The interaction of propellers or rotors with the aircraft fuselage plays an important role in overall aerodynamics, stability, and infrared signature. FLUENT facilitates this type of analysis, with fast meshing of complex geometries and robust models for rotor simulation. Rotors and propellers can be handled with lumped parameter models or by using more detailed multiple reference frame modeling options.
