FIG. 12A is an output characteristic diagram of a cylindrical power generator having eight holes and eight pole thin plate magnets in a tube, FIG. 12A is an output frequency characteristic diagram with respect to time, and FIG. FIG.

  First, in FIG. 9, the power generation unit B includes an acrylic pipe (outer diameter 40 mm) 71 disposed at the center of the rotating body, a sponge ring 72 disposed at the outer periphery of the acrylic pipe 71, and an outer periphery of the sponge ring at predetermined intervals. 4-pole thin plate magnet (10 mm × 20 mm × 2 mm, 0.23T) 73, buffer sponge (5-10 mm × 5-10 mm, thickness is 1-2 mm) 74, aluminum tube (outer diameter 70 mm, It has an inner diameter of 64 mm and a height of 10 mm) 75, and holes (diameter 3 mm) 76 formed in the aluminum tube 75 at eight positions at predetermined intervals.

  77 and 78 are nozzles, and the two nozzles 77 and 78 are arranged to face the side surface of the rotating body.

  In FIG. 10A, an aluminum tube (outer diameter 70 mm, inner diameter 64 mm, thickness 10 mm) has eight holes and a quadrupole thin permanent magnet, and a structure in which a sponge ring is filled inside has eight holes. In the case of holes, it exceeded 400 Hz in a short time (not 15 seconds) [in the case of four holes, it exceeded 380 Hz in a short time (not 15 seconds)]. Similarly, in FIG. 10B, in the case of 8 holes and 8 poles of a thin plate permanent magnet in the aluminum tube, 0.11 (V) at maximum was recorded in a short time (not 10 seconds). In the case of a thin plate permanent magnet with 8 holes and 4 poles in the aluminum tube, a maximum of 0.115 (Hz) could be output in a short time (not 20 seconds).

  Next, in FIG. 11, the power generation unit B includes an acrylic pipe (outer diameter 50 mm, inner diameter 40 mm, height 10 mm) 81 arranged at the center of the rotating body, and a sponge ring (outside) arranged at the outer periphery of the acrylic pipe 81. 64 mm diameter, 50 mm inner diameter, 10 mm thickness) 82, 8-pole thin plate magnet (10 mm × 20 mm × 1 mm, 0.18T) 83 arranged at predetermined intervals on the outer periphery of the sponge ring 82, an aluminum tube (outer diameter 70 mm, It has an inner diameter 64 mm, a height 10 mm) 84, and holes (diameter 3 mm) 85 formed in the aluminum tube 84 at eight predetermined intervals.

  86 and 87 are nozzles, and the two nozzles 86 and 87 are arranged to face the side surface of the rotating body.

  In FIG. 12 (a), in the case of using a nozzle by an air compressor (low pressure 2 port maximum pressure 0.3 MPa) with 8 holes and 8 pole thin plate magnets (0.14T) in an aluminum tube, Output at maximum 860 (Hz) in less than 20 seconds, and output at maximum 760 (Hz) in a short time (not in 25 seconds) when using a nozzle with an air compressor (low pressure 2 port maximum pressure 0.25 MPa) I was able to.

  Note that the air pressure used for the propulsive force exceeds the unstable region (2000-3000 rpm for the current rotating body) that depends on the natural vibration, and a high pressure (0.25 MPa or more in this test) is obtained until a stable high-speed rotation is obtained. Although necessary, it is considered possible to reduce the pressure when entering the high speed range.

  Here, even if the material was changed from an acrylic pipe to an aluminum pipe and the deformation of the material of the power generation part (rotation mechanism part) was eliminated, it was considered that the influence of the expansion and contraction of the material was small, As long as the material has a strength capable of avoiding breakage from the rotating centrifugal force, minute expansion and contraction may be added to the self-control function by the centrifugal force of itself or wind force.

  Further, it is clear from the test of the power generation unit shown in FIGS. 4 and 9 that the size of the buffer sponge cannot be limited, and the gas injected from the nozzle is decelerated by the buffer sponge, and the power generation unit B It is thought that the balance is taken within.

(A) is the state which has stopped, FIG.13 (b) is a figure which shows the state which is rotationally driving.

  The cylindrical power generator having a two-pole shaft rotating body levitated by this high-temperature superconductor is a magnetic levitated rotating body 91 in which a strip-like external sponge 93 is fixed to the outer periphery of an aluminum tube 92. In the aluminum tube 92, quadrupole magnets (not shown) are arranged at predetermined intervals, and the aluminum tube does not need to have holes as in the above-described embodiment.

  If comprised in this way, the structure of a rotary body can be simplified very much. However, it is necessary to fix the strip-like external sponge 93 firmly so as not to peel off. For this purpose, it is desirable to bak and form a porous amorphous material.

  FIG. 14 is an output characteristic diagram of a cylindrical power generator having a four-pole thin plate magnet having an external sponge on an aluminum tube according to another embodiment of the present invention, and FIG. FIG. 14B is a frequency characteristic diagram and FIG. 14B is an output voltage characteristic diagram with respect to time.

  The first to fourth experiments are conducted, and it can be seen that the output gradually increases from the first and the highest output is obtained in the fourth. Incidentally, in FIG. 14A, the rotation speed (Hz) with respect to time approaches 450 (Hz) at the maximum, and in FIG. 14B, the output voltage (V) with respect to time reaches 0.16 (V) at the maximum. ) Is exceeded.

A porous member (sponge) having a self-controllable function and a nozzle for blowing the propelling gas are provided.

In the above embodiment, a sponge is used as a part of the members. However, considering the ultra high speed rotation, it is desirable to change to the following members.
(1) Fill the plastic bead assembly.
(2) A plastic assembly path is formed in the segment magnet.
(3) A gas path is formed by a laminated structure of magnet-plastic assembly-magnet. In that case, for example, a fiber-reinforced plastic substrate bonding method (see Patent Document 3) can be used.
(4) A supporting structure frame (for example, a spoke structure) is used.

  In addition, the Navier-Stokes general solution has not yet been proved in the academic verification of self-control. However, from the basics of fluid mechanics, from the law of conservation of mass, the law of conservation of energy, Bernoulli's formula, Navier-Stokes formula, subtle fluctuations in the fluid in the control volume surrounded by the control surface (control surface). Obviously, it is impossible to obtain continuous rotation at high speed without self-control.

  Since it comprised in this way, while being able to simplify the structure of an electric power generation part, the rotation propulsion apparatus of the magnetic levitation-type generator which performs ultra high-speed rotation which reaches 10,000 rotation speed was realizable.

  In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.

  The magnetic levitation-type rotary propulsion device of the present invention can be used as a rotary propulsion device for a magnetic levitation generator with a simplified structure and capable of ultra-high speed rotation.
