How A Propeller Works

how a propeller works

A propeller is a device with a bladder that spins around to make objects move. If you want to move, use the air and force to push backwards. Just like your feet. 

Why planes need propellers. 

The twisted airfoil shape of an aircraft propeller was pioneered by the Wright brothers.While some engineers had attempted to model air propellers on marine propellers, the Wright brothers realised that a propeller is similar to a wing, and were able to use data from  their earlier wind tunnel experiments.

about the propeller.

The propeller is an object on the plane that spins around to create thrust, so without the thrust the plane cannot fly. A propeller is a machine with parts called blades. Each blade is shaped like a bird's wing. There are only three blades on a propeller.

more about the propeller.

Propellers make the plane move forwards,which creates thrust. When an engine blows the blades the propeller spins and then the plane takes off.


So now we know that a plane can't fly without a propeller.Without a propeller the thrust will be lost so it cannot fly.

    You have included interesting information in your explanation.
    Can you now go and check that punctuation is all correct because when you publish on your blog your work must be accurate.
