Ultra-low orbit satellite with aerodynamic heating protection function

Abstract

The invention provides an ultra-low orbit satellite with an aerodynamic heating protection function. The ultra-low orbit satellite comprises a satellite body. The satellite body comprises a satellite head, a satellite bottom plate and a satellite side surface structure plate. The satellite side surface structure plate is divided into a satellite conical segment and a satellite columnar segment. The ultra-low orbit satellite further comprises a heat insulation gasket, aerogel, a first heat insulation layer and a second heat insulation layer, wherein the heat insulation gasket is arranged in the satellite body and located between the satellite head and the satellite conical segment; the aerogel is located on the outer surface of the satellite head and the outer surface of the satellite conical segment; the first heat insulation layer is located on the outer surface of the aerogel and the outer surface of the satellite columnar segment; and the second heat insulation layer is located in the satellite body and covers the inner side of the satellite head and the inner side of the satellite side surface structure plate. According to the ultra-low orbit satellite with the aerodynamic heating protection function, the problem that the satellite head and the side edge are high in temperature due to aerodynamic heating when the satellite operates on a low orbit at a high speed is effectively solved, a single machine in the satellite can work within an appropriate temperature range, and the heat protection problem of the satellite operating in an ultra-low orbit region for a long time in the aerospace field is solved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an ultra-low orbit satellite with aerodynamic heating protection. Background technique [0002] In the field of aerospace, all kinds of aircraft fly in various areas from the ground to deep space. At present, there is no detailed division standard for each area in the world. It is generally considered that the space area below 20km above sea level is the aviation area. , the area between 20km and 100km is the adjacent space area, and the space area above 100km is the aerospace area. In addition, the aircraft that reach the altitude above the atmosphere (that is, above 100km) but cannot complete the orbital flight due to insufficient speed are called "suborbital aircraft". space tourism. [0003] Due to their very low altitude, near-space vehicles and sub-orbital vehicles have outstanding advantages such as high detection accuracy and strong penetration capabilities, but it i...
