How does the Prince P-TIP propeller change pitch?
The method the Prince propeller changes pitch is due to the amount of pull the propeller has. When a propeller is at high rpm and slow airspeed the forward face of the blade has the greatest pull. When the propeller reaches the designed airspeed the propeller face has zero pull. To take advantage of this condition we taper or sweep the leading edge of the Prince propeller profile. When the propeller pulls or cones forward in this high rpm slow airspeed mode the outer portion of the blades pull forward. As the blade pulls forward it will untwist the propeller and offer about 4″ less pitch. The pitch will start to move back to the higher pitch carved setting as the airspeed increases. An example of the pulling forward or the proper term, Coning, can be seen on helicopters and propellers if you are looking for it. You may have noticed a helicopter rotor in static running the rotors are straight out or running horizontal, when the collective pitch is applied the blades are now in a bowl sh
