Pressure on the upper surface of the hydrofoil is higher than the non cavitating flow in sheet cavitation. In general, propellers are used as propulsions and they are also used to progress significant plunge to propel the vehicle at its operational speed and RPM. Much has been said and published on the development of the marine propeller from the time of antiquity to the present age, but there is more to be done. This paper describes the design procedure of four bladed marine propellers with specific interest on engines with 85 Bhp and ship moving at a speed of 30 knots. ![]() Here different sections are considered to create single blade using HYDRO PROCAD and using section coordinate data 3D 4 blade propeller modeled in CATIA V5R20 and analysis are performed using FLUENT and ANSYS software. Material results are compared and the stresses obtained are well within the safe limits of elastic property of the materials.: Material Properties.: Comparative Table. Automatically Sections are created in Software. Construction of Hydrofoils by Joining of Points on Surface of the Blade.

Static analysis was carried out on aluminum, composite propeller which is a combination of R Glass, S2 glass and CFRP (Carbon Fib er Reinforced Plastics) materia ls. Here differen t sections a re c onsidered to create single blade using HYDRO PROCAD and using section coordinate data 3D 4 blade propeller modeled in C ATIA V5R20 and analysis are performed using FLUENT a nd ANSYS software. Material result s are comp ared and the stresses obtained are well within the safe limits of elastic property of the materials. Keywords: R Glass, S2 glass, CFRP, propeller, ANSYS, CFD Author for Correspondence E-mail: kspanitsg mail.com INTRODUCTION A propeller converts the engine power into the driving force of the ship. In conventional marine propellers standard propulsi on mechanism for surface sh ips and underwater vehicles are use d. When the local absolute pressure is less than local vapor pressure fo r the fluid medium, cav itation occurs. In fluid power applications the evaporation pressure is reached when flow velocity is increased sufficiently. Cavitation may lead to severe problems if it is not considered at design stage. As shown in Figure 1, the inception of cavitation on hydrofoil is a basic phenomenon in hydrodynamics which refe rs to the appearance of vapour phase when liquid flows around a hydrofoil. For thin hydrofoils at moderate angle of attack, the f irst occurrence of cavitation is closely related to the minimum pressure near the leading edge according to 1 -5. Under these conditions the inception of cavitation leads to formation of relatively large separated flow of vapour on the upper surface near the leading edge known as sheet cavitation.
