In order to achieve reliable ship operation, it is indispensable to check the dynamic strength of propeller blades in the early design stages. For this purpose, a modified quasi-steady approach was proposed for conventional propellers. This approach includes the introduction of an averaged wake with weight function along the chord, contradiction effect on the wake and a modification of Kito-Izubuchi's Beam Theory. The study was extended to cover problems with the strength of highly skewed propellers, which have recently become widely used to reduce propeller induced exitation forces.
