Abstract

In a counter rotating propulsion system (CRP), whereby the aft propeller ( 22 ) and the forward propeller ( 6 ) have opposite directions of rotating and the aft and forward propellers are arranged against each other, the forward propeller is provided with a hubcap ( 30 ), wherein at least two equally distributed flow plates ( 28 ) are arranged on the cap ( 30 ) and the flow plates ( 28 ) are radially projecting from the cap ( 30 ).
