Attached above is a graph with rotor speed on X axis, altitude on Y axis and various All up weights, shown as a set of curves.Now for convenience assume all weight curves are parallel of constant slope and equidistant (In this graph they are not)
Is is possible to mathematically rework this graph so that X axis has the All up weight, Y axis continues to depict the altitude, and the set of lines now become the rotor speed? It can be done by physically plotting points......but is there a mathematical method to do it? If so what is the mathematical theory behind it, when is it possible to do such a conversion, and when is it not possible. Will be grateful for help.
