Problems solved by technology

[0002] The current satellites and deep space probes all use chemical fuel propellers, and they all carry a large amount of chemical propellants for acceleration and orbit change, which increases the cost of refueling propellants and increases the weight of satellites. The launch cost of the satellite is increased. In order to save chemical propellants, the aircraft cannot be continuously accelerated, the flight speed is slow, the interstellar flight time is long, and the fuel consumption is a little bit less. Therefore, it is necessary to carry as much propellant as possible to prolong its service life
Once the propellant is exhausted, it will cause the entire satellite to fail, shortening the service life of the satellite

Embodiment Construction

[0009] exist figure 1 The satellite is in the shape of a cuboid, and the all-electric thruster is installed inside the satellite, which is also a cuboid and consists of a linear slide (5). The components of the linear slide (5) are connected by a stepping motor (1). The shaft device (2), the shaft coupling (2) is connected with the screw rod (3), and the moving slider (6) is driven by the screw rod (3) to make a linear motion. There is an iron ball (4) on the moving slider (6) ), the end of the screw (3) close to the stepping motor (1) is called the near dead point, which is close to the tail of the satellite, and the end of the screw (3) farthest from the stepping motor (1) is called the far dead point, which is close to the head of the satellite department. When the moving slider (6) and the iron ball (4) are at the near dead point, the stepper motor (1) rotates in the forward direction, the speed changes from slow to fast, and the screw rod (3) is driven to rotate through ...

Abstract

The invention discloses a satellite all-electric propulsion system. Electric energy is used for propelling and accelerating an all-electric propeller. The built satellite is rectangular, the all-electric thruster is arranged in the satellite, is also rectangular and consists of a linear sliding table, the linear sliding table is formed by connecting a stepping motor with a coupler, connecting the coupler with a screw rod, driving a movable sliding block to do linear motion by the screw rod, and an iron ball is arranged on the movable sliding block. The end, close to the stepping motor, of the lead screw is called a near dead center and close to the tail of the satellite, and the end, farthest from the stepping motor, of the lead screw is called a far dead center and close to the head of the satellite. The stepping motor drives the movable sliding block and the iron ball, so that the iron ball generates inertia to accelerate the satellite, and the stepping motor can also drive the movable sliding block and the iron ball, so that the linear sliding table generates counter-acting force, generates forward thrust and accelerates the satellite, and the satellite is accelerated through the two methods.

Description

technical field [0001] The invention relates to a satellite thruster technology, in particular to a technology for propulsion and acceleration of satellites using electric energy. Background technique [0002] The current satellites and deep space probes all use chemical fuel propellers, and they all carry a large amount of chemical propellants for acceleration and orbit change, which increases the cost of refueling propellants and increases the weight of satellites. The launch cost of the satellite is increased. In order to save chemical propellants, the aircraft cannot be continuously accelerated, the flight speed is slow, the interstellar flight time is long, and the fuel consumption is a little bit less. Therefore, it is necessary to carry as much propellant as possible to prolong its service life. Once the propellant is exhausted, it will cause the entire satellite to fail, shortening the service life of the satellite. Contents of the invention [0003] In order to ...
