AbstractAerodynamic interactions between 6 rotors on a multi-copter type drone are numerically simulated. The pitch angle of the rotor blades and the distance between the rotors are varied. It is found that 2-6/rev fluctuations in the resultant forces and moments are significant due to the interactions between these 6 rotors. These oscillating forces and moments are considered to be the main sources of vibrations on the multi-copter type drone. The thrust of the drone is controlled by change of the rotor pitch and the fluctuations change in nearly same proportion with the resultant thrust. When the distance between the rotor is below half of the rotor radius, the intensity of the interaction increases abruptly to about 3 times while the rotor performance improves about 20% compared with the wide rotor distance cases.
