Description

Anordning ved skipsskrog. Device at ship's hull.

Oppfinnelsen vedrorer en spesiell utformning av skipsskrog hvorved tilsiktes oppnådd.visse betydelige fordeler overfor skipsskrog utformet på kjent måte. Oppfinnelsen er særlig tenkt anvendt ved utformning av skroget for mindre, hurtiggående fartoyer som for eksempel motortopedobåter, -kanon-båter e.l., men kan også med fordel komme til anvendelse for andre fartoystyper som for eksempel hurtiggående ferger m.m.. The invention relates to a special design of a ship's hull, whereby it is intended to achieve certain significant advantages over ship's hull designed in a known manner. The invention is particularly intended to be used when designing the hull for smaller, fast-moving vessels such as motor topedo boats, gunboats etc., but can also advantageously be used for other types of vessels such as fast-moving ferries etc.

Hurtiggående fartoyer, særlig av de mindre typer vil i sjo-gang være utsatt for sterke påkjenninger og ubehagelige og uheldige bevegelser. Ved gang mot sjoen fås således ikke bare voldsomme stampébevegelser og meget overvann, men også kraftige slag av bolgetoppene mot fartdyets bunn. Ved sidesjo fås ofte slingrebevegelser eller overhalinger som i ekstreme tilfeller kan sette stabiliteten i fare. Slingrekjoler vil i uheldig grad redusere fartoyets manoverevne. Fast-moving vessels, especially of the smaller types, will be exposed to strong stresses and unpleasant and unfortunate movements when underway. When walking towards the sea, there are thus not only violent stampeding movements and a lot of storm water, but also strong blows of the wave crests against the bottom of the rapids. Side-viewing often results in wobbly movements or overtaking, which in extreme cases can endanger stability. Sling skirts will adversely reduce the vessel's manoeuvrability.

Ifolge oppfinnelsen foreslås det å utforme et skipsskrog av trimarantype, hvor det midtre skrogparti strekker seg ned til et dybdenivå under sideskrogenes og der er avsluttet med en . avrundet vulst således at det midtre skrogparti har en vesentlig mindre lengdeutstrekning enn sideskrogene, idet det er avsluttet et stykke foran skipsskrogets akterende. According to the invention, it is proposed to design a ship's hull of the trimaran type, where the middle hull section extends down to a depth level below the side hulls and is terminated with a . rounded bead so that the middle hull section has a significantly smaller length than the side hulls, as it ends a short distance in front of the stern of the ship's hull.

Ved en foretrukket utforelse har den avrundede vulst form av et torpedolignende legeme, hvis forreste ende rager fritt frem fra forbindelsen med hovedskroget. In a preferred embodiment, the rounded bead has the shape of a torpedo-like body, the front end of which projects freely from the connection with the main hull.

Vulsten eller det torpedoformede legeme ifolge oppfinnelsen vil således befinne seg på storre dybde enn skrogets bunn forovrig. Ved gang i sjo vil dette legeme stort sett alltid bevege seg gjennom vannet uten å loftes ut av dette selv ved kraftige stampébevegelser av fartoyet. Dette bevirker at sjo ikke vil kunne slå mot skrogets bunn slik som tidligere, samtidig som legemets oppdrift motvirker at baugen graver seg ned i sjoen. Ved at legemet forsynes med midler slik at det oppdeles i trimtanker resp. brennstofftanker kan fartoyets gang i sjoen juste-res til det fordelaktigste. The bead or the torpedo-shaped body according to the invention will thus be at a greater depth than the bottom of the hull otherwise. When sailing, this body will almost always move through the water without being lifted out of it, even with strong pounding movements of the vessel. This means that the boat will not be able to hit the bottom of the hull as before, while the buoyancy of the body prevents the bow from digging into the sea. By supplying the body with means so that it is divided into trim tanks or fuel tanks, the vessel's course in the sea can be adjusted to the most advantageous.

Forbindelsen mellom vulsten eller det torpedoformede legeme og skrogets bunn strekker seg kun over en del av dets lengde. Dermed vil fartoyets dreinirigsdiameter ikke vesentlig okes og fartoyet får god manoverevne. Ved at legemet er torpedoformet blir vannmotstanden beskjeden. Forbindelsen med skrogets bunn skjer videre ved et parti som er relativt smalt slik at torpedof-eller dråpeformen for legemets overflate ikke vesentlig avbry-tes. The connection between the bead or torpedo-shaped body and the bottom of the hull extends only over part of its length. Thus, the vessel's turning rig diameter will not be significantly increased and the vessel will have good manoeuvrability. Because the body is torpedo-shaped, water resistance is modest. The connection with the bottom of the hull further takes place at a section that is relatively narrow so that the torpedo or teardrop shape of the body's surface is not significantly interrupted.

Ved sidesjo tjener legemet og dettes forbindelsesparti til i skrogets bunn som er meget effektiv slingrekjol uten at man- When viewed from the side, the body and its connecting part serve as the bottom of the hull, which is a very effective swing skirt without man-

overevnen blir vesentlig dårligere. the upper ability becomes significantly worse.

Inne i legemet kan videre <q>m onskelig anordnes utstyr som hydro-foner e.l. Disse vil da få en meget gunstigere posisjon enn tidligere ved at de blir liggende på en vesentlig storre dybde. Equipment such as hydrophones or the like can be arranged inside the body if desired. These will then be in a much more favorable position than before, as they will lie at a significantly greater depth.

Ved å anordne legemet således at det omfatter trimtanker fås ikke bare mulighet for justering av trimmen for gunstig gang i sjo, men også for oppnåelse av den hoyeste fart. By arranging the body in such a way that it includes trim tanks, it is not only possible to adjust the trim for favorable sailing, but also to achieve the highest speed.

Det nedadragende legeme vil også virke som en bolgedemper The downward pulling body will also act as a shock absorber

for sjo som slår mot fartoyet fra en hvilken som helst retning, særlig når fartoysskroget under hoy fart lofter seg delvis opp av vannet. for waves that hit the vessel from any direction, especially when the vessel's hull lifts partially out of the water at high speed.

Til bedre forståelse av oppfinnelsen vises det til tegningene, hvor: Fig. 1 viser sett fra siden og rent skjematisk et fartoy utformet ifolge oppfinnelsen. For a better understanding of the invention, reference is made to the drawings, where: Fig. 1 shows from the side and purely schematically a vessel designed according to the invention.

Fig. 2 viser samme fartoy sett perspektivisk noe aktenfra. Fig. 2 shows the same vessel seen in perspective somewhat from the stern.

I det viste eksempel er det torpedolignende legeme betegnet In the example shown, the torpedo-like body is designated

A og rager ned fra bunnen nær ved fartoyets baugparti. A and projects down from the bottom near the vessel's bow.

;Midt- og akterskipet B er i eksemplet utformet som et katamaran-skrog og sammen med baugpartiets C nedadragende legeme A fås således en modifisert trimarankonstruksjon. In the example, the middle and stern ship B is designed as a catamaran hull and, together with the bow section C's downward pulling body A, a modified trimaran construction is thus obtained.
