Abstract: After a hundred years of development, the amphibian aircraft becomes the rare type in the aircraft family. However, in modern aviation industry, its existence and significance should hardly be ignored. Its unique characteristics of take-off and landing on water/land make it capable of serving in multiple fields of civil and military areas. In addition to the conventional design and manufacturing technology of land-based aircraft, the unique key technology of amphibian aircraft is adopted to ensure her excellent take-off and landing characteristics on water, marking the significant development in aviation technology. Amphibian aircraft design features and technical characteristics, together with her development are analyzed from the aspects of traditional layout and innovative layout. Key technologies that affect its development are analyzed in the aspects of amphibian aircraft hydrodynamic and aerodynamic characteristics. The industrial application prospects of amphibian aircraft and the direction of technological development are discussed in the paper.
