Propeller 3D model

cgtrader

A spinning hub and radiating blades that form a spiral shape when set at a pitch, mimic the action of Archimedes' screw. By converting rotational energy into linear thrust, it uses the working fluid to move forward or backward. When rotated, the propeller's motion creates pressure differences between two surfaces, accelerating the fluid in one direction and propelling the craft in the opposite way. Like aircraft wings, propeller dynamics can be modeled using Bernoulli's principle and Newton's third law. Marine propellers typically feature a horizontal axis shaft with rotating helical blades that resemble a screw shape.
