Notes

The Lift_Rotor class models rotors specifically designed for vertical lift applications. It includes capabilities for:

  • Hover performance analysis

  • One engine inoperative (OEI) conditions

  • Variable pitch operation

  • Acoustic analysis

  • Performance coefficient calculations

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
