摘要

The quasi-steady measurement technique, the latest development in propulsion testing by MARIN, comes under the spotlight.rnIn the quasi-steady technique a gradual variation of the rotative speed of the propeller is imposed, while the forward speed of the model is kept constant. Thus, the load of the propellers continuously changes during the measurement run. An essential assumption of quasi-steady experiments is that each instantaneous condition encountered during the quasi-steady test is representative for the corresponding steady condition.
