An Experimental Study of Flow Around CPP Blade (3rd Report)
Measurement of CPP Blade Spindle Torque
By Masamitsu ITO (Member), Shosaburo YAMASAKI (Member),
Masamitsu OKU, Hajime KOIZUKA, Masahiro TAMASHIMA (Member)
,and Michihito OGURA (Member)
The hydrodynamical component of CPP blade spindle torque that plays an important
role in CPP design, is investigated.
The hydrodynamical blade spindle torque of two model propellers (MP. B 82--1 and
82 2) was measured by the newly developed support-pillar type blade dynamometer in
circulating water channels.
Measurements for two propellers in the uniform flow field indicated that the
maximum value of hydrodynamical blade spindle torque occured at the maximum
reverse pitch setting and near the bollard condition ( / = 0 ) and the dominant factor
influenced on the hydrodynamical blade spindle torque was blade contour.
Fluctuations of the hydrodynamical, blade spindle torque of MP. B 82-1 in the
simulated non-uniform flow field with the wire mesh were measured. Although means
are much different, fluctuations were nearly same for the pitch setting angle from-10
to 10 degree. It is also seen that the means in the non-uniform flow fields were a little
higher than the values in the uniform flow at the same operating condition (same thrust
condition).
Comparisons of calculated values by the lifting surface method and measured values
at the design and the maximum reverse pitch setting conditions were made and they
showed good agreements. Then in order to use at the early design stage, spindle torque
estimating charts of AU-CP series CPP were drawn based on the lifting surface
calculations.
