水陆两栖飞机水动强度技术的现状与发展

Review on Strength Technology of Amphibious Aircraft Induced by Hydrodynamics

与陆基飞机和直升机相比,水陆两栖飞机有其独特优势,应用前景广泛。设计时为了确保水陆两栖飞机在水上环境的正常使用,必须按照飞机在水面运动过程中的水动载荷进行充分的结构强度设计,确保飞机在水动载荷作用下的结构完整性。本文主要围绕水陆两栖飞机的研制需要,阐述了国内外在飞机水动载荷设计与验证方面的研究现状与技术进展,并介绍了在国家大型水陆两栖飞机研制过程中开展的楔形体模型仿真、波浪模型仿真、水面效应仿真、全机模型仿真以及缩比模型试验等方面的研究工作,探讨了后续水陆两栖飞机在水动弹性设计方面的发展趋势。

Compared with land aircraft and helicopter, amphibious aircraft has its unique advantages and wide application prospects. During the design, in order to ensure the normal use of amphibious aircraft under the water environment, it is necessary to carry out sufficient structural strength design according to the hydrodynamic load induced by the water movement so as to ensure the integrity of the structure. This paper mainly focuses on the development demand of amphibious aircraft, the research status and technical progress on the design and validation of aircraft hydrodynamic load at home and abroad. The researches of wedge model simulation, wave model simulation, water surface effect simulation, whole aircraft model simulation and scaled model test in the development of Chinese large amphibious aircraft are introduced, and the development trend of hydroelastic design for amphibious aircraft is also discussed.
