短距起飞/垂直降落飞机升力系统研究进展

Research Progress of Lift System for Short Take-Off/Vertical Landing Aircraft

短距起飞/垂直降落(STOVL)升力系统是一种允许飞机在极短跑道甚至无跑道条件下起降的航空技术,提供了飞行器在受限空间和复杂环境中实施起降操作的能力,对军用和民用领域都有重要意义。尽管国际上对STOVL飞机的研究已有历史,但敏感或专用技术的信息并未广泛共享。为深入探索STOVL飞机升力系统的关键技术、难点和发展方向,在全面分析和总结最新研究进展和技术挑战的基础上,针对该领域的研究进展进行综述,特别是针对F-35B飞机深入探讨了STOVL飞机升力系统的关键技术,包括升力风扇、三轴承矢量喷管和整机推进系统性能等。在此基础上总结归纳了国内外学者在复杂结构设计、动力系统建模、环境影响评估和性能优化等方面的研究,为STOVL飞机的研发与优化设计提供方向参考。

Short take-off/vertical landing(STOVL)system is an aviation technology that allows aircraft to take off and land on extremely short runways or even without runways,and it provides the ability for aircraft to operate taking off and landing in confined spaces and complex environments,which is of great significance in both military and civilian fields.Although there has been some international research on STOVL aircraft,the information on sensitive or proprietary technology has not been widely shared.To further explore the key technologies,difficulties,and development directions of STOVL aircraft lift systems,based on a comprehensive analysis and summary of the latest research progress and technical challenges,a review is conducted on the research progress in this field.Especially for F-35B,the key technologies of STOVL aircraft,such as lift fans,three-bearing vector nozzle,and overall propulsion system performance,etc.are discussed in depth.On this basis,research efforts at home and abroad on complex structural design,power system modeling,environmental impact assessment,and performance optimization are summarized,providing directional references for the development and optimization of STOVL aircraft.
