I've designed two turbines around a 500-600 watt Chinese alternator. They will use a flip up governor, like the old Parris Dunn units. I've had 2 big springs custom built for the job and the simulation suggests that the response will be very linear.
I just wanted to ask anyone who has observed the old Parris Dunn units in action, how hard they come down, after governing. I would imagine that, if they're up high enough, in a nice air stream, they would probably come down in a smooth fashion but I haven't seen one running.
I ask this because I'd like to have an idea of how much shock absorption I need to build into the unit ; a chunk of rubber, or just metal to metal.

Any help would be appreciated.
