Sailboat propeller design

Propellers propulsion design choosing efficient, The propeller screw design stabilized by the 1880s. in the early days of steam power for ships, when both paddle wheels and screws were in use, ships were often characterized by their type of propellers, leading to terms like screw steamer or screw sloop. propellers are referred to as "lift" devices, while paddles are "drag" devices.. Tutorial design propeller plane optimize, Following the tutorial propeller aircraft design (1/2). knowing: the optimal speed of the engine: 8000 rpm (one that offers the most power consuming less energy, it is the motor's design rotational speed ) the torque of our engine at this speed is 1,9 n.m ; the speed of our aircraft in cruise flight: 180 km/h the drag of our plane: 30 newtons the maximum length of our propeller blade: 140 mm.
