Default Need Help on Landing Gear Calculations


"Dick" wrote

Just thinking out loud here but thought the +/- 6 G was for airframe, etc in
flight while the landing gear get subjected to considerably less. Vaguely
remembering the FAA requirements as 3 times static wheel load dropped 19". I'm
thinking 300# on one mains times 3.


True, the G rating for an airplane is for the airframe, but how many G's would a
drop from 19" develop?

I don't have the slightest idea. I'm not a wiz on math problems.

If a drop from 19" does not stress the plane to more than 3 G's, that would be a
wimpy test, in my opinion. A plane dropping in on a blown landing hits with a
real whack. How about it, you out there with G meters? How high of a reading
have you seen on a really blown landing?

It should not be that tough, for a wiz at math to figure out how hard of a whack
a 19" drop generates. Take the speed generated, and divide that result out into
the amount of suspension travel, I would think.

The whole key in the difference is that the G rating for an airframe is
generated and suspended by the wings, and the G rating for the landing gear is
generated by changing velocity into a stop by the landing gear.
