FT300水陆两用型三座轻型飞机双浮筒配置的探讨

Research on Disposition of the Floats of FT300 3 Seat Light Amphibian

简要介绍了FT300水陆两用三座轻型飞机型号设计过程中水动方面的研究与分析，重点对三座轻型飞机浮筒线性选择、双浮筒相对鸭式飞机安装位置的配置以及轻型水上飞机的主要水动特性的理论分析作了研究，建立了鸭式布局飞机重心相对浮筒断阶位置的新值。

The analysis of water dynamics in the type design process of FT300 3 seat light amphibian is introduced. The contour choice of the floats,the location to fix of the floats to the canard aircraft, the theoretic analysis of the main water dynamic characteristics for light seaplane are emphasized,and the new parameter of the centre of gravity of canard configuration airplane to the floats breaking steps is presented.
