Default Need Help on Landing Gear Calculations

I'd rather not drop my plane with engine G but am looking for a way to
just test the gear assembly. Was thinking ; restrain the top connection of
the gear leg and apply a uplifting force on wheel via some sort of lever
setup.

Can't get my mind around any method of dropping the gear assembly and would
appreciate some thoughts..

SECOND: What setup could be used to do such a load test??
Is it mandatory to actual freefall drop or somehow just apply the load??


I vote for a drop, so it rings like a bell. A steady load won't be the
same.


Untrue. Force is force. If you can calculate how much pressure is put on
the gear, by taking into account the weight of the craft, and the height
at which it is dropped, a steady load is the same. It could be even more
stress on the gear, because factors such as tire deflection will not be
taken into account with a steady force test, and it would actually
decrease the amount of force put on the gear in the drop test. Bear in
mind that it will be a very sizable load, though! g

I myself, would rather do the drop test. Less sandbags to fill and place,
and the drop would make a really good video, too! :-)
