Karakteristik aerodinamika flying boat pada ketinggian ground effect (Studi kasis model remote control flying boat pada ketinggian 0,2 dan 1m: The aerodynamic characteristics of a flying boat on the ground effect altitude (Case study: a flying boat remote control model at 0,2 m and 1 m altitute)

The paper presents an analysis of the flight performance and stability and control of a Flying Boat remote control model on the ground effect altitude. It begins with a three dimensional measurement of a Flying Boat remote control model by using a laser tracking photo camera and a drawing software. The 3 D model was drawn by solid drawing on the CATIA software. The 3 D model was analyzed by using computational fluid dynamics CFx AnSys due to the rectangular wing with dihedral configuration with NACA 23012 airfoil. The maximum takeoff weight is around 25.0 kg powered with a single engine propeller, 5.5 HP. The surface effect phenomena of the Flying Boat remote control model was simulated by using CFx Computational Fluid Dynamics software, AnSys with the airspeed, V = 35.0 knots and shows a good results at the altitude of 20.0 cm. The longitudinal static stability analysis provides a good result at 1.0 meter altitude. Simulations were performed to the PUNA “Alap alap” flight performance test during cruise at 7800 feet as data verification. The adaptive ground effect control system is solved by transfer function equation matrix.
