What in the world is wrong with this helicopter?

[CZroe]

Here's a pilot saving the helicopter from ground resonance by taking off. Actually happened in the intro to a MacGyver episode and they left it in.

Yep. Notice he got it off the ground immediately. His tail dropped as well show how fast he was trying to get off the ground. Good recovery.

Good find. I'm glad I never experienced that when working in the oil field. The only time i was truly afraid in helicopters was taking off and landing on an offshore rig. When taking off and landing from the heliports, the choppers would hover then transition into forward flight in while building altitude.

Hey Rubycon, nice avatar.

If the URL doesn't work and there isn't enough to manually reconstruct the video ID, how the heck are you guys watching it? Link = Broken

Edit: That's funny. Now it works and is fully formed. It didn't work in a single one of your posts before.

You are all wrong. Can you not hear the Swahili/Aboriginai/Bun-gaiya-wompelee language being shouted in the background? Third World country equals substandard maintenance procedures. No technical orders dictating exactly how to maintain that chopper means that it never was. And if there WERE T.O.s, the natives argued about the goat/weather/demon spirit possession of the tools or hanger door instead of fixing the damn thing.

Silly backwards people.

And....the Chinese probably built the helicopter?

Made in China?

goddamn, beat me to it!

That's what happens when you substitute epoxy with Elmer's.

Or forget to correctly lube the shaft where it goes through the tight area.

If the chopper's a-rockin', don't come a-knockin!

So essentially if dampening isn't up to snuff this is likely outcome? I see a shit load of danpeners on all axis in that rotor assy

So a hard landing could cause enough damage to let the center of gravity shift off the center of rotation. That makes sense.

I do design work on mechanical systems for turbine engines, we do quite a bit of work on high speed rotating components. Luckily for what I do we can't really cause an unbalance by an impact like a hard landing, at least not a landing that wasn't hard enough to do some serious damage to the aircraft as a whole.

To both of your points;

Dampening and balance are paramount to operating that assy safely and efficently.

During build up of the sub assemblies and components all parts & hardware are meticulously kept balanced/consistant. See the colored tape on each arm?

The whole main rotor assembly is checked for balance statically and then after installation into the airframe it's dynamically tracked and balanced with the aid of accelerometers and the main rotor blade trim tabs.

That's racism and stereotyping although it's probably the case. I don't trust helicopters because one wrong thing and the thing is going down. Opposite of women

It is neither racism nor stereotyping. The Chinese make crap. It is fact. You cannot trust anything from China. Even if they claim to have met specifications you cannot be sure they used the proper alloy, heat treating procedures, or just about anything else. The ONLY way to be sure of Chinese products is for a Western company to go in to China and build the facility, provide the raw materials, and provide all the staff to watch over the Chinese workers you are using simply for labor.
