WAGENINGEN CD-PROPELLER SERIES (original)

Running

The “Wageningen Propeller C- and D-Series” will provide open water characteristics in complete 2 quadrants for modern CPP designs, including blade spindle torque.

OBJECTIVE

The “Wageningen Propeller C- and D-Series” will provide open water characteristics in complete 2 quadrants for modern CPP designs, including blade spindle torque. Both open and ducted CPPs will be considered.

SCOPE OF WORK

Open water model tests will be conducted for a systematic series of CPPs and ducted CPPs. The number of cases which will be tested depends on the number of participants in the JIP. At this stage the following series is foreseen:

  • C4-40, C4-55, C4-70
  • C5-75
  • D4-40, D4-55, D4-70 in both 19A and 37 ducts

The tests will cover the complete range of pitch settings as well as both flow directions so that the complete 2 quadrants can be derived.

DELIVERABLES

Open water characteristics (propeller thrust and torque, and blade spindle torque) of the specified series of CPPs and ducted CPPs. The results will be delivered in diagrams and polynomials.

ORGANISATION

The work will be conducted by MARIN in the joint industry project “Wageningen Propeller C- and D-Series”. Participation is open to all interested companies such as propeller designers, navies, class, yards, DP system suppliers. Participation is confirmed by signing the JIP Participation Agreement with MARIN. The results and costs will be shared between these participants. Results will be confidential for 3 years after completion of the JIP.
