MIT comparison analysis of Deep Sea Systems'
TH-2100 Thruster |
Dear Chris,
We are extremely impressed with the
performance of your thruster with the Parker
Drive Blok controller. The system proved to
be very reliable and provided huge thrust
with a quick response time. We tested the
thruster in the propeller tunnel under a
variety of conditions. With the Drive Blok
controller, the thruster would start quickly
even when the propeller was being back
driven by the flow at 4 m/s. We estimated
the propeller efficiency and the overall
system efficiency using the our force and
flow speed measurements together with the
torque and angular speed estimates from the
WinControl software. We found the electrical
system efficiency to be very high, always
above 80% and typically above 90%. The
propeller efficiency was decent, with a
maximum of at least 41%. The dynamic
response of the system was impressive. A
step from zero thrust to full thrust takes
0.75 seconds, and a step from full thrust
forwards to full thrust reverse takes 1.1
seconds.
We would be happy to give this product a
strong recommendation.
