Rudder Measuring Instrument

Rudder Measuring Instrument

Measurements can also be taken with the ship model manoeuvring, while the rudder to be tested is adjusted to various rudder angles. Balance rudders as well as rudders supported on a helm post can be tested with the instrument. In the latter case, lift and resistances are measured for the combination of rudder and helm post while torque is measured at the rudder only.
