On the basis of results of theoretical calculations and model tests on Highly Skewed Propellers (HSP), solid type 46° HSP was designed for a car carrier 'Chijin-Maru' of 3, 200 carrying capacity according to the following primary plan; 1) Skew angle which decreases the vibratory propeller forces within the tolerable limit values is applied. 2) Blade strength of the HSP is higher than that of CP both in ahead operation and in crash astern operation. 3) Propeller efficiency and cavitation characteristics of the HSP are the same as those of CP or better. Especially, careful attention was paid for the blade strength in such a way that relation between HSP geometry and blade stress is fully examined by using propeller lifting surface theory and finite elements method. The 46° HSP design procedure is described in full detail in this paper. Model tests were performed to compare the performance characteristics of the 46° HSP with those of CP. Results of the tests demonstrated that the 46° HSP decreased propelle-rinduced fluctuating pressure by 37 percent on the hull surface and decreased sheet cavitation on the blade back without decreasing propeller efficiency. Then, the 46° HSP was applied to the car carrier and full scale measurements were carried out. The car carrier cleared design speed, required number of propeller revolution, estimated crash astern performances etc. at the official sea trial. Further, results of full scale measurements proved that propeller-induced fluctuating pressure measured on the hull surface was close to the value estimated by theoretical calculation or the model test and local vibration on the hull was in low level sufficiently in comparing with the other car carriers. Also, from results of full scale measurements it was confirmed that blade stresses measured in ahead operation and in crash astern operation were close to the estimated values and no problem was involved on strength of the 46° HSP. Adequately designed HSP can deduce vibratory propeller forces without lowering the other propeller performance characteristics and it should be considered to apply HSP to any ships with vibration problems involved.
