lets have a discussion about ground handling loads. A recent thread "doubler damage tolerance analysis" was concerned with adding a blade antenna to a plane (assume to the fuselage). obviously loads (other than cabin pressure) are a concern, and the poster was looking into aero. loads.
my experience is at unless the blade is very big, or unusual geometry, or the plane very fast, then aero loads aren't significant. so we consider a ground handling load applied to the blade, stricitly anywhere and any direction but nearly always at the tip of the blade and across the blade (nominally blade lift). we use 200 lbs (as an ultimate load).
wotcha think ?
