In this paper, based on the thermal problems in the optoelectronic system of SSPS via Orb-shape Membrane Energy Gathering Array (SSPS-OMEGA), a thermal management strategy of full-spectrum selective photonic thin-film based on the photoelectric characteristics of photovoltaic cells and pump-driven fluid flow loop is proposed with combination of passive and active cooling methods. Simulation results indicate that the full-spectrum selective thin film can significantly reduce the parasitic heat source in ultraviolet band and sub-band gap, from 205 to 72.8 W/m<sup>2</sup> and from 46 to 4.5 W/m<sup>2</sup>, respectively. Meanwhile, it can effectively increase the emissivity from 0.84 to 0.938. On the other hand, the pump-driven fluid flow loop is designed and the temperature of the PV cell array is well controlled below 50 ℃ for ground-based demonstration validation system of the SSPS-OMEGA project. Finally, a simple experiment investigation is carried out demonstrate the thermal control performance of pump-driven fluid flow loop for photoelectric system.</p></div>","PeriodicalId":100039,"journal":{"name":"Advances in Astronautics Science and Technology","volume":"5 1","pages":"19 - 29"},"PeriodicalIF":0.0,"publicationDate":"2022-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50043270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has the advantages of no propellant consumption, long lifetime, and high flexibility. Since the electromagnetic formation dynamics is nonlinear and strongly coupled, the magnetic dipole assignment is difficult. This paper studies the electromagnetic formation capability and dipole assignment of double satellites. The feasible engineering constraints are given based on the overall energy consumption optimization goal, which significantly simplifies the electromagnetic model and reserves a certain degree of freedom to assign electromagnetic dipoles. The relationship among electromagnetic force, torque, and dipole is illustrated by the diagram method. We also calculate the envelope of electromagnetic formation capability. The analytical solution of the dipole with the optimal energy consumption and the numerical solution of the dipole with the least angular momentum is given via the typical dipole assignment strategies. The results of the calculation example show that the approaches of dipole assignment are effective.</p></div>","PeriodicalId":100039,"journal":{"name":"Advances in Astronautics Science and Technology","volume":"4 2","pages":"143 - 156"},"PeriodicalIF":0.0,"publicationDate":"2021-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50523728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For validating space environment resistance of polyimide foam, outgassing in vacuum, thermal cycle, total dose radiation, thermal vacuum and atomic oxygen tests have been performed. The apparent core density of this foam is as low as 7.5 ± 0.5 kg m<sup>−3</sup>. Its volume percentage of open cells is over 98%, which is beneficial to outgas in orbit.

After severe space environment tests, thermal conductivity becomes even lower, compressive strength raises slightly, but shear property declines apparently.
