【摘要】:空間太陽(yáng)望遠(yuǎn)鏡在軌運(yùn)行中,會(huì)受到復(fù)雜的空間環(huán)境影響,光學(xué)窗口的溫度變化將會(huì)直接影響后面光學(xué)系統(tǒng)成像質(zhì)量.熱設(shè)計(jì)的目的就是為了保證光學(xué)窗口的各部分保持在各自正常溫度范圍內(nèi),更重要的是能夠使望遠(yuǎn)鏡在地影結(jié)束后迅速進(jìn)入到工作狀態(tài),完成整個(gè)周期運(yùn)行.為了得到窗口在空間熱載荷下整個(gè)周期內(nèi)的溫度分布和變化趨勢(shì),需要對(duì)窗口穩(wěn)態(tài)及地影狀態(tài)中有無加熱兩種瞬態(tài)進(jìn)行仿真分析.通過對(duì)比兩種瞬態(tài)溫度分布的仿真結(jié)果,對(duì)窗口采取相應(yīng)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.
