Description
Summary:Unmanned underwater vehicle (UUV) is an effective instrument to allow human to execute hazardous underwater mission without being exposed to life risk. Recently, UUV has gained increased popularity in the field of oceanography, underwater archaeology, underwater cable examination, military usage and hydrodynamic survey operation. Since aquatic animals have great capability to circumvent the drag underwater for efficient swimming compared with the torpedo-like man-made submarine, the morphology of aquatic animals shall be investigated in order to improve the efficiency of UUV. However, the complexity and non-linearity of their body shapes has hindered the formation of its morphological equations. Hence, this research aims to apply the mathematical model of moving least squares method to construct continuous equations which describe the bionic body shape of batoid and dolphin. The work will render geometrical support for computer-aided design and fluid dynamics analysis in the future.
