Abstract :
The present work attempts to evaluate the functionality of an ellipsoidal head designed and fabricated for improved hydrodynamic performance of a high speed under water vehicle, which is predominantly used in defense applications. The importance of proper geometric shape for head portion of an under water vehicle is studied by the performance evaluation of different profiles through computational analysis. It is identified that the hydrodynamic performance of the vehicle can be improved with head having ellipsoidal profile. The designed vehicle having ellipsoidal heads of different major to minor axes ratio is fabricated and tested experimentally to validate the computational results.
