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. |
