This paper analyzes the effects of a hydrofoil in takeoff performance improvements of an amphibious aircraft. The physical framework incorporates hydrodynamic effects such as lift, drag and cavitation effects from the hydrofoil, computed using highfidelity cavitation and turbulence models in ANSYS Fluent along with a preliminary 2D analysis. The takeoff performance is analyzed using an in-house code developed in Python, using the Froude resistance drag model and preliminary thrust estimation from a conceptual design based on historical data. Stability is considered by calculation of required trimming forces from the empennage during the takeoff run.
