and while we're on the subject of inertial mass, same thing with the enstrom on the back of the greenpeace ship, the swell was such, that it just threw the heli upwards due to the inertia of the rotor disc....'rpm low til ready to go' say after me....
...it's got none of that. found that out for myself in a 900 coming in hot, tail well down 45deg bank on.....it didn't like that at all....and that's why.
he'll be new to a notar, he's coming down with not enough forward speed to flare the rpm up for the cushion inertia....tries full nose down to pick up some speed an realises it's not responding in a way a 'proper' heli does flattens off confused, and pancakes it....VERY easily done in the early transition stages from t/r to notar, it's missing a HUGE inertial mass off the back end....try holding a bike wheel at the spindle, spinning it up and trying to change direction quickly...it's got none
if you were testing out new skids you would not punch a heli into the ground like this and risk damage to the rotor head or the swash links , with a thump ilke that ,,,,,,,,,
@kz4506 Right, just like if you were testing an airliner you would never rotate on takeoff until the tail scrapes on the ground, or overspeed in a dive until parts fly off. Oh wait, that's exactly what they do. I mean, parts don't always fly off, but they did with the A380, and they went back and did it again. If you're gonna sell it, you gotta prove it.
@8literbeater lol, nothing flew off! I've seen the documentaries. Things did come loose however, bolts were stripped etc. But thank God nothing flew off :)
@jlebesis Oh but it did. There's a video on here called airbus a380 flutter test, at about the 4 minute mark a piece of something ripped off the bottom. They won't show very well what it was but still… I know I don't ever want to go Mach .96 in that thing!
This is actually a test tape for the new carbon skids fitted to this chopper. The brand of skid is Impact Skids Ltd. It's a Miami based company. They make very strong heli skids for rescue and military use.
and also, the way the blades are making the upward V shape, he was low on rpm to start with! so all in all, a bad day at the office..

@bellXV15 Hogwash. That's called "coning," and it happens when the blades are loaded, from before takeoff and throughout flight.

almost looked like he hit vortex ring then tried to push out of it

Looked like a test. I can't see any other reason to do.....what ever that was. Very nice skids.

Good landing gear. Looks like a low altitude practice autorotation. Maybe part of certification testing . My guess.
