Abstract
EMBARCACIONES PLANEADORAS DE RENDIMIENTO MEJORADO, METODOS PARA MEJORAR DICHO RENDIMIENTO Y ALETAS HIDRODINAMICAS SUSTENTADORAS QUE PUEDEN ASOCIARSE CON EMBARCACIONES PLANEADORAS PARA AUMENTAR SU RENDIMIENTO. SOBRE LA EMBARCACION SE APLICA UNA FUERZA DESCENDENTE Y DINAMICA GENERADA AL MOVERSE LA EMBARCACION EN EL AGUA, PREFERENTEMENTE MEDIANTE UNA ALETA HIDRODINAMICA SUSTENTADORA (3). EL PUNTO DE APLICACION DE LA FUERZA ESTA SITUADO, EN EL SENTIDO TRANSVERSAL, EN EL PLANO LONGITUDINAL VERTICAL CENTRAL DE LA EMBARCACION. EN DIRECCION LONGITUDINAL, EL PUNTO DE APLICACION DE LA FUERZA DINAMICA ESTA SITUADO, EN RELACION A OTRAS FUERZAS QUE ACTUAN A LO LARGO DE LA EMBARCACION, PARA DISMINUIR EL ANGULO DE ASIENTO DE LA EMBARCACION AL MENOS DOS GRADOS. PARA EL FUNCIONAMIENTO EFICAZ Y ESTABLE EN ANGULOS BAJOS DE ASIENTO, EL INVENTO PROPORCIONA CONFIGURACIONES DE LA SUPERFICIE HUMEDECIDA DE LA EMBARCACION, QUE INCLUYEN LAS SIGUIENTES: UNA PARTE FINA (32) DESDE LA RODA HASTA LA REGION CENTRAL CILINDRICA DE CALADO PROFUNDO QUE MINIMIZA EL ASCENSO DE LA PROA QUE TIENE LUGAR CON LAS EMBARCACIONES PLANEADORAS CONVENCIONALES Y AYUDA AL MANTENIMIENTO DE LA LAMINARIDAD DE LA CIRCULACION EN LAS SUPERFICIES DE PLANEAMIENTO; UNA ALETA DE SUSTENTACION (31) QUE SE EXTIENDE A LO LARGO DE LA PROA POR DEBAJO DE LA LINEA DE FLOTACION Y ESPACIADA HACIA ADELANTE DE LA MISMA, DIRIGE DE FORMA AERODINAMICA EL FLUJO QUE PASA POR LA PROA, DISMINUYENDO ASI LA ESPUMA Y LA TURBULENCIA; UN TALON DE QUILLA (32) QUE SE EXTIENDE HACIA ABAJO EN LA PARTE INFERIOR DEL CASCO EN LA ENTRADA A LO LARGO DE UN PLANO CENTRAL LONGITUDINAL QUE MEJORA LA ESTABILIDAD DIRECCIONAL Y TAMBIEN AYUDA PARA MANTENER LA LAMINARIDAD DEL FLUJO; UN ALA EN FLECHA SITUADA EN LA ENTRADA, MONTADA PREFERIBLEMENTE EN EL MARGEN INFERIOR DEL TALON DE QUILLA, SITUADO CON UN ANGULO DE ATAQUE QUE GENERA UNA FUERZA ASCENDENTE QUE MEJORA LA ESTABILIDAD DE LA EMBARCACION FRENTE AL CABECEO Y LA GUIÑADA EN AGUAS AGITADAS; UN SUELO PLANEADOR (11) EN ELCENTRO DE LA EMBARCACION QUE ASCIENDE HACIA EL EXTREMO LIMITE DE LA POPA, DEL 50% AL 100% DEL CALADO DEL CENTRO DE LA EMBARCACION, QUE MEJORA LA ESTABILIDAD DE LA EMBARCACION CUANDO SE GOBIERNA EN ASIENTO; UN SUELO DE DESCARGA (21) QUE SE PROLONGA HACIA POPA DE UN 5 A UN 25% DE LA LONGITUD DE LA LINEA DE FLOTACION DE LA EMBARCACION, PREFERENTEMENTE DESDE UN ESCALON TRANSVERSAL (4) Y QUE SE ELEVA A TODO LO LARGO DE UN 10 A UN 50% RESPECTO AL CALADO DEL CENTRO DE LA EMBARCACION HASTA UN EXTREMO LIMITE TRANSVERSAL (22). EL EXTREMO POSTERIOR Y EL SUELO DE DESCARGA, EN DIRECCION TRANSVERSAL, SON PARALELOS AL PLANO DE BASE DE LA EMBARCACION. EL SUELO DE DESCARGA DE PRESION REDUCE LA PRESION EN LA CIRCULACION HACIA POPA, EFECTUANDO UNA SEPARACION EN EL EXTREMO POSTERIOR DE FORMA GRADUAL Y UNIFORME QUE REDUCE LA RESISTENCIA AERODINAMICA. UNAS ARISTAS (12) EN LOS MARGENES DEL SUELO DE PLANEAMIENTO DE POPA LLEVAN ALETAS QUE SE PROLONGAN HACIA ATRAS Y HACIA ARRIBA DEL EXTREMO LIMITE DE LA POPA EFECTUANDO UNA SEPARACION SUAVE DEL FLUJO EN CIRCULACION. LA ALETA QUE GENERA UNA FUERZA DESCENDENTE DEL FLUJO EN CIRCULACION DEBE IR SITUADA POR DEBAJO DEL EXTREMO LIMITE DE LA POPA Y CONTORNEADA PARA PRODUCIR LA MINIMA RESISTENCIA INDUCIDA Y DESVIAR EL FLUJO EN SU EXTREMO POSTERIOR HACIA ABAJO A FIN DE REDUCIR LA TURBULENCIA Y LA RESISTENCIA EN LA POPA.IMPROVED PERFORMANCE PLANNING BOATS, METHODS FOR IMPROVING SUCH PERFORMANCE AND SUSTAINING HYDRODYNAMIC FINS THAT CAN BE ASSOCIATED WITH PLANNING BOATS TO INCREASE THEIR PERFORMANCE. ON THE VESSEL A DOWN AND DYNAMIC FORCE GENERATED AS THE VESSEL MOVES IN THE WATER, PREFERABLY THROUGH A SUSTAINING HYDRODYNAMIC WING (3). THE POINT OF APPLICATION OF THE FORCE IS LOCATED, IN THE CROSS-CUTTING DIRECTION, ON THE CENTRAL VERTICAL LONGITUDINAL PLANE OF THE VESSEL. IN A LONGITUDINAL DIRECTION, THE POINT OF APPLICATION OF THE DYNAMIC FORCE IS LOCATED, IN RELATION TO OTHER FORCES ACTING ALONG THE VESSEL, TO DECREASE THE SEAT ANGLE OF THE VESSEL BY AT LEAST TWO DEGREES. FOR EFFECTIVE AND STABLE OPERATION AT LOW SEAT ANGLES, THE INVENTION PROVIDES BOAT WET SURFACE CONFIGURATIONS, INCLUDING THE FOLLOWING: A FINE PART (32) FROM THE WHEEL TO THE CYLINDRICAL CENTRAL REGION OF CALIMUNDO DE PROFADO OF THE BOW THAT TAKES PLACE WITH THE CONVENTIONAL PLANNING CRAFT AND HELPS THE MAINTENANCE OF THE LAMINARITY OF THE CIRCULATION IN THE PLANNING SURFACES; A SUSTAINING FIN (31) THAT SPREADS ALONG THE BOW BELOW THE WATER LINE AND SPACED FORWARD THEM, DIRECTING THE FLOW AERODYNAMICALLY, DIMINISHING SO THE FOAM AND TURBULENCE ; A KELLE HEEL (32) THAT EXTENDS DOWNWARD IN THE BOTTOM OF THE HULL AT THE ENTRANCE ALONG A CENTRAL LONGITUDINAL PLANE THAT IMPROVES DIRECTIONAL STABILITY AND ALSO HELPS TO MAINTAIN THE FLOW LAMINARITY; A WING IN ARROW LOCATED AT THE ENTRANCE, PREFERABLY MOUNTED IN THE LOWER MARGIN OF THE KEEL HEEL, LOCATED WITH AN ANGLE OF ATTACK THAT GENERATES AN UPWARD STRENGTH THAT IMPROVES THE STABILITY OF THE BOAT IN THE WINKLING AND THE GUIÑADA IN AGUAS; A PLANNING FLOOR (11) AT THE CENTER OF THE VESSEL THAT RISES TOWARD THE EXTREME LIMIT OF THE AFTER, FROM 50% TO 100% OF THE DRAFT OF THE CENTER OF THE VESSEL, WHICH IMPROVES THE STABILITY OF THE VESSEL WHEN IT IS GOVERNED IN SEAT; A DISCHARGE FLOOR (21) THAT PROLONGS TOWARDS AFTER 5 TO 25% OF THE LENGTH OF THE FLOAT LINE OF THE VESSEL, PREFERABLY FROM A CROSS STAGE (4) AND THAT RISES TO ALL THROUGH A 10 50% WITH RESPECT TO THE STREET OF THE CENTER OF THE VESSEL UP TO AN EXTREME CROSS-CUTTING LIMIT (22). THE REAR END AND THE UNLOADING FLOOR, IN A CROSS-CUTTING DIRECTION, ARE PARALLEL TO THE BASE PLAN OF THE BOAT. THE PRESSURE DISCHARGE FLOOR REDUCES THE PRESSURE IN THE CIRCULATION TOWARDS AFT, CARRYING OUT A SEPARATION AT THE POST END IN A GRADUAL AND UNIFORM WAY THAT REDUCES AERODYNAMIC RESISTANCE. SOME EDGES (12) ON THE MARGINS OF THE AFT PLANNING SOIL HAVE FINS PROLONGING BACKWARDS AND UPWARDS THE EXTREME LIMIT OF THE AFT, MAKING A SMOOTH SEPARATION OF THE FLOW IN CIRCULATION. THE FIN WHICH GENERATES A DOWNFLOWING FORCE IN CIRCULATION MUST BE LOCATED BELOW THE EXTREME LIMIT OF THE AFT AND CONTOURED TO PRODUCE THE MINIMUM INDUCED MINIMUM RESISTANCE AND DIVERT THE FLOW IN ITS LAST DOWN TO REDUCE THE TURBENCE THE STERN.
