Vessel propulsion with support vanes on rotary axis - has vanes moving at specified angle w.r.t. propulsion direction, with axis at different angle to that direction.
摘要
The propulsion vanes (1) rotate about a central point (2) ina plane parallel to the direction of travel. The vanes can be moved through a specified angle in the drive direction and their axis can rotate at a different angle in the drive direction. The design allows the vanes to travel from between two points in the water, thus doing work, while returning in the air to starting position. The vanes can be arranged on a band or chain behind one another in a row. USE/ADVANTAGE - For inland waterways, with buoyancy and resistancy contg. a component in drive direction.
