3 Per Rev Vibration in Helicopter Rotor System 1

[RotorHead269]

Hello Everyone,
Needing some help/ideas on locating abnormal vibration in Hughes 269 rotor system. Have been dealing with the "experts" in the industry, but absolutely no success in correcting this. I have a lot of vibration data logged with a MicrovibeII analyzer that can be emailed if necessary. If anyone has an interest in assisting me with this, your effort would be greatly appreciated. Thanks in advance.

Thank you for the suggestions. I really didn't know where to start searching as this is an unusual situation. I'll give them a try. I assume your local since you know the area?

Just wanted to thank you again. I contacted a Professor at TU that is going to help me out.

Professors love these type problems. They get a chance to get out of the classroom and exercise their mental muscle.

Let us all know what the ultimate problem and solution ends up being.


Good luck,

Steve
