运载火箭能实现高频率、低成本、"航班化"往返太空吗？西北工业大学科技成果转化企业——陕西 天回航天技术有限公司，用自主研发的"红龙二号"发动机给出了肯定答案。 天回航天董事长、西北工业大学教授刘红军介绍，这款150吨级混合循环液氧甲烷发动机，创新采 用在线智能检测与航班化可重复使用设计，预计重复使用次数不少于50次，这意味着未来真正迈向太空 运输的"航班时代"。 天回航天的技术突破，正是陕西推动科技创新和产业创新深度融合的生动体现。在科技成果转 化"三项改革"等一系列政策的推动下，陕西有很多像刘红军这样的科研人员，带着科技成果走向市场， 实现技术价值与市场需求的精准对接，为培育新质生产力、实现高水平科技自立自强注入强劲动能。 改革破冰，为高效转化"护航" "过去，我们手里握着技术专利，却因为'不敢转、不愿转、缺钱转'，只能让成果'躺'在实验室 里。"11月30日，陕西科技大学教授牛育华回忆起曾经的困境，感慨万千。 这样的困境，在陕西高校和科研院所中并不少见。陕西高校、科研机构众多，但长期以来，不少科 研人员手握专利技术，却被转化难题挡在市场大门外。 2022年，陕西以体制机制改革为突破口，在全省高校院所开展职 ...
