Aerodynamic Analysis of a Wall-Climbing Robot with Dual-propeller

Abstract

A wall-climbing robot is a mobile robot that operates on a vertical wall. A wall-climbing robot with dual-propeller is proposed in this paper, in which the aerodynamics of the propeller is an important research part. Therefore, the aerodynamics of the propeller is simulated by ANSYS Fluent and experimentally analyzed in this paper. First, the aerodynamic simulation analysis of the single rotor and the double rotor is carried out in this paper, and then the tensile test experiment of the single propeller is carried out by using the pulling machine. Finally, an experimental platform for the whole machine was built, and the tensile test experiment was carried out on the double propellers. It is concluded that the aerodynamic forces generated by the two rotors are not linearly superimposed due to the airflow interference, and the rotational speed of the rotors and the distance between the rotor platforms all affect the magnitude of the force.
