Analysis of information sources in references of the Wikipedia article "AeroVelo Atlas" in Portuguese language version.
The graph shows how the induced power is reduced in proximity to the ground, where h/R is the fraction of the height to the rotor radius.
The Atlas is the second-largest helicopter ever built–154 feet from rotor tip to tip–according to AeroVelo (the Mil V-12 is the largest)
Atlas has a rotor diameter of 66.2 ft., total span of 153.9 ft. and disk area of 13,730 sq. ft.—making it larger than any production helicopter.
With a maximum diagonal dimension of 154 feet (46.9 meters), Atlas is the second-largest helicopter ever built, coming in behind the Russian Mil V-12.
