Eksperimentelle forsøg med WPP i modelskala
Projektstatus: Afsluttet
Baggrund
Simuleringer af propeller wake pitching indikerer, at drejes propellerbladene individuelt, således at de følger en pitch angle trajectory, forøges propeller virkningsgraden med op til 9,4 % og kavitation og støj midskes.
Simuleringsmodellerne er ikke tidligere anvendt til denne type beregninger og der er behov for eksperimentelle data til en evaluering af WPP konceptet og validering af de hydrodynamiske computermodeller for WPP.
Undersøgelsesspørgsmål
Kan WPP konceptet eftervises ved selvfremdrivningsforsøg og kan de hydrodynamiske computermodeller valideres ved åbenvandsforsøg i modeltank?

Resultater
There were two purposes for making the experiments.
One was to validate the performance improvement of the CVP propeller (WPP) experimentally. The results showed an improvement in the efficiency, but the
improvement was generally not large enough to be outside the uncertainty
bounds of the experiments. The other purpose of the experiments was to get
experimental data which could be used to validate the model established for
the CVP propeller. The reliability of the experimental results was not good
enough to be able to validate the different model components for the CVP
propeller. This has to be addressed in the future.
