Ground effect, is an inhanced lift that is applied to the wings of wigcrafts, in close to the
surface of earth or sea. wigcrafts, the vessels that has been created associate with this
inhanced lift has been studied in this thesis. The purpose of this study is the analysis of
the wigcraft ‘s aerodynamic and hydrodynamic behaviour. By considering the
dimensional similarity method, model simulation conditions are provided from the
prototype in one tenth scale in software. By doing this simulation, the final design of the
wigcraft is completed. First an overwiew of origin of the surface effect is given in the
introduction. Then review the problem-solving rules include how to use dimensional
similarity in simulation, has been explaned. Then in the wing aerodynamic chapter, the
requer airfoil cross-sections have been designed. By starting calculation, define the effect
of the surface by three-dimentional wing simulation exoressed in flight at different
altitude of the surface. Body selection, wing type and wing incidence angle to the fuselage
respectively to optimally select the geometry of the design, are done by simulation. Proper
flight velocity regime to meet flight needs, like a suitable flight lift, it has been tested in
different velocity rate, so that proper fluid velocity in the simulation is consistent with the
final results. Stability and control is the final part of the project completion process, which
ends with choosing the right design. The effect of the wave on the wigcraft in flight and
the buoyancy phase is the end of the simulation. In all stage of the research, it has obtained
three results at same time, comes with a design that is getting to know it with the step,
knowledge of the tool required for each design obtained. Method of preparation of the
wigcraft fluid simulation conditions is described. In addition to the supplementary design
obtained during the simulation process, the most plan has been prepared to access other
stages of industrialization
