Negative drag result

Jonah LepakJonah Lepak asked 2 years ago

The “part force” results in a negative Fx number for my main wing at AOA above 3 degrees or so. This happens in both type2 and type6 analysis. CL, CD and Drag (N) all appear to be correct. Fx for elevator and fin are also positive and appear to be correct. Low AOA op points also appear correct for the main wing with a positive Fx that correlates to the L/D ratio.
