【摘要】：高溫合金前緣熱防護(hù)結(jié)構(gòu)由高溫合金蜂窩和隔熱氈、連接件構(gòu)成,同時具有承載和隔熱作用,易于拆卸和維修,具有經(jīng)濟(jì)性和安全性。通過分析高溫合金前緣熱防護(hù)結(jié)構(gòu)隔熱性能和承載能力,對前緣結(jié)構(gòu)進(jìn)行設(shè)計(jì)。高溫合金蜂窩隔熱效果良好,并可以承受1 200℃高溫。隔熱氈所用的隔熱材料在高溫試驗(yàn)下保持良好的隔熱效果,驗(yàn)證了本文傳熱分析方法的正確性。建立了傳熱迭代分析算例,確認(rèn)結(jié)構(gòu)各項(xiàng)參數(shù)滿足某型高速臨近空間飛行器的熱環(huán)境和承載使用要求,完成了前緣結(jié)構(gòu)隔熱一體化初步設(shè)計(jì)。
[Abstract]:The thermal protection structure of the front edge of the superalloy is composed of the honeycomb and the insulating felt of the superalloy, and the connectors have the functions of bearing and insulation, easy to disassemble and maintain, and economical and safe. By analyzing the thermal insulation property and bearing capacity of the thermal protective structure on the front edge of the superalloy, the design of the leading edge structure is carried out. High temperature alloy honeycomb insulation effect is good, and can withstand 1 200 鈩，
