Saving energy 1- 3%
The Eco-cap is designed to prevent vortices that originate at the roots of the blades of the propeller from concentrating at the end of the cap. The device suppresses the generation of a negative pressure region at the rear of the cap and reduces the resistance at the rear end of the cap, thereby improving energy efficiency. Although the cap body is made of NAB, the fins are made of FRP, and the fins have low resistance because of the thin blades. In addition, the number of fins is 7, and by shifting the phase with propeller blades, we can accommodate a wide range of fluctuating flows such as different ship speeds, revolution speeds and rough weather.
