screw propulsion

Screw propulsion, also known as propeller propulsion, uses a rotating blade (propeller) connected to a motor to generate thrust. As the propeller spins, it pushes air or water backwards, which in turn moves the vehicle forward due to Newton’s third law. This method is commonly used in boats, ships, and airplanes. The design of the screw, including its size, shape, and pitch, affects how efficiently it converts rotational energy into forward motion. Overall, screw propulsion is a reliable and effective way to move vehicles through fluids by producing continuous, controlled thrust.
