Jul 29, 1973 : S-69 ABC (XH-59)
The ABC (Advancing Blade Concept) was designed to prove the viability of two counter rotating main rotors on a common axis as a means of achieving higher speeds and better agility
Its simple design eliminates the tail rotor for anti-torque and directional control. Rudders in the twin tail are used instead, as in a fixed-wing aircraft
The concept also offers lower operating and maintenance costs. The ABC has been extensively flight tested as a pure helicopter and, with auxiliary propulsion, flown at speeds in excess of 480 km/h
This system had the additional advantage of eliminating noise caused by the tail rotor and its transmission.
XH-59A serial number 73-21942.
