【摘要】:空間太陽望遠鏡在軌運行中,會受到復雜的空間環(huán)境影響,光學窗口的溫度變化將會直接影響后面光學系統(tǒng)成像質量.熱設計的目的就是為了保證光學窗口的各部分保持在各自正常溫度范圍內,更重要的是能夠使望遠鏡在地影結束后迅速進入到工作狀態(tài),完成整個周期運行.為了得到窗口在空間熱載荷下整個周期內的溫度分布和變化趨勢,需要對窗口穩(wěn)態(tài)及地影狀態(tài)中有無加熱兩種瞬態(tài)進行仿真分析.通過對比兩種瞬態(tài)溫度分布的仿真結果,對窗口采取相應熱控措施,取得了較好的熱控效果.
[Abstract]:The space solar telescope will be affected by the complex space environment in orbit, and the temperature change of the optical window will directly affect the imaging quality of the optical system behind it. The purpose of thermal design is to ensure that all parts of the optical window remain within their normal temperature range. More importantly, the telescope can quickly enter the working state after the earth shadow is finished and complete the whole cycle operation. In order to obtain the temperature distribution and variation trend of the window in the whole period under the space thermal load, it is necessary to simulate and analyze whether there are two transient states in the steady state and the shadow state of the window. By comparing the simulation results of two kinds of transient temperature distribution, the corresponding thermal control measures are taken for the window, and good thermal control effect is obtained.
