HUB SIZE SELECTION CRITERIA FOR CONTROLLABLE PITCH PROPELLERS AS A MEANS TO ENSURE SYSTEMS INTEGRITY

In a CP propeller the size of the hub largely influences the reliability of the system in operation. Accurate choice of the hub-size provides the best means to prevent the system from structural propeller failures and is therefore the best method to ensure reliability and optimized performance. Recent failures of high-power CP propellers, of which one Navy propeller had a serious mission failure, could have been avoided if a larger hub had been adopted. The paper contains two tools, available also to non-specialists. One allows clear recognition of the technical degree of difficulty of all types of propellers and the other is a scale to determine the degree of load of each CP propeller hub. Information is given concerning the influence of the hub/diameter ratio on the hydrodynamic performance.
