New thermal control technology for jovian mission
摘要
Abstract
Usually the Jovian probe uses Venus-Earth-Earth gravity-assist mission sequences to achieve Earth-Jupiter transfer.due to a wide range of changes in the daily distance caused by large-scale changes in solar light intensity,which in turn leads to the drastic temperature variation of the probe's external thermal control components,which not only needs to adapt to the high solar heat flow of up to about 2,938W/m2 near Venus,but also needs to adapt to the low solar heat flow of 50 W/m2 near Jupiter,which poses a challenge to the extreme high and low temperature adaptability of the thermal control design.Currently,the traditional approach mainly adopts thermal control measures such as fluid loops,shutters and multi-layer components to control temperature,which increases the complexity and design difficulty of the thermal control system.In this paper,we proposed a new type of thermal control design method We used a three-dimensional heat-insulating solar panel to orbstruct the sunlight,and adopted a closed-loop decoupling control algorithm to regulate the positional relationship between the solar wing and the star body.By deminishing the solar thermal radiation to the detector's external surface of the stand-alone device and maintaining a fixed heat-sinking surface,the temperature fluctuation of the detector is reduced.Through simulation analysis,it has been shown that when the solar panel is positioned 1.5 meters away from the star body,the heat dissipation capacity at the shaded area can reach 170W/m2,suitable for blocking high solar heat flux near Venus.When the solar panel is positioned 0.5 meters away from the star body,the heat dissipation capacity decreases to 50 W/m2,providing insulation and reducing heat loss at the heat-sinking surface near Jupiter.Our design has the advantages of simple thermal control design and high adaptability,and provides a new idea for the thermal control design of the subsequent deep space detectors.关键词
