摘要: 文章主要介紹了紅外加熱籠在結(jié)構(gòu)設(shè)計(jì)中如何防止加熱帶熱變形問題，闡述了加熱帶噴涂黑漆過程采用的防污染工藝以及為了防止相鄰加熱區(qū)間熱流相互干擾所采取的措施。試驗(yàn)證明其工藝設(shè)計(jì)效果明顯，這些工藝措施的實(shí)行，不僅提高了外熱流模擬的精度和可靠性，而且保證了型號(hào)試驗(yàn)的順利完成。Abstract: The paper discusses how to prevent deformation of heating tapes by appropriate design. An anti-pollution technology is adopted during spraying black paint on the tape, and some measures are taken to prevent the thermal flow in the adjacent heating zone from causing interference. The test results show that these methods and measures not only increase the accuracy and reliability of thermal flow simulation but also ensure the success of intended experiments for spacecraft.
