SOME PROBLEMS OF STRENGTH IN HYDROFOILS

NEKOTORYE VOPROSY PROCHNOSTI PRODVODNYKH KRYLEV

The strength of hydrofoil systems is determined by the fatigue characteristics of welded joints. Static design stresses in designing hydrofoil systems can be increased for ductile materials where t/h0.1-0.15 due to the increase in the yield point on bending. Ductile steels of average strength having good welded joint fatigue characteristics should be considered the optimal material for hydrofoil systems. The repairability of steel (even that recommending itself most highly in operation) is limited, and according to the first tests on testpieces, does not exceed 15 percent. (Author)
