More Electric Aircraft (MEA) is the development trend of future aircraft. With the development of electric technology and electrical actuation components, landing gear system leads to more electrical. The application of more technology in landing gear system and the related research work at home and abroad werre introduced. At last, some viewpoints about the development of more electric technology in landing gear system were proposed.%多电飞机是未来飞机的发展方向，随着飞机电力技术和电力作动部件的发展，起落架系统也逐步朝着多电作动的方向发展。本文介绍了多电技术在现役飞机起落架系统中的应用情况，以及国内外开展的相关研究工作，最后对起落架多电技术的发展提出了几点看法。
