S92 Gets 5 M/R Blades???
It's a rumor network and this is certainly a rumor.
Had a telephone conversation today with a well informed rotary-wing journalist. Rumor has it there may be a delay in the S92 program because Sikorsky is considering (or will) modify the aircraft to a 5 bladed Main Rotor head.
I'll believe it when I see it, but reason given for the modification is vibration.
Cheers
