Rotor friction and/or parasitic blade drag non-existent in SU2 beta

Version: 1.4.18.0

Frequency: Consistently

Severity: Blocker

All helicopters

Bug description: when decreasing throttle from “flight” to “idle”, there’s close to zero deceleration of rotor PRM, thus indicating, that there’s no rotor friction and/or no parasitic blade drag taken into account by CFD

Repro steps: reproducable with every helicopter in MSFS2024
