Because of the upwards pressure of the water the propeller keeps drawing up water much longer than for example a tunnel thruster for boat. Veth Motoren has made a model test in which case the thrust remained equal up to 10 knots. The thrust of the Veth-Jet is high. Per kW about 11 kg of thrust is obtained. The propeller can be optimized in 1 turning direction and in comparison with other systems with horizontal mounted marine propellers there is a minimal turn of the water and a horizontal pressure. Besides the in house for boats development there is a close cooperation with several research centers. The pictures below show tank for boats tests during which thrust was measured on a sailing ship. | | | | | | | | | | PRINCIPLE OF OPERATION | | | | | | | | | | 0 IBëD30? | | | | | | | | | | | | | | | | |
