An air propeller is a device that converts rotational motion into thrust, which propels an aircraft through the air. It is one of the most important components of an aircraft, and without it, the aircraft would not be able to fly. In this article, we will explore the definition and meaning of air propeller in detail.
Definitions
An air propeller is a mechanical device that consists of two or more blades mounted on a central hub. When the blades rotate, they create a pressure difference between the front and back of the blade, which generates thrust and propels the aircraft through the air. Air propellers come in a variety of shapes and sizes and are used on a range of aircraft, from small single-engine planes to large commercial airliners.
Origin
The concept of using a spinning blade to generate thrust can be traced back to ancient times, where it was used in windmills and waterwheels. However, the modern air propeller as we know it today was first developed in the early 20th century. The Wright brothers, who are credited with inventing the first successful airplane, were also the first to use an air propeller to generate thrust.
Meaning in different dictionaries
According to the Oxford English Dictionary, an air propeller is “a device consisting of two or more blades that rotate to produce thrust and propel an aircraft through the air.” Merriam-Webster defines it as “a device that consists of two or more blades that rotate to produce thrust and propel an aircraft through the air.”
Associations
Air propellers are associated with aviation and aircraft. They are also associated with speed and efficiency, as they allow aircraft to travel faster and more efficiently than other forms of propulsion.
Synonyms
Some synonyms for air propeller include airplane propeller, aircraft propeller, and aviation propeller.
Antonyms
There are no direct antonyms for air propeller, as it is a specific device that has no direct opposite.
The same root words
The word propeller comes from the Latin word propellere, which means to drive forward or push. The same root word is used in other English words, such as propel, propulsion, and propulsive.
Example Sentences
- The airplane’s air propeller spun faster and faster as it took off from the runway.
- The mechanic inspected the air propeller for any signs of damage or wear.
- The pilot adjusted the pitch of the air propeller to increase the aircraft’s speed.
- The air propeller is an essential component of any aircraft, as it provides the necessary thrust for flight.
