Pumpjet propulsor (PJP) is widely used in various underwater vehicles recently. Two types
of PJP, the stator-rotor PJP (the rotor is behind the stator) and the rotor-stator PJP (the rotor …

The effects of different stator pre-whirl angles on the hydrodynamic and noise performance
of a pump-jet propulsor (PJP) are studied; these angles are the inlet, outlet, and stagger …

In this work, the verified mesh is employed to study the effect of the stator number (Ns) and
rotor number (N r) on the pump-jet propulsor performance. Based on the RNG k–ϵ …

This work studies the effect of the asymmetric pre-whirl stator spacing on the hydrodynamic
performance of a pump-jet propulsor (PJP). The PJP contains a 13-stator and 7-rotor. The …

This research examines the novel use of a postswirl propulsor to generate side forces
sufficient for undersea vehicle control. Numerical simulations using the commercial …

There is a growing need within marine sciences and engineering that requires the torpedo
shaped Autonomous Underwater Vehicles (AUVs) being capable of accomplishing various …

Previous computational and experimental studies that have demonstrated a method to
generate vehicle maneuvering forces from a propulsor alone have been applied to a generic …

The design method for marine propulsor (propeller/stator) is presented for an autonomous
underwater vehicle (AUV) that operates at a very high loading condition. The design method …

A method to generate vehicle maneuvering forces from a propulsor alone has been applied
to a generic undersea vehicle. Open and ducted post-swirl propulsors were configured with …

The fundamentals of circumferentially varying stator cascades and their interactions with a
downstream fixed pitch propeller were investigated experimentally utilizing multiple …
