Propellers

Propellers are rotating blades used to propel a vehicle, typically a ship or aircraft, through a fluid medium such as water or air. They generate thrust by accelerating the fluid in one direction, resulting in a corresponding force propelling the vehicle in the opposite direction. Their design is crucial, as factors like blade shape, pitch, and number affect efficiency and performance. Modern propellers are often made from lightweight and durable materials like aluminum alloys or composite materials to enhance fuel efficiency and maneuverability.

Propellers meaning with examples

• The massive ship rumbled to life, its powerful engines driving the propellers, churning the water into a frothy wake. The sailors felt the vibrations as the ship slowly began to move, its propellers working hard to overcome inertia and gain momentum. Their voyage to the uncharted islands began, powered by the relentless motion of the metal propellers.
• As the small airplane taxied onto the runway, the pilot revved the engine, causing the propellers to spin into a blur. With a surge of power, the propellers bit into the air, pulling the aircraft forward. Soon, the plane soared, fueled by its whirling propellers, quickly gaining altitude as it headed toward the distant clouds.
• The research submarine dove into the ocean depths. Its propellers quietly maneuvered the vessel through the dark and unexplored waters. Underwater, the crew relied on the efficient operation of the propellers to reach a specific location, documenting their discoveries as the silent propellers guided the craft.
• On a hot day, the owner activated the giant fans, whose propellers provided the cooling and air circulation, allowing them to breathe easier. The whirring of the large propellers created a gentle breeze throughout the entire venue. The simple propellers worked with consistent efficiency, driving the fans to provide a relief during the heat wave.
