Unsteady numerical simulation method was utilized to study the characteristic of blade dynamic loads under the rotor-rotor interaction in a high-load vaneless counter-rotating compressor. The study showed that: the unsteady pressure pulsation of upstream rotor originated from the shock wave sweeping of the downstream rotor. It mainly concentrated near the pressure surface trailing edge after the upstream rotor blade ending shock wave. Its maximum pulsation intensity was
