Precession Difference Engine Technical Field
[0001] This invention relates to the field of precession mechanics technology for aerospace propulsion and gyroscopes, and particularly to a precession differential engine. Background Technology
[0002] Rocket engines consume fuel, and the limited fuel of rockets will eventually run out, making it impossible to travel freely in space without worrying about fuel. Utilizing the difference between the precession direction of the flywheel and the rotation direction of the outer frame to generate thrust is a better alternative to rockets. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a precession difference engine, which generates precession by rotating the base (11), connecting rod (8) and flywheel (2) at high speed. The direction of precession of the flywheel (2) is different from the rotation direction of the outer frame (5), thereby generating thrust, so that the propulsion body (15) propels the spacecraft to fly continuously in the universe.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A precession differential engine, characterized in that: the precession differential engine includes a thruster body (15) stationary in a vacuum weightlessness state, the thruster body (15) has 4 gyroscope compartments (1) inside, the thruster body (15) is equipped with a main motor (13), the output shaft of the main motor (13) extends into the gyroscope compartment (1) and is connected to the outer frame (5), the output shaft of the main motor (13) is equipped with an outer conductive slip ring (12), the outer frame (5) is equipped with an inner frame drive motor (3) and an inner frame (6), the inner frame drive motor (3) and the inner frame (6) are connected together, the output shaft of the inner frame drive motor (3) is equipped with a central guide An electric slip ring (4) is provided. A base drive motor (9) is mounted on the inner frame (6). An inner conductive slip ring (10) is mounted on the output shaft of the base drive motor (9). A base (11) is mounted in the middle of the output shaft of the base drive motor (9). Multiple connecting rods (8) are mounted on the base (11). A flywheel motor (7) is mounted at the end of the connecting rod (8). A flywheel (2) is mounted on the outside of the flywheel motor (7). The wire (14) passes through the outer conductive slip ring (12), the middle conductive slip ring (4), and the inner conductive slip ring (10) to provide power and transmit control signals to the main motor (13), the inner frame drive motor (3), the base drive motor (9), and the flywheel motor (7).
[0006] In order to make the direction of the precession deformation of the connecting rod (8) different from the rotation direction of the outer frame (5), the connecting rod (8) is made of elastic material, so that when the connecting rod (8) is driven to rotate at high speed by the base (11), it can deform upward due to the precession of the flywheel (2).
[0007] In order to change the rotation plane of the connecting rod (8) and the base (11) and the advance direction of the flywheel (2), the inner frame (6) is driven to rotate by the inner frame drive motor (3).
[0008] To increase the advance torque and make the advance torque continuous, the base (11) has multiple connecting rods (8) and a flywheel (2).
[0009] In order to make the rotation direction of the outer frame (5) different from the advance direction of the connecting rod (8) and the flywheel (2), the outer frame (5) is driven to rotate by the main motor (13).
[0010] In order to increase thrust and maintain balance to prevent rotation caused by thrust asymmetry, multiple gyroscope cabins (1) are symmetrically arranged on the outside of the thruster body (15).
[0011] In order to ensure that the position where the flywheel (2) has a different direction of advance and the rotation direction of the outer frame (5) are always on the same side, the outer frame (5) and the inner frame (6) rotate at the same speed.
[0012] In order to reduce the running resistance when the flywheel (2), connecting rod (8), outer frame (5) and inner frame (6) rotate, the gyroscope cabin (1) is a vacuum environment.
[0013] In order to achieve the steering and change of motion direction of the propeller body (15), the rotational speed difference is generated by adjusting the rotational speed of the outer frame (5) and the inner frame (6), so that the position where the precession direction of the flywheel (2) differs from the rotational direction of the outer frame (5) changes, thereby changing the direction of thrust.
[0014] In order to generate thrust and accelerate the propulsion body (15), inside the gyroscope cabin (1), when the outer frame (5) drives the base (11) and flywheel (2) to rotate, the flywheel (2) on the left side of the base (11) has the same direction of advance as the outer frame (5) and the direction of rotation of the two forces with the same direction superimposes on each other. The flywheel (2) on the right side of the base (11) has the opposite direction of advance as the outer frame (5) and the two forces with opposite directions cancel each other out. When the outer frame (5) drives the base (11) and flywheel (2) to rotate, the flywheel (2) on the right side of the base (11) requires more force than the flywheel (2) on the left side of the base (11), so that the reaction force obtained on the right side of the base (11) is greater than the reaction force obtained on the left side of the base (11). The two reaction forces with opposite directions cancel each other out and generate a new resultant force. The direction of the resultant force is the direction of the thrust.
[0015] The beneficial effects of adopting the above technical solution are: without consuming fuel, the thrust is generated by the continuous difference between the base (11), connecting rod (8), flywheel (2), outer frame (5), and inner frame (6), which enables the propulsion body (15) to propel the spacecraft to fly continuously in the universe.

[0023] The specific implementation of the precession difference engine will be described in detail below with reference to the accompanying drawings.
[0024] Figures 1, 2, 3, 4, and 5 illustrate the specific implementation method and process of the precession difference engine of the present invention:
[0025] Figures 1 and 2 show that the thruster body (15) contains multiple gyroscope compartments (1). Since the thrust generated by a single gyroscope compartment (1) and the center of gravity of the thruster body (15) are not on the same straight line, arranging multiple gyroscope compartments (1) is beneficial to increase thrust and maintain balance. By adjusting the direction and magnitude of the thrust of one or more gyroscope compartments (1), the thruster body (15) can be turned and its direction of motion can be changed.
[0026] Figures 3 and 2 show that the flywheel motor (7) drives the flywheel (2) to rotate at high speed, powered by the wire (14). The base drive motor (9) drives the connecting rod (8) and the flywheel (2) to rotate at high speed through the base (11). At this time, the flywheel (2) will cause the connecting rod (8) to deform and bend upward due to the precession of the gyroscope (Figure 3, arrow above the flywheel). The main motor (13) drives the outer frame (5) to rotate. At this time, the precession direction of the flywheel (2) on the left side of the base (11) in Figure 3 is the same as the rotation direction of the outer frame (5). The two forces with the same direction are superimposed on each other. The flywheel (2) on the right side of the base (11) is also affected. The advancing direction of wheel (2) is opposite to the rotation direction of outer frame (5). The two forces with opposite directions cancel each other out. When outer frame (5) drives base (11) and flywheel (2) to rotate, flywheel (2) on the right side of base (11) requires more force than flywheel (2) on the left side of base (11). As a result, the reaction force obtained on the right side of base (11) is greater than the reaction force obtained on the left side of base (11). The two reaction forces with opposite directions cancel each other out and generate a new resultant force. The direction of the resultant force is the direction of the thrust. Finally, a new thrust is generated, which drives the propeller body (15) to accelerate.
[0027] In Figures 3, 2 and 5, the outer frame (5) and the inner frame (6) rotate at the same speed. When the outer frame (5) drives the base (11) and the flywheel (2) to rotate 180 degrees, the direction of the flywheel (2) in Figure 3 should change to downward. However, since the outer frame (5) and the inner frame (6) rotate at the same speed, the inner frame (6) also drives the base (11) and the flywheel (2) to rotate 180 degrees. The direction of the flywheel (2) is still upward. Therefore, the outer frame (5) and the inner frame (6) will generate two thrusts for each rotation (Figure 5). When the inner frame (6) drives the base (11) and flywheel (2) to rotate, it will change the direction of the flywheel (2)'s advance, and also change the magnitude of the resultant force of the flywheel (2) on the right side of the base (11) and the flywheel (2) on the left side of the base (11) and the rotation of the outer frame (5), thereby changing the magnitude of the thrust. Therefore, the direction of the two thrusts generated by the outer frame (5) and the inner frame (6) for each rotation is not fixed, and the magnitude of the thrust is not fixed either. When there is only one gyroscope cabin (1), the thrust generated will cause the base (11) to advance in an arc twice (left side of Figure 5). When there are multiple gyroscope cabins (1) arranged symmetrically, the thrust generated will cause the base (11) to advance in a straight line twice (right side of Figure 5).
[0028] In Figure 4, the base (11) drives the connecting rod (8) and the flywheel (2) to rotate at high speed (the white arrow pointing horizontally to the left in Figure 4), causing the flywheel (2) on the right side and the flywheel (2) on the left side of the base (11) to move upward simultaneously (the white arrow pointing vertically upward in Figure 4). At this time, the rotation direction of the outer frame (5) (the gray arrow in Figure 4) is the same as the forward direction of the flywheel (2) on the left side. The two forces with the same direction are superimposed on each other. The rotation direction of the outer frame (5) (the gray arrow in Figure 4) is opposite to the forward direction of the flywheel (2) on the right side. The two forces with opposite directions cancel each other out. Therefore, the force required for the outer frame (5) to drive the flywheel (2) on the left and right sides of the base (11) to rotate is different in magnitude.
[0029] The process and conclusion of this invention are as follows: Powered by wire (14), the flywheel motor (7) drives the flywheel (2) to rotate at high speed. The base drive motor (9) drives the connecting rod (8) and the flywheel (2) to rotate at high speed through the base (11). Due to the precession of the gyroscope, the flywheel (2) will cause the connecting rod (8) to deform and bend upward. Then the main motor (13) drives the outer frame (5) to rotate. At this time, the precession direction of the flywheel (2) on the left side of the base (11) in Figure 3 is the same as the rotation direction of the outer frame (5). The two with the same direction are... The forces superimpose each other. The direction of advance of the flywheel (2) on the right side of the base (11) is opposite to the direction of rotation of the outer frame (5). The two forces with opposite directions cancel each other out. The flywheel (2) on the right side of the base (11) requires more force than the flywheel (2) on the left side of the base (11). As a result, the reaction force obtained by the right side of the base (11) is greater than the reaction force obtained by the left side of the base (11). The two reaction forces with opposite directions cancel each other out and generate a new resultant force. The direction of the resultant force is the direction of the thrust, and finally a new thrust is generated. The outer frame (5) and the inner frame (6) rotate at the same speed. When the outer frame (5) drives the base (11) and the flywheel (2) to rotate 180 degrees, the direction of the flywheel (2) in Figure 3 should change to downward. However, because the outer frame (5) and the inner frame (6) rotate at the same speed, the inner frame (6) also drives the base (11) and the flywheel (2) to rotate 180 degrees. The direction of the flywheel (2) is still upward. Therefore, the outer frame (5) and the inner frame (6) will generate two thrusts every time they rotate, thereby using the propulsion body (15) to propel the spacecraft to fly continuously in the universe.
[0030] When it is necessary to adjust the flight direction and turning of the spacecraft, adjusting the direction and magnitude of the thrust of one or more gyroscope modules (1) can enable the propulsion body (15) to turn and change its direction of motion.
[0031] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
