Review and correct discontinuities in FLOPS based ground effect #399

Open jkirk5 opened 6 days ago

jkirk5 commented 6 days ago

Desired capability or behavior.

from @dlcaldwelljr-ama-inc: FLOPS based ground effect can be applied to different degrees in the same phase, depending on aircraft and altitude:

The current implementation relies on np.where() to determine which degree of ground effect applies to which points in the analysis. This can (does) introduce discontinuities in the analysis.

The regions of ground effect do not always (often? ever?) line up with boundary conditions for convenient phases, but there may be a way to mitigate the discontinuities.
