Description

PROPULSIÓN MARINA EQUILIBRADA BALANCED MARINE PROPULSION

SECTOR NA V AL NA V AL SECTOR

ESTADO DE LA TÉCNICA: La propulsión a motor en embarcaciones se ha ubicado siempre a la popa de estas. Solamente se utilizan motores de proa con finalidades de control de la embarcación, de manera transversal a la embarcación. La ubicación de la fuerza motriz en la popa provoca, ademas de la propulsión, un aumento del desplazamiento como efecto secundario. La embarcación se empopa y se hace necesario sistemas de equilibración (flaps o power trim). Este aumento del desplazamiento lo podemos considerar como una fuerza de resistencia . A partir de una velocidad (unos 5-7 nudos) hay una relación no lineal entre la potencia y la velocidad, de tal manera que hay que aumentar mucho la potencia para conseguir un poco mas de velocidad. Según el tipo de embarcación se consigue que a cierta velocidad esta planee, hay una reducción del desplazamiento, pero gracias a una elevada potencia. STATE OF THE TECHNIQUE: The motor propulsion in boats has always been located at the stern of these. Only bow motors are used for vessel control purposes, transversely to the vessel. The location of the driving force in the stern causes, in addition to the propulsion, an increase in displacement as a side effect. The boat is Empopates and balancing systems (flaps or power trim) are necessary. We can consider this increase in displacement as a force of resistance . From a speed (about 5-7 knots) there is a non-linear relationship between the power and speed, so you have to increase the power to get a little more speed. Depending on the type of boat you get that at a certain speed it is planned, there is a reduction in displacement, but thanks to a high power.

OBJETIVO: El objetivo de este sistema es conseguir una mayor eficiencia en la propulsión a motor en embarcaciones: OBJECTIVE: The objective of this system is to achieve greater propulsion efficiency at motor in boats:

una navegación cómoda entre ocho y doce nudos, sin que la embarcación este empopada. Utilizar motores de menor potencia (y permitan alcanzar velocidades de crucero de quince a veinte nudos), que nos reporte una mejora medioambiental (menos combustible). a comfortable navigation between eight and twelve knots, without the boat being empowered. Use engines of lower power (and allow reaching cruising speeds of fifteen to twenty knots), which will report an environmental improvement (less fuel).

El sistema consiste en situar los elementos propulsores justo delante del centro de gravedad( 1 ) . La fuerza propulsora tiende a elevar la embarcación, The system consists of placing the propellant elements just in front of the center of gravity (1). The propelling force tends to raise the vessel,

5 adquiere una componente vertical hacia la superficie que hace disminuir el desplazamiento de la embarcación. Debido a diferentes niveles de carga, varia la situación del centro de gravedad (2). Para conseguir un ajuste lo más próximo al centro de gravedad, se puede variar longitudinalmente la posición del motor mediante una guía del soporte 5 acquires a vertical component towards the surface that reduces the vessel's displacement. Due to different load levels, the situation of the center of gravity varies (2). To achieve an adjustment as close to the center of gravity, the position of the motor can be varied longitudinally by means of a support guide
