702 semi-immersion paddle equipment re-innovation

Recently, the 300 kW semi-immersion paddle and transmission developed by 702 successfully completed the actual ship test in Shenzhen Bay, South China Sea. The maximum speed of the test ship reached 40 knots at no load and full load. The trim and rudder operations were flexible and fully met the design specifications. It was a complete success.

Semi-immersion technology is a new type of technology. Its high efficiency and non-cavitation characteristics make it one of the mainstream products for speedboats in various countries. The 300 kW semi-dip paddle device is a 702 new product development and industrial cultivation project. On the basis of the successfully developed 235 kW semi-impregnation principle prototype, the structure has been greatly improved, and the weight of the whole machine is more reasonable. The structural performance is further practical and has a good market prospect. The project development team will further improve and improve the model and combine it with the problems found in the trial.
