With the advancement of technology, aerospace science and design of aircrafts have entered a new phase. Obviously, in order to improve this industry, it is necessary to use up-to-date engineering technologies, but the main issue is the high cost and time that are being spent on three-dimensional calculations in the aerodynamics analysis and design. By evaluating the results of two-dimensional analysis in numerical method for an amphibious aircraft”ICONA۵”, with the help of Digital DATCOM in this article, it has been tried to approve ۲-D numerical method. After evaluation of ۲-D numerical method, the hydrodynamic calculations of the amphibious aircraft is done via ۲-D numerical method. So the main concern is showing that this method is faster, less expensive and also accredited for the initial stages of hydro-aerodynamic design.
