[A/S] "Yaw Sensor"

[hhamp5246@xxxxxxx]

Hi Gang,

I wrote about Tony's unfortunate roll over on the rv newssgroup and got this 
back from one of the members..... have any of you ever heard of this thing?

"Sorry to hear of such a nasty accident but glad no more than minor
injuries resulted.

Many years ago, when I was in airplane handling qualities research, I
was surprised to hear that a friend's Holiday Rambler TT was equipped
with a yaw damper. I thought such devices were airplane systems, not
on a relatively mundane travel trailer. This was back before all the
clever digital stuff we take for granted these days was on the market,
even before PCs were introduced.

Apparently, a yaw acceleration sensor was mounted under the frame at
the back of the trailer. An electronic controller then applied brakes
on the appropriate side of the TT to straighten things out. I guess it
must have worked with electric brakes.

I'm surprised that an expensive rig like an Airstream didn't have such
a system, or have they disappeared from the marketplace? Since we're
MH owners, I've never thought about those kind of stability issues."
