ANALYSIS OF DRAG AND LIFT FORCES IN DIFFERENT TAILED GROUND EFFECT VEHICLES

In recent days people are dependent highly on transportation and the demand for quicker modes of transportation are increasing day by day. Technological advances in the areas of roadways, airways and waterways have led to development of faster and efficient vehicles which has largely contributed in connecting people across the globe. This study deals with finding the effect of different forces acting on Ground Effect Vehicles. Initially three different tail models were considered and modeled in CATIA and then imported to ANSYS for further analysis. It was observed that the higher pressure at tips is a result of the shape of the GEV and it causes drag, since it is opposing the inlet flow. Lift is generated due to difference in pressures between top and bottom surfaces of the wing, which is a consequence of velocity difference. The pressure at top is much lesser that than bottom of the GEV, so lift is also generated. However, it was found from L/D ratio that V tail displayed higher response for the considered process parameters and boundary conditions.
