Abstract

The use of Flying Inflatable Boat (FIB) vehicles has caught the attention in applications like search and rescue operations, military surveillance, and recreational activities. The aerodynamics of flat wings of FIB needs to investigate so that the performance, safety and efficiency vehicles can be improved. Changes in angle of attack, velocity, and air density affect lift and drag coefficients are evaluated using Computational Fluid Dynamics (CFD) analysis. Results show that the lift coefficient increases until an angle of attack of 34° meanwhile the ratio of CL/CD is increased up to angle of 5°. However, as the angle of attack (AOA) continues to increase the drag coefficient also rises. It is also found that both the lift coefficient and CL/CD ratio increase as the velocity goes up. Additionally, decrease of lift coefficient and CL/CD ratio accompanied by an increase in drag coefficient is observed as air density decreases
