Deep space probe employing mass loss-free magnetic sail and optical sail combination for propulsion

Abstract

The invention provides a deep-space probe propelled by a combination of non-massive magneto-optic double sails, comprising: a probe body, a power supply device, a driving device, a magnetic sail deployment mechanism, a magnetic field generating device, a light sail, and a telescopic rod mechanism, The detector body is located between the magnetic sail and the light sail, and is connected by a mechanical connection device; the power supply device supplies power to the propulsion system, the magnetic sail deployment mechanism stretches and expands the magnetic sail, and the magnetic field generating device acts as a magnetic The main device of the sail, after electrification, the current generates a magnetic field and interacts with the solar wind plasma flow in space to generate thrust. The telescopic rod mechanism unfolds the light sail, and the light sail generates light pressure driving force under the irradiation of sunlight. This The deep space probe provided by the invention does not need to carry propellant, the thrust is sustainable, and it has incomparable advantages and broad application prospects of traditional chemical propulsion and electric propulsion.

Description

technical field [0001] The invention relates to a novel deep-space detector, in particular to a design of a deep-space detector that is propelled by a mass-lossless magneto-optical double-sail combination. Background technique [0002] Propulsion technology is the key technology in the design of deep space probes. The total speed increment required for planetary detection in the solar system reaches about 10km / s. At present, deep space probes mainly use chemical propulsion and electric propulsion technologies, and their highest specific impulses are 350s and 4000s respectively. , the specific impulse is low, requiring the detector to carry a large amount of fuel, respectively reaching 94.6% and 22.5% of the total mass of the detector, thereby reducing the ability of the detector to carry payloads and reducing the effectiveness of scientific output. [0003] In order to overcome the shortcomings of traditional propulsion methods, light sails and magnetic sails are novel and e...

AI Technical Summary

Problems solved by technology

The light sail uses solar radiation to generate pressure, and the sun’s photons hit the light sail continuously, making the momentum of the light sail gradually increase; the magnetic sail is the magnetic field generation device carried by the detector itself that interacts with the solar wind plasma flow to generate thrust, neither of which needs Any propellant, but gets less thrust
