Light on rotor
The Sultan is correct! More simply put the S-92A is short on rotor. It has been said before on this forum, “the S-92 was proposed as a growth S-70.” As the weight grew the rotor did not follow in proportion. As the gross weight grew form 22,220 lbs in 1993 to its present weight of more than 27,000 lbs. (21.5%) the rotor diameter was increased 2.66 ft. and the rotor speed was increased from 258 to 271 rpm. These fixes were aimed to expedite the fielding of the machine, but may have resulted in some of the present issues.
