AbstractAerodynamic interactions between 6 rotors on a multi-copter type drone are numerically simulated. The phase angles of the rotors and the pitch angles of the rotor blades are varied. The total thrust changes about 3% due to phase angle differences. With the phase angle differences between the neighboring rotors fixed to the smallest angle about 0 degrees (Worstcase), as the pitch angle approaches 16deg, the oscillating forces become relatively low. This property of the oscillating forces depends on the phase angle differences between the rotors, which is considered to be due to the shape change of the tip vortices.
