Notes

The Prop_Rotor class models rotors designed for both hover and forward flight, typical of tiltrotor aircraft. It includes capabilities for:

  • Hover and cruise performance analysis

  • One engine inoperative (OEI) conditions

  • Variable pitch operation

  • Acoustic analysis

  • Performance optimization

  • Multi-mode operation

Definitions

‘OEI’

One Engine Inoperative - emergency condition where one engine fails

‘SPL’

Sound Pressure Level - measure of acoustic intensity

‘Tip Mach’

Mach number at the blade tip, including rotational and forward flight effects

‘Multi-objective Performance’

Combined optimization of multiple performance metrics
