我国高原地区地域辽阔,地势起伏不平,有很多区域依靠陆地交通难以到达勘察,而直升机的飞行特点可以弥补其不足。无人直升机在高原地区的广泛使用,对推动高原地区的国防建设、反恐等具有重要作用。然而,高原地区的特殊环境也会给直升机设计造成困难。本文主要就无人直升机在高原环境下的起降能力进行研究。 China’s plateau region has a vast territory with undulating topography. Many regions rely on land transportation to reach the survey site. The helicopter’s flight characteristics can make up for the deficiencies. The widespread use of unmanned helicopters in the plateau region plays an important role in promoting national defense construction and anti-terrorism in the plateau region. However, special environments in the plateau can also create difficulties for helicopter design. In this paper, the research on the take-off and landing abilities of unmanned helicopters in the plateau environment is mainly studied.
