Hi.
I´ve began to work on the Sikorsky S76 just a couple of months ago and have a question.
Where could I find info about bifilar vibrations and the way the S76 dampens them.
I´ve seen in the configuration that it has a damper consisting of four masses with an excentrical movement. The problem is that this kind of vibration is absolutely new for me. My experience is with the Superpuma model from Eurocopter, and the only vibrations there where the ones from tail and main rotors. Don´t know how does it appear nor the mechanism to reduce it.
Thanks.
