I guess the question to ask is everything else being equal, is static thrust one indicator of a props performance or not? In other words setting a fixed prop on a tandem pusher gyro, for a Rotax 914 to deliver say 5400 RPM at max RPM on the ground, is static thrust not a measure that can be used to compare two props at least at those parameters? If not, why not? I understand hat this does not automatically mean the props will be comparable in all situations, but it would seem reasonable that static thrust can be used as a reliable starting point. I guess the next question to Fara is: Is there data to show that there is no connection between static thrust and other forms of measurement or is there a linear relationship? Do prop manufacturers have this type of data?
Yes they are a measure of which prop produces more static thrust for sure. What I am saying is that that measure is a bit useless and unfair if you are looking for a good prop for say your MTO. Even though gyroplanes are slow they are not flying at 30 to 40 mph
