The collective and cyclic pitch propeller (CCPP) is a propulsion and manoeuvring system for Autonomous Underwater Vehicles (AUVs). Through control of the propeller’s blade pitch the CCPP is capable of generating propulsion and manoeuvring forces in an effective and efficient manner at both high and low speeds. Recent studies identified the need for additional research into the CCPP’s unsteady flow behaviour and force generation capabilities before the technology can become a usable propulsion and manoeuvring system for AUVs. The paper discusses the development of a unsteady Reynolds-averaged Navier-Stokes (RANS) based numerical model. The motion of a single propeller blade is simulated by applying a sliding mesh approach and periodic boundary conditions to investigate the CCPP’s hydrodynamic performance. After initial assessment of the methodology through verification and validation, a first numerical study is set-up to investigate the effect of cyclic pitch variation at zero collective pitch and without forward velocity. The results established the capability of the CCPP to produce a manoeuvring force, which increases in magnitude as the pitch amplitude is increased. Additionally, the blade rake angle was proven to have an effect on both the orientation of the manoeuvring force and the magnitude of the generated thrust force.
