HYDRODYNAMICS ANALYSIS OF MARINE AMPHIBIOUS AIRCRAFT L8 HULL BY FLUENT SOFTWARE

Nowadays, design and manufacturing of amphibious aircrafts known as a flying boat are embraced in the maritime transport industries, military usage and relay. Although such flying vessels have been arranged in the new technologies of marine industries but the researchers and designers are able to become the owners of design-engineering science of amphibious marine vessels in the shortest, possible time. In view of prevailing equations on computational fluids and hydrodynamic of air-sea amphibious aircraft movement, this paper analyzed a sample of these vessels species with 4°, 6°, 8° angles of attack of the underside of the aircraft airfoil and action of two types, laminar and turbulent Reynolds flow was taken. The results showed that the lift and drag coefficients in two laminar and turbulent conditions were proportional to the dynamic stability and consistent with experimental design and manufacturing and represented the stability of the flying vessel in two laminar and turbulent flow.
