With decades of experience, we know how to design and manufacture the best propeller to match your vessel. Using the latest technology, together with our years of design expertise, we can develop the optimum state-of-the-art propeller to meet individual needs.
In order to optimize the performance of luxury yachts, ferries and warships, Hung Shen has developed a NEW Silent Propeller (NSP) series. The use of this 4 or 5 blade advanced propeller will reduce propeller induced vibration and noise levels dramatically. The new foil section, makes the blade sections much less sensitive to cavitation when operating in the non-uniform inflow common to yachts, ferries and warships. The NSP series reduces ship vibration level approximately 50% and cabin noise level approximately 3dB (A) for luxury yachts. At the same time, it increases the propeller efficiency for high-speed craft. The ship speed can be increased by approximately one knot for ships with maximum speed around 30 knots. To focus on vessel speed over 25 knots, Hung Shen has developed a new propeller series which out-performs pervious propeller series.
We have performed a series of model propeller tests considering different expended area ratios ( 0.75 & 1.0), number of blades ( 3, 4 & 5), inclined shaft angles ( 0, 6, 8 & 10 degrees) and cavitation numbers ( atm, 1.0, 0.75, 0.6, 0.5, 0.45, & 0.4), and have formed a complete propeller series.
