... with non-autonomous combination hydrofoil system, measures and analyzes the draft, trim angle of model and law of resistance with the change of navigational speed, hydrofoil position and angle of attack, test results show that the trim angle of HYSWATH model is relatively small in hull-borne, transition...

... research pointed out that wind loads can stabilize the pitch motion of the floating wind turbine, but affect the trim angle more strongly than wave loads (Yasunori and Hiroyuki, 2010). That is to say, the trim angle is mainly caused by wind loads 115 while pitch motion is mostly caused by wave loads...

... instabilities are shown. The unstable phenomena are called porpoising and transverse porpoising, and the characteristics of them are explained. dynamic instability phase difference gravity hydrodynamic force katayama attitude trim angle amplitude equation cg 0 coefficient mechanism coupling...
