Ship Propeller

This example shows a marine propeller represented by a Propeller block from the Simscape™ Driveline™ library that propels a ship. The propeller starts from rest while the current pushes the ship forward. The ship accelerates as the Ideal Angular Velocity Source starts up the propeller. After 500 seconds, the propeller spins at a constant speed, and the ship approaches a constant speed. Ship motion is resisted by a drag force that increases quadratically with ship speed.
