Abstract
This paper proposes a new spiral drive system that utilizes the impeller to absorb the kinetic energy of the fluid, which has many advantages, which has many advantages, such as stable operating speed, small required start-up flow rate, large pulling force, and strong barrier-crossing ability. In order to verify the practical feasibility of this assumption, this paper firstly constructs a theoretical framework based on momentum-leaf vein analysis, and analyzes the force on the drive system. Subsequently, the tensile force test is conducted on the test prototype through the experimental platform, and the motion trajectory of the prototype and related data are recorded. The experimental results show that the main power source of the drive method is the torque generated by the impeller, while the impact force of the airflow has relatively little effect on the drive system. What's more, the drive system is able to obtain more sufficient power, thus fully proving that the impeller-driven spiral walking drive method is completely feasible.
