1月19日上午，神舟二十号飞船返回舱在东风着陆场成功着陆，带回一套"飞天战衣"。这位中国航天员 的"老战友"——舱外服B，是我国空间站首套实现"4年20次"目标的舱外航天服。在这套"飞天战衣"中， 一些关键部件是"河南制造"的智慧结晶。 面窗组件是航天员在外太空活动时观察外界的窗口，被形容为航天员的"眼睛"。神舟二十号飞船返回舱 此次带回的"飞天战衣"，使用的就是郑州大学研制的新一代航天面窗。 郑州大学橡塑模具国家工程研究中心执行主任刘春太介绍，航天面窗需在极高温和极低温的极端环境下 保持性能稳定。为了破解这一难题，该中心开展了包括计算机科学、材料科学、力学在内的多学科研 究，研制出的新一代面窗主要有四层结构：两层为压力面窗，中间充氮，起到隔热和防结雾的作用；外 层为可更换防护面窗；最外层为滤光面窗，航天员可根据自身位于阳照区和阴影区位置来打开或者放 下，防止光线射入眼睛。 此项技术和产品，已多次应用在"神舟"载人飞船发射任务中，并获得国家专利。自2021年5月29日随"天 舟二号"货运飞船飞行以来，在8次载人飞行任务中接力使用，并由原设计指标的15次实现了"4年20 次"延寿目标。（记者 尹江勇 樊雪婧） ...
