【摘要】 在航空强国建设稳步推进的背景下，航空工程科技涉及专业领域多、技术风险高、资金投入大、发展周期长，需要制定长期、稳定的发展战略，才能集中力量突破航空工程科技的关键核心技术，实现航空工业的可持续发展。本文从民用飞机、航空动力、机载系统、空管系统4个方面出发，总结了世界航空工程科技发展态势，梳理了我国航空工程科技发展现状；识别出基础研究及技术储备、系统集成与产品体系研究、航空动力技术、机载系统研发及试验、航空维修能力、工业软件及基础元器件等方面的不足。在此基础上，论证提出了未来20年我国航空工程科技发展构想，着重阐述了超声速客机、高速旋翼机、新能源飞机、混合电推进系统、新一代空管技术、智能化客机技术、全复合材料航空发动机技术、复合材料智能修复技术等未来项目部署的重点方向。研究建议，将航空强国建设列入国家中长期战略规划，强化科技创新体系建设，加强跨领域协作，注重国际合作，精准支撑未来20年航空工程科技发展。更多还原

【Abstract】 Aeronautical engineering science and technologies involve multiple disciplines, high technical risks, large capital investment, and long development cycles; therefore, a long-term, stable development strategy is needed to achieve breakthroughs regarding the key core technologies of aeronautical engineering science and technologies and to realize the sustainable development of the aeronautical industry. This study summarizes the global development trend and China’s development status of aeronautical engineering science and technologies from four aspects: civil aircraft, aero engine, airborne system, and air traffic control system. It also identifies the development deficiencies in terms of basic research and technical reserves; system integration and product system research; aero engine technology; airborne system research, development, and testing; aeronautical maintenance capabilities; and industrial software and basic components. On this basis, a 20-year development vision for aeronautical engineering science and technologies in China is proposed, as well as key directions for future project deployment: supersonic passenger aircraft, high-speed rotorcraft, new energy aircraft, hybrid electric propulsion systems, next-generation air traffic control technologies, intelligent passenger aircraft, all-composite aero engines, and intelligent repair technologies for composite materials. Furthermore, the study suggests incorporating aeronautical power construction into national medium-and long-term strategic planning, strengthening the construction of a scientific and technological innovation system, enhancing interdisciplinary cooperation, and emphasizing international collaboration, thereby precisely supporting the development of aeronautical engineering science and technologies in the next 20 years..更多还原
