Abstract

Przedmiotem zgłoszenia jest model silnika odrzutowego, przeznaczony do pokazów zjawiska odrzutu i mający zastosowanie do celów edukacyjnych. Model silnika odrzutowego zawiera podstawę (1) w kształcie kołowej, poziomo usytuowanej płyty i w środku podstawy (1) jest otwór, w którym jest wklejony dolny koniec pionowej osi (2), mającej górny koniec w kształcie stożkowego ostrza, wchodzącego do stożkowego zagłębienia łożyska oporowego (3), w kształcie walca, przyklejonego do dolnej powierzchni płytki (4), mającej kształt koła i zamykającej górny koniec tulejki (5), której dolny koniec jest wklejony do otworu wykonanego w dnie cylindrycznego naczynia (6), zamkniętego szczelnie od góry pokrywką (7), w kształcie koła zaopatrzonego na brzegu w kołnierz z gwintem wewnętrznym. Pokrywka (7) jest wkręcona na górną część bocznej powierzchni cylindrycznego naczynia (6), zaopatrzoną w gwint zewnętrzny. Górny koniec tulejki (5) kończy się pod pokrywką (7). W górnej części powierzchni bocznej cylindrycznego naczynia (6) są wykonane dwa naprzeciwległe otwory, w które są wklejone jedne końce dwóch dysz (8, 9), mających kształt rurek zagiętych pod kątem prostym. Zgięte części dysz (8, 9) są skierowane w przeciwne strony. Podstawa (1), oś (2), łożysko oporowe (3), płytka (4), tulejka (5), cylindryczne naczynie (6) i pokrywka (7) są współosiowe. Na dnie cylindrycznego naczynia (6) są umieszczane kawałki pokruszonej kredy (10), używanej do pisania na tablicy, zalane octem spirytusowym (11), używanym do celów spożywczych.The subject of the application is a jet engine model intended for demonstrations of the jet phenomenon and for educational purposes. The jet engine model comprises a base (1) in the form of a circular, horizontally arranged plate, and in the center of the base (1) is an opening into which the lower end of a vertical axis (2) is glued, having an upper end in the form of a conical blade, extending into the conical recess of a cylindrical thrust bearing (3), glued to the lower surface of the plate (4), in the form of a circle and closing the upper end of a sleeve (5), the lower end of which is glued into an opening made in the bottom of a cylindrical vessel (6), tightly closed at the top by a circular lid (7) provided with a collar with an internal thread at the edge. The lid (7) is screwed onto the upper part of the side surface of the cylindrical vessel (6), provided with an external thread. The upper end of the sleeve (5) terminates under the lid (7). In the upper part of the side surface of the cylindrical vessel (6), two opposing holes are made, into which one end of two nozzles (8, 9) are glued, shaped like tubes bent at right angles. The bent parts of the nozzles (8, 9) point in opposite directions. The base (1), axle (2), thrust bearing (3), plate (4), sleeve (5), cylindrical vessel (6), and lid (7) are coaxial. Pieces of crushed chalk (10), used for writing on a blackboard, doused with spirit vinegar (11), used for food purposes, are placed at the bottom of the cylindrical vessel (6).
