Description of the Invention: [Technical Field] The present invention relates to a compression fan inside a jet engine, which uses a plurality of intersectingly extending blades to generate an annular passage that is gradually compressed from top to bottom, and compresses the air and air. To increase the compression ratio and internal pressure into the combustion chamber, the engine thrust is increased and the fuel economy is achieved. [Prior Art] _ Press, the traditional jet engine structure, as shown in the first figure, is a jet engine 1 for a conventional model aircraft, the front end is provided with a starter motor n, and is connected with a compression fan 12' and located in the casing 1 The internal engine components (not shown) are conventional structures and therefore will not be described. As for the setting of the compression fan 12, the air is mainly compressed into the engine room to enhance the explosive power of the ignition. The fan structure currently used is derived from the car turbocharger, which is still low speed. When the engine reaches a certain speed (rpm), the pressure of the casing will not be able to increase. It is necessary to rely on a high amount of fuel oil, so the fan is prone to damage and the effect is not good as it runs at high speed. Please refer to the second perspective view of the conventional compression fan 12, which is a ring-shaped, centrally formed with a shaft center 120, and has a shaft hole 121' and is provided by the top end of the shaft hole (10). There are a plurality of separators 13 which can divide the compression fan 12 into a plurality of air passages 13 which are gradually enlarged from top to bottom. The air passage 13G having a larger bottom end is provided with a plurality of guide pieces 131 which are divided into a plurality of divided passages 132. In use, the compression fan 12 is activated by the starter motor u (refer to the first figure), and the air is compressed into the air duct 201122232 130 by the partition piece 13 and separated by the guide piece 131 by the bottom larger air duct 130. The air is diffused by the lanes 132 and sent to the engine to expand and ignite the explosion to generate power, which can propel the aircraft. Although the conventional compression fan 12 can be used on the jet engine of the model aircraft, there are a lot of practical use missing: (1) The conventional compression fan 12 series is designed for low-speed car vortex-supercharged engines' so when used In the high-speed jet engine, the compression is relatively small, so that higher thrust cannot be generated. (2) The traditional Wei fan 12 leaf > 5 angle is large, when the air is continuously entering the machine clamp, the internal pressure will be generated, and when the pressure inside the machine clamp is increased to saturation, the engine will be accelerated at this time. The compressed air of the clamp does not increase the air pressure of the clamp due to the increase in the rotational speed. As for the increase of the speed, it must rely on the increase of the oil. 'At this time, the amount of gas entering the machine is equal to the amount of air that is sprayed out.' Therefore, the pressure of the machine clamp depends on the design of the fan. The jet engine used in countries around the world _ fans, compression The ratio is small, so the engine thrust cannot be produced. (3) When the 12 lions are pressed against the fan, the pushing force generated by the pushing air (vertical pulling force) is small, but because the distance between the separators 13 and the angle cannot be averaged °, when the south speed is running, the left and right torque is large and easy. Damage occurred. (4) When the torque of the fan 12 is too large, the suction will be unbalanced, so the left red ship will be more A, and the load will be broken. Beizhan+Inventors have been determined to use the fan of the traditional (4) fan and are unable to meet the determination of the germination reform. With their own professionalism and years of experience in 201122232, they have undergone several trials, revisions and improvements. Finally, the invention was first created. SUMMARY OF THE INVENTION The present invention is directed to a new design of a compression fan for a jet engine that is a new design for a compression fan of a model aircraft or a jet engine for an automobile. It is mainly formed by a spiral fan with an axis at the center and a shaft hole. And the shaft to the top are equidistantly provided with a plurality of leaves and spirally intersecting to the bottom end of the shaft. The spiral blade forms a plurality of spiral passages, and is gradually tapered from top to bottom, and can gradually compress the air into the engine room. . As for the wind (four) of each blade is small, the speed of the air is slow, but the pressure of the air is raised and the blades are perpendicular to the axis. The smoothness is high and the left and right yaw is small. It does not cause too much imbalance. As for the process air brought in by the fan blade, the spiral air passage can generate a higher air compression ratio and then enter the engine room. By burning at a high temperature, the volume is rapidly expanded. The ability to produce 'can effectively save fuel consumption, and indeed improve the engine to push the power. [Applying method] An axial center 21 is formed in the center of the fan 2. First, as shown in the second figure, the stereoscopic appearance of the present invention is

When the compression fan 2 is running, the starting point of each blade 22 is almost parallel with the wind cutting. Therefore, the two adjacent leaves=22 spiral channels 22〇 will be In the state of no resistance, the air is brought into the screw channel 220, and through the tapered spiral channel 22〇 (shown in the fourth figure), the gas is sent down to the bottom end, and the fifth figure is matched. As shown in another perspective view of the present invention, the blade 22 of the compression fan 2 extends from the top end of the shaft core 21 to the bottom end, so that the spiral passage 22 is tapered to the lowermost end, that is, sent out by each outlet 221, and Entering the engine and continuously compressing air into the engine room's, it can more than double the driving force compared to the traditional engine of the same size. Moreover, the side of each of the blades 22 can be arranged in a straight line 23 (as shown in FIG. 6), or in the form of a diagonal line 24, or even a curve, which is completely designed according to requirements, so that the following advantages are apparent in use: C) The invention is completely in accordance with the design of high speed. Therefore, the blade has a high compression ratio as the speed is increased, and can withstand high thrust. (2) The blade 22 of the invention has a small wind cutting angle, and continuously compresses the air volume into the engine, so that the explosive force generated is large, and the driving force can be increased and the oil can be saved, thereby achieving the purpose of environmental protection, energy saving and carbon reduction. (2) The blade 22 of the present invention has a small air-cut angle, a small left-right torsion force during rotation, a relatively uniform suction force, and no yaw of the blade 22. (4) The smaller the yaw degree of the blade 22 is, the lighter the load of the bearing is, and the rotation is smoother, which can prolong its service life. In addition, the shaft 21 of the present invention has a tapered shape, and the spiral passage 22 is tapered downward from the top end of the shaft to continuously compress the cut air into the engine room. Of course, the shaft 21 can also be up and down. The design, although the compression effect is poor, can still achieve the purpose of continuously compressing air into the engine room. Further, the leaf 22 extends downward from the top end of the shaft core 21 to the bottom end, and the shape of the blade can be changed in accordance with the shape of the engine, so that the effect of the compressed air can be produced as long as the spiral passage 22 is formed. According to the invention, the blade is improved in the blade to make the blade air-cut angle smaller, the intake air amount is increased, and the left and right yaw degrees are slowed down, so that the blade rotates smoothly and is not easily damaged, and the health-care material reaches the ring contact. The effect of energy can be more advanced than traditional blades, and the application for the approval of the same product before the application of the patent has been in line with the requirements of the patent, and the patent application is filed according to law.
