In order to insure the large controllable pitch propeller’s reliability in its whole life cycle, it should be exhaustively tested. Water test is important and necessary, but due to its difficulty and high costs, ground tests are more widely used. This article focuses on dynamical loads simulation of large controllable pitch propellers, which is the key problem of ground tests. A centrifugal loading device was designed by the principle of couple to simulate the loads of bending moment and blade spindle torque to pitch control mechanism, and it was confirmed by finite element analysis. Finally, the dynamic loading test system was proposed for large controllable pitch propellers onshore tests. The results of stability pitch test and controllable pitch test show that the simulation is effective and accurate.
