Seaplanes are essential for transportation in countries like Indonesia, given its archipelagic nature. These types of aircraft can land on both water and conventional runways, perfectly suited for Indonesia's geography. The floaters, a key component of seaplanes, significantly influence performance during take-off and landing, necessitating precise hydrodynamic design. While studies have focused on reducing resistance forces and ensuring water stability, there is still a gap in understanding how different floater shapes impact aerodynamic characteristics during cruise flight, which is crucial for fuel efficiency and cost-effectiveness. This research examines how various float shapes affect aircraft aerodynamics, particularly lift and drag coefficients. Numerical simulations with different buoy models and angles are conducted to gauge the impact. Grid independence testing demonstrates that denser mesh resolution stabilizes coefficients, yielding reliable simulation data. Results show varying performance among float shapes, with type 4 floaters exhibiting higher lift coefficients or lower drag forces, thus affecting fuel efficiency. Visualization of pressure distribution on different buoy shapes at varying wind angles reveals differences in aerodynamic characteristics based on buoy design. These findings enhance understanding of float shape's aerodynamic influence, particularly during cruising flight, offering insights to optimize seaplanes for improved fuel efficiency and reduced operational costs.
