 Posted: Mon Jun 14, 2010 8:30 pm Post subject: Wheel Balance and shimmy - an update |
 |
|
I previously reported that wheel balancing didn't appear to affect my landing gear shimmy. Well, I wasn't doing an apples to apples comparison, because I decided to fly without the wheelpants and fairings to do a quick check.
The weight of the wheelpants would obviously affect the resonant frequency of the gear, and that never crossed my mind.
Today I finished some mods to my wheelpants and reinstalled them and went flying. I was surprised to find that on landing I had the slightest, barely noticeable shimmy just before turning off the runway. I was so surprised that I taxied back out and did another circuit. Same results.
There are other variables compared to last time (such as the 100 degree heat!) but I am optimistic that the wheel balancing did actually address the shimmy issue to my satisfaction. It used to be bad enough that if I was transmitting when it happened I sounded like I was in a helicopter. Now I think a passenger wouldn't even notice.
Good stuff.
If anyone wants to drop by the Dallas, Texas area and balance their wheels they're more than welcome to the hanger.

Thinking back, the same thing happen with me. I never made a connection.
