Experimental investigation of the flow on a simple frigate shape (SFS). [PDF]
ScientificWorldJournal, 2014 Helicopters operations on board ships require special procedures introducing additional limitations known as ship helicopter operational limitations (SHOLs) which are a priority for all navies. This paper presents the main results obtained from the experimental investigation of a simple frigate shape (SFS) which is a typical case of study in ...
