Abstract

Przedmiotem zgłoszenia jest silnik magnetohydrodynamiczny, mający zastosowanie w laboratoriach fizycznych do celów badawczych i edukacyjnych. Silnik magnetohydrodynamiczny zawiera cylindryczne, przezroczyste, otwarte od góry naczynie (1), wykonane z materiału kwasoodpornego i przezroczystego, korzystnie z polimetakrylanu metylu i do dna tego naczynia jest przyklejona podstawa (2) w kształcie koła z umieszczonym centralnie otworem, w którym jest osadzony wspornik (3) w kształcie pręta, przechodzącego pionowo i zakończonego w górnej części stożkowym ostrzem (4). Nad ostrzem (4) znajduje się łożysko oporowe w kształcie krążka (5), mającego od dołu stożkowe zagłębienie, którego wierzchołek opiera się na ostrzu (4), zaś od góry łożysko oporowe (5) ma cylindryczne zagłębienie, a w nim jest osadzony dolny koniec pręta (6) z poziomą szczeliną w górnej części pręta i przechodzącym przez nią wskaźnikiem obrotu (7) w kształcie strzałki skierowanej poziomo. Łożysko oporowe (5) jest osadzone w otworze poziomej tarczy (8), do której został przyklejony od dołu magnes trwały (9) w kształcie pierścienia, namagnesowany w kierunku jego osi podłużnej i wykonany korzystnie ze spieku żelazo-neodym-bor oraz pokryty warstwą ochronną niklu. Na zewnętrznej, cylindrycznej powierzchni magnesu trwałego (9) jest osadzona anoda (10) w kształcie cienkościennego cylindra wykonanego z blachy ołowianej, zaś w otworze magnesu trwałego (9) jest osadzona tulejka izolacyjna (11), a w niej jest osadzona katoda (12) w kształcie cienkościennego cylindra wykonanego z blachy ołowianej, pokrytej tlenkiem ołowiu PbO<sub>2</sub>.The subject of the application is a magnetohydrodynamic engine used in physics laboratories for research and educational purposes. The magnetohydrodynamic engine contains a cylindrical, transparent vessel (1) open at the top, made of acid-resistant and transparent material, preferably polymethyl methacrylate, and a base (2) in the shape of a circle is glued to the bottom of the vessel, with a centrally located hole in which a bracket is embedded (3) in the shape of a rod, running vertically and ending in the upper part with a conical blade (4). Above the blade (4) there is a disc-shaped thrust bearing (5) with a conical recess at the bottom, the top of which rests on the blade (4), and from above the thrust bearing (5) has a cylindrical recess, in which the lower end is embedded bar (6) with a horizontal slot in the upper part of the bar and a rotation indicator (7) in the shape of a horizontally directed arrow passing through it. The thrust bearing (5) is embedded in the hole of the horizontal disc (8), to which a ring-shaped permanent magnet (9) has been glued from below, magnetized in the direction of its longitudinal axis and made preferably of iron-neodymium-boron sinter and covered with a protective layer nickel. On the outer cylindrical surface of the permanent magnet (9) there is an anode (10) in the shape of a thin-walled cylinder made of lead sheet, and in the hole of the permanent magnet (9) there is an insulating sleeve (11) and a cathode (12) in the shape of a thin-walled cylinder made of lead sheet, coated with lead oxide PbO<sub>2</sub>.
