概述了微型飞行器研究与发展现状,分析了实用化面临的主要技术关键,重点讨论了低雷诺数空气动力学、高升阻比气动布局、智能控制等问题.已有的经验和理论分析表明:主尺度小于15cm以后,用常规方法已经很难设计出具有良好飞行性能的微型飞行器,而必须采用仿生学方法.对微型飞行器仿生学设计中的一些主要问题,包括高升力、高机动性、抗干扰稳定性以及飞行过程的力能学分析等问题分别进行了讨论.
The current status of the research and development of the micro-aircraft is summarized, and the key technical issues facing the practicalization are analyzed. The problems of low Reynolds number aerodynamics, ascending aerodynamic resistance and aerodynamic layout, intelligent control, etc. are discussed emphatically. The existing experience and theoretical analysis show that: After the scale is less than 15cm, it has been difficult to design a micro-aircraft with good flight performance by conventional methods, and the bionics method must be adopted. Some major problems in the design of micro-aircraft bionics include high lift, high maneuverability, Stability and flight force analysis of energy and other issues were discussed.
