材料与结构制造技术水平是航空技术得以发展的前提条件，因此各航空业先进国家都在为２１世纪航空技术的发展而大力开发航空制造技术。本文根据目前航空制造技术开发取得的进展，展望了２１世纪航空制造技术的主要内容和特点；并指出，到２１世纪，制造技术的进展将把航空技术推入高超音速跨大气层飞行时代。
The level of materials and structural manufacturing technology is the prerequisite for the development of aviation technology. Therefore, all the advanced countries in the aviation industry are making great efforts to develop aviation manufacturing technology for the development of aviation technology in the 21st century. Based on the progress made in the development of aeronautical manufacturing technology, the paper forecasts the main contents and features of aeronautical manufacturing technology in the 21st century. It points out that by the 21st century, advances in manufacturing technology will push aviation technology into the hypersonic and trans-atmospheric flight.
