Brief Description:

What is a Propeller?  A propeller is a type of fan that transforms rotary motion into thrust. It is commonly used in various vehicles, including:

  • Aeronautical applications (aircraft)
  • Aquatic applications (boats and submarines)
  • Propellers work by generating lift through differential air or water pressure. When a propeller spins, the shape and angle of its blades create high-pressure zones on one side and low-pressure zones on the other, thus propelling the vehicle forward.
  • A tachometer is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute on a calibrated analogue dial, but digital displays are increasingly common

So.................

lets find out how to use them and how accurate are they?
