[Abstract]:Taking the snake monster lizard as the bionic object, based on the high speed movement behavior of the snake monster lizard driven by the rotation of the thigh of the snake monster lizard, the surface bionic vector thruster is designed, which increases the output dimension of the driving force and realizes the controllable lifting force, propulsion force and torque output. Combined with RNG k-蔚 turbulence equation and PISO algorithm, the hydrodynamic model of thruster is constructed, the optimal design shapes of blade radial and axial are obtained, and the mathematical functions of driving force and blade length and width are derived. Finally, the test system of vector thruster is built to verify the correctness of the numerical calculation model, and the prototype test of Amphibious vehicle is carried out, and the driving body of vector thruster realizes water skiing in the state of 10.6 擄elevation angle, which provides a new idea for reducing drag and increasing speed of water surface device.
