Description

Eccentric momentum thruster TECHNICAL FIELD

[0001] The present application relates to the technical field of space propulsion, in particular to an eccentric momentum thruster. BACKGROUND

[0002] Rocket engines need to consume fuel, and the limited fuel of a rocket in space will run out one day. A robot called cubli cube can stand up by using the reaction force of a momentum wheel, because the momentum wheel gives the shell an upward reaction force. By replacing the shell with a U-shaped link and adjusting the position of the acceleration and deceleration stages of the momentum wheel, the size difference of the displacement distance of the object can be generated by combining the eccentric wheel, so that the spacecraft can continue to fly in space without fuel.

[0003] SUMMARY

[0004] The technical problem to be solved by the present application is to provide an eccentric momentum thruster, which uses a combination of a U-shaped link, a motor generator and a momentum wheel inside the thruster body to function as an eccentric wheel, so that the thruster body can move up and down, and the motor generator can accelerate and decelerate the momentum wheel. The reaction force generated by the acceleration and deceleration of the momentum wheel can cause the thruster body to move up and down with a size difference in displacement distance, so that the thruster body can push the spacecraft to continue to fly in space.

[0005] To achieve the above purpose, the present application provides the following technical scheme:

[0006] The eccentric momentum thruster comprises a thruster body (1) which is static in a vacuum weightless state, two circular cavities (2) are arranged inside the thruster body (1), the circular cavities (2) are divided into an acceleration stage (7) and a deceleration stage (8), a U-shaped link (3) is arranged inside the circular cavities (2), a motor generator (4) is arranged at the end of the U-shaped link (3), a momentum wheel (5) is arranged outside the motor generator (4), the momentum wheel (5) is a flywheel made of a material with high density, a ring of position sensors (9) is arranged on the inner wall of the circular cavities (2), a main motor (6) is arranged at the rear of the thruster body (1), a conductive slip ring (10) is arranged on the output shaft of the main motor (6), the output shaft of the main motor (6) is connected with the U-shaped link (3), and wires (11) are connected to the motor generator (4) through the conductive slip ring (10) to provide power supply and transmission control signals.

[0007] In order to eliminate air resistance and offset torque, the circular cavities (2) are in a vacuum state, and the U-shaped links (3) in the two circular cavities (2) rotate in opposite directions.

[0008] In order to facilitate the propeller body (1) in the acceleration stage (7) to move up a large distance, the reaction force generated by the motor generator (4) and the momentum wheel (5) in the acceleration stage (7) moves the U-shaped connecting rod (3) upward, and the direction of the reaction force is opposite to the direction of the movement of the U-shaped connecting rod (3), at this time, when the U-shaped connecting rod (3) moves from top to bottom, a large force is needed to overcome the reaction force generated by the motor generator (4) and the momentum wheel (5) in the acceleration stage (7), thereby generating a large upward reaction force on the propeller body (1).

[0009] In order to facilitate the propeller body (1) in the deceleration stage (8) to move down a small distance, the motor generator (4) decelerates the momentum wheel (5) in the deceleration stage (8), and the reaction force generated by the deceleration of the momentum wheel (5) moves the U-shaped connecting rod (3) upward, and the direction of the reaction force is the same as the direction of the movement of the U-shaped connecting rod (3), at this time, when the U-shaped connecting rod (3) moves from bottom to top, only a small force is needed, thereby generating a small downward reaction force on the propeller body (1).

[0010] In order to change the moving direction and steering of the propeller body (1), the positions of the acceleration stage (7) and the deceleration stage (8) can determine the direction of the displacement of the propeller body (1), changing the position of the acceleration stage (7) and the deceleration stage (8) in one of the two circular cavities (2) can make the propeller body (1) steer, and changing the position of the acceleration stage (7) and the deceleration stage (8) in both of the two circular cavities (2) can make the propeller body (1) change the moving direction.

[0011] In order to make the propeller body (1) generate displacement, the combination of the U-shaped connecting rod (3), the motor generator (4) and the momentum wheel (5) functions as an eccentric wheel.

[0012] In order to move the U-shaped connecting rod (3) upward, the motor generator (4) and the momentum wheel (5) accelerate or decelerate the rotation speed of the momentum wheel (5) through the motor generator (4) according to the different rotation directions.

[0013] The beneficial effects of the above technical scheme are that the present application provides another method and idea different from the rocket engine, the combination of the U-shaped connecting rod, the motor generator and the momentum wheel inside the propeller body functions as an eccentric wheel, the propeller body moves up and down, and the motor generator accelerates and decelerates the momentum wheel, the reaction force generated by the acceleration and deceleration of the momentum wheel makes the distance of the upward and downward displacement of the propeller body different in size, so that the propeller body can continuously fly in the universe by pushing the spacecraft.

[0020] The specific embodiments of the eccentric momentum propeller will be described in detail below with reference to the accompanying drawings.

[0021] Figures 1, 2, 3, and 4 show the specific embodiments and processes of the eccentric momentum propeller of the present application:

[0022] Figure 1, there is a robot called cubli cube, which is a cube with a momentum wheel driven by a motor inside, which can make the cubli cube stand up from the flat state (dashed box) by the reaction force of the momentum wheel. According to the different rotation directions of the momentum wheel, it can be made to stand up to the left or to the right by acceleration or deceleration.

[0023] Figures 2 and 3, the propeller body (1) has two circular cavities (2) inside, the main motor (6) drives the motor-generator (4) and the momentum wheel (5) to rotate, while causing the propeller body (1) to move up and down.

[0024] Figure 4, the U-shaped link (3) is substituted for the cubli cube robot shell, in the acceleration stage (7), the reaction force generated by the motor generator (4) and the momentum wheel (5) accelerating rotation makes the U-shaped link (3) move upward, the direction of the reaction force is opposite to the direction of the U-shaped link (3) movement, at this time, when the U-shaped link (3) moves from top to bottom, a large force is needed to overcome the reaction force generated by the motor generator (4) and the momentum wheel (5) accelerating rotation, thereby generating a large upward reaction force on the propeller body (1), making the propeller body (1) displace a large distance upward in the acceleration stage (7). In the deceleration stage (8), the motor generator (4) decelerates the momentum wheel (5), converting the kinetic energy of the momentum wheel (5) into electrical energy, at the same time, the reaction force generated by the momentum wheel (5) deceleration makes the U-shaped link (3) move upward, the direction of the reaction force is the same as the direction of the U-shaped link (3) movement, at this time, when the U-shaped link (3) moves from bottom to top, only a small force is needed, thereby generating a small downward reaction force on the propeller body (1), making the propeller body (1) displace a small distance downward in the deceleration stage (8).

[0025] The process and conclusion of the present application, the two main motors (6) of the propeller body (1) drive the U-shaped link (3) in the two circular cavities (2) to rotate in opposite directions, according to the signal of the position sensor (9), when the U-shaped link (3) enters the acceleration stage (7), the reaction force generated by the motor generator (4) and the momentum wheel (5) accelerating rotation makes the U-shaped link (3) move upward, the direction of the reaction force is opposite to the direction of the U-shaped link (3) movement, at this time, when the U-shaped link (3) moves from top to bottom, a large force is needed to overcome the reaction force generated by the motor generator (4) and the momentum wheel (5) accelerating rotation, thereby generating a large upward reaction force on the propeller body (1), making the propeller body (1) displace a large distance upward in the acceleration stage (7). According to the signal of the position sensor (9), when the U-shaped link (3) enters the deceleration stage (8), the motor generator (4) decelerates the momentum wheel (5), converting the kinetic energy of the momentum wheel (5) into electrical energy, at the same time, the reaction force generated by the momentum wheel (5) deceleration makes the U-shaped link (3) move upward, the direction of the reaction force is the same as the direction of the U-shaped link (3) movement, at this time, when the U-shaped link (3) moves from bottom to top, only a small force is needed, thereby generating a small downward reaction force on the propeller body (1), making the propeller body (1) displace a small distance downward in the deceleration stage (8). Combined with Figure 2, Figure 3, and Figure 4, the distance of the upward displacement of the propeller body (1) is greater than the distance of the downward displacement, making the propeller body (1) move upward.

[0026] When it is necessary to adjust the moving direction and steering of the propeller body (1), in combination with Fig. 2 and Fig. 4, the positions of the acceleration stage (7) and the deceleration stage (8) in one of the circular cavities (2) are changed to make the propeller body (1) steer, and the positions of the acceleration stage (7) and the deceleration stage (8) in both of the circular cavities (2) are changed to make the propeller body (1) change the moving direction.

[0027] The above merely is the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which all belong to the protection scope of the present application.
