Fractal structure on satellite surface

Abstract

The invention discloses a fractal structure on a satellite surface. A satellite body is a cube structure, and Sierpinski carpet patterns are created on any surface of the satellite body. The fractal structure comprises regular square pyramid protrusions taking squares in the middle of the Sierpinski carpet patterns as bottom surfaces.

Description

technical field [0001] The invention relates to the field of satellite thermal control, in particular to the satellite surface fractal structure. Background technique [0002] Microsatellites are currently one of the three research hotspots and development frontiers in the aerospace field, and are favored by the international aerospace community. The characteristics of small size, light weight, and high heat flux of microsatellites make the internal spaceborne equipment of microsatellites increasingly diverse and the working mode increasingly complicated; the uncertainty of the environment for performing space missions; and the reliability of microelectronic devices It is very sensitive to temperature, and the reliability will drop by 5% for every 1°C increase in device temperature at the level of 70-80°C. All of the above factors pose new challenges to the design of the microsatellite thermal control system. [0003] At present, the research on the thermal control system ...

AI Technical Summary

Problems solved by technology

In the current thermal control system of micro-satellites, the traditional research focus is mostly on the heat transfer system and the study of star surface materials, and it is often easy to ignore the influence of satellite surface morphology and structure on the star's heat transfer capability
