Project summary

Figure 1 schematically shows the proposed engine; figure 2 is a view A in figure 1; figure 3 is a section BB in figure 2; figure 4 - connection of wire segments by springs; figure 4 - connection of wire sections in the form of couplings using springs.

The proposed engine contains a housing 1, on the racks 2 of which two, respectively, drums 3 and 4 are installed in parallel with the possibility of rotation with a ratio of their diameters of 1.5 - 5, between which there are a heater 5 and a cooler 6 and on which a working fluid is installed in the form of metal wires 7 with a diameter of 0.05 - 3 mm, which are tensioned on drums 3 and 4 and which have the ability to engage with drums 3 and 5 due to the entry of springs 9 into grooves 8 of drums 3 and 4, connecting pieces of these metal wires 7 into closed couplings, and wound in the form of cones turned to each other by the bases, made powerful and these couplings pass through the heater 5 and the cooler 6 through the slots 10 made in them, the posts 2 of one of the drums 3 and 4 are connected with the hinges 11 to the body 1 and are supported relative to the body 1 in the direction of tension springs 9 couplings of wire 7 with screws 12 screwed into these posts 2, there is a device (not shown in the drawing) that supplies heat to the heater 5 when When the driving drum rotates at a speed of 1000 rpm, these wires 7 are made in the form of springs 13 from an alloy that has the ability to change its shape depending on its heating and the turns of the wire 7 are formed at low temperatures.

The proposed engine works as follows, the starter (not shown in the drawing) rotates one of the drums 3 and 4, they both rotate, since they are connected by wires 7 through the springs 9 located in the grooves 8, when this rotation reaches a speed of 1000 rpm heat is supplied to the heater 5 by the device (not shown in the drawing), this leads to the fact that the tension of the wires 7 in the section of the heater 5 becomes less due to the thermal elongation of the wires 7 and the balance of the tension forces of both branches of the wires 7 is disturbed, which creates a torque, the high stiffness of the springs 9 allows the generated power of the engine to effectively respond even to small thermal elongations of the wires 7 and to be large, which provides a large torque of the engine, shown by arrows in Figs. 2 and 3. Before starting the engine, the position of the screws 12 is at the smallest tension of the wires 7 through the stretching of the springs 9, during the starting process and with further engine operation, the engine power is regulated by the fuel supply and the rotation of the screw 12
