There are six new graphs in the calculator, including one that I have to call the first advanced graph.

A new propeller graph compares the Advance RatioRelates a propeller’s airspeed with the rotational frequency and diameter. It is closely related to the angle of attack of the propeller blades. with the Power-Speed CoefficientRelates the forward velocity with the power required to turn a propeller. It is closely related to a propeller’s efficiency. It is sometimes used to help determine the correct propeller diameter to use. . Both of these terms are in the glossary. If you don’t know what they mean, don’t worry about it. These quantities are very useful for conducting advanced propeller analyses.
