile rope reaching for example 0, 4 R. The symmetrical profile is constituted for example by an arc of a circle on the upper surface and a straight cord on the lower surface with a relative thickness of 0.15 The wing is extended towards the "windward" side by a emerged part 2 trapezoidal right with a length of the order of 2 R and the profile of which may be the same, ending in a perpendicular bar 3 with a length of the order of R at the ends of which the cables 4 and 4 'going to the sailing boat or the aircraft (glider, paraglider, balloon) On the middle of the wing, between parts 1 and 2, is fixed the perpendicular beam 5, tube with a length of in the order of 10 R, ending with end pieces 6 and 6 'curved upwards Near these I5 ends are fixed, towards the side "under the wind", fins 7 and 7 ', for example in flat sheet metal, curved with the concavity upwards to facilitate a skidding on the water towards the wind, with a
longueur de l'ordre de 0,7 R et un rayon de courbure de l'ordre de R, les extrémités se trouvant sensiblement à 0,3 R au dessous du plan du prolongement 2, selon des plans tangents voisins passant près de l'extrémité du prolongement 2. length of the order of 0.7 R and a radius of curvature of the order of R, the ends being substantially 0.3 R below the plane of the extension 2, according to neighboring tangent planes passing near the end of extension 2.
Le fonctionnement est le suivant Les deux câbles se trouvent tendus en oblique vers le bateau ou l'aéronef et l'aile se déplace dans l'eau, presque perpendiculairement aux câbles du fait de sa portance hydrodynamique et dans le sens correspondant au câble le plus tendu L'aile est stabilisée en semi- immersion, roulis et cap par la tension des câbles, et en tangage par la poutre 5 et ses ailerons. La répartition des pressions sur l'aile immergée, avec une résistance de sillage en partie haute, cause un' couple cabreur qui élève au dessus de l'eau l'aileron avant et applique sur l'eau l'aileron arrière en hydroplanage. L'aile prend également en plan une incidence positive qui place les extrémités incurvées des ailerons en une position de dérapage favorisant l'hydroplanage L'aile rencontrant une vague et l'aileron avant touchant l'eau, cette incidence positive en plan, accrue par lI choc, fait dégager l'aileron vers le haut sans enfournement On évite l'enfournement de la poutre 5 The operation is as follows The two cables are stretched obliquely towards the boat or the aircraft and the wing moves in the water, almost perpendicular to the cables because of its hydrodynamic lift and in the direction corresponding to the most taut The wing is stabilized in semi-immersion, roll and course by the tension of the cables, and in pitching by the beam 5 and its fins. The distribution of pressures on the submerged wing, with a wake resistance in the upper part, causes a 'nose-up torque' which raises the front wing above the water and applies the rear wing in hydroplaning to the water. The wing also takes in plan a positive incidence which places the curved ends of the ailerons in a position of skid favoring hydroplaning The wing meeting a wave and the front aileron touching the water, this positive incidence in plan, increased by lI shock, clears the aileron up without charging It avoids charging the beam 5
en la terminant par des relevés en ski. ending with ski surveys.
Par rapport au brevet précédent, le décalage " sous le vent " de la poutre 5 permet a la ligne des orgapes d'appui sur l'eau de se trouver à la verticale de la zone d'action de l'aile et ainsi de procurer une Compared to the previous patent, the offset "downwind" of the beam 5 allows the line of the support support organs to be vertical to the area of action of the wing and thus to provide a
meilleur régulation en incidence et en immersion, vis-a-vis de variations de l'angle de roulis. Ce décalage accroîit aussi la stabilité aux vagues. L'hydroplanage de l'aileron arrière donne une très faible traînée. better regulation in incidence and immersion, with respect to variations in the roll angle. This offset also increases wave stability. The hydroplaning of the rear wing gives a very low drag.
Le tube 5, d'un diamètre par exemple de l'ordre de 0,2 R, assure la flottabilité de l'ensemble en l'absence de traction sur les câbles, en une position qui procure le fonctionnement en dérive nautique dès l'apparition de la traction, dans un sens ou l'autre selon que le câble 4 ou le câble 4' est davantage tiré A grand vitesse, le tube 5, entièrement émergé, reçoit une vague de sillage issue obliquement de l'lntrados de l'aile en partie haute. Le pilote, sur le bateau ou l'aéronef, peut régler l'angle d'incidence par action différentielle sur les deux câbles, allant jusqu'à l'inversion de marche, de préférence après un ralentissement. On peut aussi utiliser un seul câble, attelé par exemple sur le milieu de l'aile et passant The tube 5, with a diameter for example of the order of 0.2 R, ensures the buoyancy of the assembly in the absence of traction on the cables, in a position which provides the operation in nautical drift from the appearance of the traction, in one direction or the other depending on whether the cable 4 or the cable 4 'is more pulled At high speed, the tube 5, fully emerged, receives a wave of wake coming obliquely from the lntrados of the wing in the upper part. The pilot, on the boat or the aircraft, can adjust the angle of incidence by differential action on the two cables, going up to the reversal of travel, preferably after a deceleration. You can also use a single cable, hitched for example on the middle of the wing and passing
par un anneau déplacé le long de la barre 3 par une télécommande. by a ring moved along the bar 3 by a remote control.
L'appareil ainsi deéfini manifeste une bonne stabilité. La finesse (rapport de la force sur les câbles à la traînée) est de l'ordre de 10, ce qui permet, avec un aéronef d'une finesse de l'ordre de 5 et un vent The device thus defined manifests good stability. The fineness (ratio of the force on the cables to the drag) is of the order of 10, which allows, with an aircraft of a fineness of the order of 5 and a wind
modéré, une vitesse considérable. moderate, considerable speed.
