Although helicopters were developed and built during the first half-century of flight, some even reaching limited production, it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production link building specialist

The oscillations get worse (divergent oscillation) in a lateral motion (left to right).
The best way to get it to stop is not to shut off the engine and allow the blades to coast down but rather to speed them up and load the blades up (collective) as in taking off. g-string plus size lingerie
This video shows the Ground Resonance effect which is an aerodynamic phenomenon associated with fully-articulated rotor helicopters such as this one. The airframe must be in contact with the ground and the resonance is the natural vibration frequency of the airframe resulting from the design and manufacturing process. Each part of the airframe, including the rotor system, vibrates at a certain frequency. Basically this instability occurs when the frequency of the rotor couples with one of the natural frequencies of the fuselage, usually due to a shock to the airframe (during landing perhaps).The oscillations get worse (divergent oscillation) in a lateral motion (left to right).

This does appear to be a functional helo, but it appears to be an H-46 dual rotor helo, so not only is the helo suffering from resistance to it's upwards momentum, but it is affected by the opposite rotations of the dual rotors and the torque on the body, tower and synchronizing bar between to the two rotor heads. I would be more interested in watching the affects on a single rotor head chopper (w/tail rotor, of course). Which would fail first, the main rotor or tail rotor?

As an aircraft, the primary advantages of the helicopter are due to the rotor blades that revolve through the air, providing lift without requiring the aircraft to move forward the way a fixed-wing aircraft does. luxury home plans

This was not a functional helo - it looks like a test bed for the engine/rotor assembly.
Testing like this is performed so that behavior under certain conditions can be studied, in order to better understand what will happen in real-world situations, and to prevent putting life and property at risk. Its exactly the same as crashing cars in a lab. Yes, they destroy a lot of cars, but they use the data to design safer cars, and to understand what happens to people in a crash.
Its also fun to do. :-)

i mean...why would someone want to do this? it wasn't even that cool...

The helicopter must've been decommissioned.

Fucking horrible waste of taxpayer dollars. Those bastards cost millions upon millions of dollars.

That's like mechanical sado-masochism. Somewhere an F-16 is cracking one off over that.

Are the many applications for tied down helos?

Wow Someone just got fired

My guess from watching that is the air flow bounces off the ground and pushes on the blades, the force isn't constant but is strong, causing it to osscilate around and eventually break

Wow....

WTF! Who has the resources to buy a copter and tie it down? For fun?

thats pretty sweet, especially when the turbines blow out

Wow that almost looks as fun as Blogging for money.

It looks like the start of a dynamic rollover, just in fore and aft direction.
