Pumpjet propulsor (PJP), as a new type of propulsion system, is widely used in underwater vehicles. A propeller noise reduction technology using sawtooth duct is proposed and applied for the first time to PJP. In this paper, a normal PJP model and a PJP model with the sawtooth duct ...
Design of a Pump Jet Propulsor (PJP) was undertaken for an underwater body with axisymmetric configuration using axial flow compressor design techniques supported by Computational Fluid Dynamics (CFD) analysis for performance prediction. Experimental evaluation of the PJP was carried out through experime...
