Ice class strength
A complete controllable pitch propeller system for ship propulsion might consist of propeller blade, propeller hub, blade carrier, blade bolts, crank pin, guide block, retaining wall, push-pull rod, servo, etc. All these components should satisfy the static strength requirement and fatigue strength requirement, including crankshaft fatigue, in the design. Especially, for ships navigating in Arctic areas, the controllable pitch propeller system has to satisfy the relevant ice class rule in this area.
Nauticus Controllable Pitch Mechanism tool supports both main class and ice-class strength calculations. It can efficiently determine the strength capacity for all components of controllable pitch propeller and gives all the criterion results in the text according to the code checking requirements.
