pfrabott Posted July 20, 2009 Share Posted July 20, 2009 What is "Rotor in Ground" mean? I saw it in the takeoff area of the manual. After looking at it RIG and non-RIG look the same on paper. what am I missing? Link to comment Share on other sites More sharing options...
EtherealN Posted July 20, 2009 Share Posted July 20, 2009 http://en.wikipedia.org/wiki/Ground_effect_in_aircraft "A helicopter hovering close to the ground will require less power than when hovering out of wing in ground effect. The effect occurs when the helicopter is within one blade length of a hard surface." "When operating in ground effect, the downward and outward airflow pattern tends to restrict vortex generation. This makes the outboard portion of the rotor blade more efficient and reduces overall system turbulence caused by ingestion and recirculation of the vortex swirls. Rotor efficiency is increased by ground effect up to a height of about one rotor diameter for most helicopters."
