Abstract

The appliance comprises an elastic cover with changeable parameters referenced to ship frame I. The cover 2 is made of ferromagnetic rubber. The main electromagnet is positioned under cover 2 and connected to the modulator 5 via a voltage regulator 4. The modulator is connected to a speed transducer 6, rate generator 7 and excitation electromagnet 8, which interacts with front ship cover 2. Electric circuit board elements (voltage regulator 4, modulator 5 and generator 7) synchronize the operation of excitation electromagnet 8 and main electromagnet 3 according to the signal of the speed transducer 6, whereby the elements cause wave motion of ferromagnetic rubber cover 2, the rate of the wave motion coincide with the speed of the ship. Cover 2 wave movement pushes back water particles so water does not cohere with the surface of the ship and does not impede ship movement.

Nurodytas tikslas pasiekiamas tuo, kad žinomame įrenginyje laivo hidrodinaminėms savybėms pagerinti, tuLT 3496 B rinčiame kintančių laivo korpuso atžvilgiu parametrų elastingą dangą, padaryti tokie pakeitimai:The stated objective is achieved by making the following changes in the known device to improve the hydrodynamic properties of the vessel, the elastic coating of the variable parameters of the hull of the TuLT 3496 B:

elastinga danga padaryta iš feromagnetinės gumos su po ja išdėstytu pagrindiniu elektromagnetu, per srovės reguliatorių prijungtu prie moduliatoriaus, sujungto su judėjimo greičio davikliu, dažnumo generatoriumi ir žadinančiu elektromagnetu, sąveikaujančiu su priekinės laivo dalies danga.the elastic coating is made of ferromagnetic rubber with a main electromagnet placed beneath it, connected via a current regulator to a modulator connected to a motion sensor, a frequency generator and an excitation electromagnet interacting with the front coating of the vessel.

Autoriams nežinomi sprendimai su nurodytais naujais požymiais, todėl skaito, kad išradimas pasižymi esminiais požymiais.The authors are not aware of solutions with the above mentioned new features and therefore read that the invention has substantial features.

Išradimo esmė paaiškinta brėžiniu, kur I pav. pavaizduotas bendras įrenginio vaizdas pjūvyje, o 2 pav. jo elektros įrangos schema.BRIEF DESCRIPTION OF THE DRAWINGS FIG. Figure 2 shows a general view of the device in section; a diagram of its electrical equipment.

įrenginys sudarytas iš laivo korpuso I atžvilgiu kintančių parametrų elastingos dangos 2. Danga 2 padaryta iš feromagnetinės gumos. Po danga 2 išdėstytas pagrindinis - elektromagnetas 3, per srovės reguliatorių 4 prijungtas prie moduliatoriaus 5, sujungto su judėjimo greičio davikliu 6, dažnumo generatoriumi 7 ir žadinančiu elektromagnetu 8, sąveikaujančiu su priekinės laivo dalies danga 2.the device consists of an elastic coating 2 of variable parameters with respect to the hull I. The coating 2 is made of ferromagnetic rubber. Underneath the cover 2 is the main electromagnet 3, connected via a current regulator 4 to a modulator 5 connected to the motion speed sensor 6, a frequency generator 7 and an excitation electromagnet 8 interacting with the front cover 2.

Įrenginys veikia taip.The device works as follows.

Laivo greičio daviklis 6 fiksuoja laivo judėjimo greitį ir perduoda formuojantį signalą į moduliatorių 5, kuris veikia dažnuminės moduliacijos principu ir keičia dažnumo generatoriaus 7 signalą, .ir šio signalo valdomo žadinančio elektromagneto 8 skleidžiamos elektromagnetinės bangos sužadina feromagnetinės gumos dangą 2, todėl jos paviršiumi ima sklisti skersinės bangos. Bangų sklidimo greitis lygus laivo korpuso I judėjimo greičiui, o kryptis priešinga laivo judėjimui. Kad šios bangos nebūtų gęstančios, srovės reguliatorius 4 į pagrindinį elektromagnetą 3 perduoda žadinančio elektromagneto 8 dažnumą atitinkančią srovę ir tokiu būdu užtikrina bangų rezonansą nuo žadinančio elektromagneto 8 per visą dangą 2 nuo priekio iki laivugalio. Pasikeitus laivo judėjimo greičiui, daviklis 6 pakeičia moduliatoriaus 5 formuojamų signalų dažnį. Judėjimo greičiui padidėjus, didėja ir moduliatoriaus 5 išėjimo signalų dažniai. Dėl to žadinantis., elektromagnetas 8 priverčia dangos 2 paviršiumi sklisti didesnio dažnio, o tuo pačiu ir didesnio greičio skersines bangas. Srovės reguliatorius 4 padidina pagrindinio elektromagneto 3 maitinimo srovę, elektromagnetinio lauko įtampa padidėja, priversdama feromagnetinės gumos dangą 2 susispausti pagal naują skersinių bangų dažnį, atitinkantį rezonanso sąlygas ir užtikrinantį naujo dažnumo bangų sklidimą per korpusą I nuo priekio iki laivugalio. Laivo greičiui mažėjant, tokiu pat būdu nuo daviklio 6 signalo bangų dažnis sumažinamas. Tokiu būdu sąlygoms pasikeitus, sistema prisitaiko prie naujų sąlygų.The vessel speed sensor 6 captures the vessel's velocity and transmits a shaping signal to a modulator 5 which operates on the principle of frequency modulation and modifies the signal of the frequency generator 7. The electromagnetic waves emitted by the electromagnet 8 controlled by this signal excite the ferromagnetic rubber coating 2. transverse waves. The speed of wave propagation is equal to the velocity of movement of the hull I, while the direction is opposite to the movement of the vessel. To prevent these waves from being extinguished, the current regulator 4 transmits a current corresponding to the frequency of the excitation electromagnet 8 to the main electromagnet 3, thereby providing wave resonance from the excited electromagnet 8 through the entire coating 2 from the front to the aft. When the speed of the vessel changes, the transducer 6 changes the frequency of the signals produced by the modulator 5. As the movement speed increases, the modulator 5 output signal frequencies also increase. As a result of this excitation, the electromagnet 8 causes the surface of the coating 2 to propagate transverse waves of higher frequency and thus higher velocity. The current regulator 4 increases the supply current of the main electromagnet 3, the electromagnetic field voltage being increased, forcing the ferromagnetic rubber coating 2 to compress under a new transverse wave frequency corresponding to the resonance conditions and providing a new frequency wave propagation through the hull I from the anterior. As the speed of the ship decreases, in the same way the signal frequency of the transducer 6 is reduced. As the conditions change, the system adapts to the new conditions.

Lyginant su prototipu siūlomas įrenginys vandens pasipriešinimą laivo judėjimui sumažina tuo, kad, delfino odos veikimo principu, judant laivui bet kokiu greičiu, povandeninės laivo korpuso dalies paviršiumi sklinda bangos atitinkančios aptekančio vandens srauto greitį. Tai vandens srauto daleles paverčia judėti statmena bangų sklidimui kryptimi, jos nesukimba su korpuso paviršiumi ir nuslenka nuo jo nestabdydamos laivo judėjimo, naikindamos trintį tarp vandens ir laivo paviršiaus. Tai užtikrina žadinantis elektromagnetas laivo priekyje bei pagrindinis elektromagnetas, išdėstytas po visa feromagnetine danga, ir elektros įrangos schema, suderinanti sinchronišką šių elektromagnetų darbą.Compared to the prototype, the proposed device reduces the water resistance of the ship's motion by the fact that, under the principle of dolphin skin operation, the ship propagates waves corresponding to the velocity of flowing water at any speed when moving the ship. This causes the water flow particles to move in a direction perpendicular to the propagation of the waves, they do not adhere to and slide away from the hull surface without stopping the vessel's movement, eliminating friction between the water and the vessel's surface. This is achieved by the excitation of the electromagnet at the front of the ship and the main electromagnet under the ferromagnetic coating and the circuitry of the electrical equipment, which harmonize the synchronous operation of these electromagnets.
