An overview of all input parameters is given:
Tests have been carried out with speeds at full scale of:
Tests without propeller rate and at three different propeller rates have been carried out:
Tests have been carried out at five different drift angles:
Tests have been carried out with a "drift angle" of 180° to investigate the asymmetry of the propeller on the bank effect. In most cases the bank is at starboard. With a "drift angle" of 180° the bank is at the port side of the ship.
topExcept for validation all static tests have been carried out without deflection of the rudder. Multi modal tests have been carried out at each bank and each propeller rate. A harmonic variation is enforced on the rudder during a multimodal test.
topFive different distances to the bank have been investigated:
The bank effect of the port side bank compensates the bank effect of the starboard side bank.
The ship sails at the centre line of the towing tank.
The side of the ship closest to the bank sails above the start of the sloped bank. This is the most lateral position with a constant under keel clearance.
The midship is located above the tip of the sloped bank.
The maximal later position possible.
topTests have been carried out with different water depths. The UKC is expressed as a percentage of the draught.
