PURPOSE

Rudder-propeller unit ДРК750 type is designed for installation as propulsion device for marine and river vessels of various purposes.

DESIGN

The propulsion device combines both the propulsive and the steering functions. Propulsion is achieved by means of the propeller. Steering is achieved by rotating the pod over the entire circumference. This solution improves the ship’s maneuverability and propulsive performance.

The Scientific-Production Association “Vint” has developed technical documentation on the rudder-propeller complex of ДРК750 type with power rating 750 kW. JSC "Proletarsky Zavod" (Saint-Petersburg) has more than 40-year experience in mass production of various propulsion devices on the documentation developed by the Scientific-Production Association “Vint”.

JSC "Proletarsky Zavod" is planning to manufacture serially complexes ДРК750.

The “Proletarsky Zavod” has already proved the production technology of upper and lower reduction gearboxes with the mock-up outfitted with regular blocks and parts.

Depending on ship’s characteristics and operating area the complex ДРК750 shall be delivered with left or right rotation propellers, as well as with propellers with protecting covers or without them.
